title: Temperature-heat diagram analysis method for multi-stage heat regeneration physical adsorption refrigeration cycle.

description: The method of temperature–heat (T–Q )diagram analysis was proposed in this paper. In T–Q diagram, the area between two process curves along the temperature axis represents the irreversibility degree in the heat transfer process, which has the same dimension with entransy dissipation. The diagram can be used to optimize the heat exchange configuration and the heat exchanger network of an adsorption refrigeration system. The proposed T–Q diagram and the traditional COP, exergy and entropy analysis were adopted to a multi-stage heat regenerative adsorption chiller under different heat regeneration schemes. The results show that the optimal scheme determined through T–Q diagram and cycle entropy production analysis are identical, while T–Q diagram is more intuitional since the analysis is done graphically. If consider a complete heat regeneration between two adsorption beds, the performance of the multi-stage chiller with different heat regeneration schemes should be almost the same.

title: Multivariate optimization of a heat exchanger with microchannel coil.

description: In this paper a multivariate optimization of a heat exchanger with microchannel coil has been done. Multivariate optimization included three geometry parameters of heat exchanger which, as expected, significantly influence hydrodynamic behaviour of the system. One more variable has been included in optimization process to compare gains in the heat transfer due to water inlet velocity change. Data set used for optimization has been numerically acquired and experimentally validated. Air/water side numerical model of heat exchanger composed of flat tubes with rectangular shapes has been used. Objective function that combines heat transfer rate and pressure drops of air and water has been developed and employed for an optimization procedure. Response Surface Method has been applied. Comparison of a results has been made accompanied by the commentaries and final conclusions.

title: Design and control optimization of R32 two-phase injection system using scroll compressor oriented to discharge temperature and system performance.

description: Two-phase refrigerant injection is a promising method to decrease discharge temperature of R32 compressor in severe conditions. In this work, an improved injection system with economizer was proposed to realize two-phase injection. Based on the validated distributed-parameter model of R32 scroll compressor and the steady-state cycle model, the optimization of heat transfer capability of internal heat exchanger and intermediate pressure according to system performance and discharge temperature was discussed. It is revealed that the intermediate pressure can be optimized by controlling the discharge temperature to safe limit (135°C).Through the design and control optimization of the two-phase injection system, the cooling capacity was enhanced by 7.1%~11.4% and COP was improved by 2.6%~6.2%.

title: Parkes observations for project P282 semester 2009OCTS

description: From 1989 to 2005, we have discovered a total of 23 millisecond pulsars in 47 Tucanae and obtained coherent timing solutions for 19 of those. This dataset has already allowed studies of stellar evolution and cluster dynamics and the first detection of the interstellar medium in a globular cluster. The remaining scientific objectives of this project can now be accomplished with less intensive, long-term timing: we want to keep track of the rotational phase of these pulsars and increase the number and precision of measured proper motions. The full analysis of all the previous data is still ongoing: we have recently found a new pulsar (47TucZ), and two very good new candidates, confirmed a previously know object (47TucX), and determined the timing solutions of three others (the binary pulsar with the shortest orbital period, 47 Tuc R, another eclipsing binary pulsar, 47TucW, and a newly dicovered binary, 47 Tuc Y). This has allowed the identification of these three pulsars in X-rays using Chandra and the identification of the companion of 47TucY in optical HST data. Some of the 47 Tuc pulsars are now becoming detectable at gamma-rays with Fermi, but we need to keep updated radio ephemerides.

title: Prediction model of the average size of aggregate in nano-refrigerant.

description: Nanoparticles form aggregates in nano-refrigerant. The average size of aggregate has significant effect on the heat transfer performance of nano-refrigerant. The objective of this study is to propose a model for predicting the average size of aggregate in nano-refrigerant. The average size of aggregate in nano-refrigerant depends on the coupled aggregation-sedimentation process. This process was simulated by two sub-models, i.e., the single particle motion sub-model and the particle-particle interaction sub-model. In the computing procedure, the cell-linked list (CLL) method was introduced to speed up scanning particle pairs in order to save computation time, and the constant-number method was adopted to eliminate the negative effect of aggregation on the computation accuracy. The prediction values were compared with the experimental data, and good agreement was obtained.

title: Performance analysis of a solar desiccant air conditioning system.

description: A desiccant air conditioning system driven by solar energy is proposed, and the absorption performance of two kinds of sorbent material, mesoporous silica and polymeric sorbent, which can be regenerated at relatively low temperatures were experimentally studied. Based on the experimental results of both the absorption capacity and absorption speed of each absorbent, a mathematical model was constructed considering effects of geometry parameter, operation condition and the absorption property of each sorbent. A cycle simulation model was set up to predict the operating performance of the proposed desiccant system and conventional vapor compression system including the power consumption, in-tube evaporation and condensation temperature, cooling load. A solar collector is introduced into this system to reduce the regenerative energy consumption and the system is able to be operated normally even the solar radiation is weak. The energy efficiency of the proposed hybrid cycle by using different absorbents was evaluated.

title: Experimental study on parallel flow evaporators used in roof top bus air conditionings.

description: Parallel flow evaporator with louver fins was designed for roof top bus air conditionings instead of fin-and-tube evaporators in this paper. Experimental study was conducted on parallel flow evaporators, the results showed that the heat transfer under wet condition is not significantly influenced when the inclination angle changes from 0° to 40°, while the air side pressure drop increases a lot. The effect of refrigerant charge on cooling capacity and coefficient of performance was researched to find the optimum charge amount for the bus AC system. The newly designed evaporator has the same heat capacity with the original fin-and-tube evaporator, but 57.6% volume reduction and 38% lighter.

title: Investigation on a 130 Hz miniature coaxial pulse tube cryocooler.

description: A 130 Hz miniature coaxial pulse tube cryocooler is designed and manufactured for infrared and electronic applications which limit size and mass strictly and demand fast cool down. The design goal is to provide the cooling power of over 1 W at 80 K with less than 1 kg. The operating frequency is increased up to 130 Hz and the average pressure enhanced to about 3.6 MPa so as to make up for the losses caused by the significant decrease of the cooler volume and mass. The micro compressor is scaled down from mid-size moving-coil dual-opposed linear compressors developed in the same laboratory. Scale factors based on scaling principles are modified to adapt to the micro design. The scaling process results in an overall compressor mass of nearly 650 g while resonating at 130 Hz. The no-load characteristic of the linear motor is analyzed initially. Geometrical dimensions of the coaxial cold finger and operating parameters are optimized by numerical simulations. A simulated cooling capacity of 1.71W at 80 K with an input PV power of 40 W can be achieved. The total cooler mass is estimated about 920 g.

title: Sequence Of Snow Maps Produced From Sentinel-2 Type Of Observations (Spot-5 Take 5) Over The Deux Alpes And Alpe D'Huez Ski Resorts

description: This is a series of snow cover maps between April 11 and September 8, 2015 over a region that covers the Deux Alpes and Alpe d'Huez ski resorts in France. The snow maps were produced from a SPOT-5 Take 5 images using the "Let-it-snow" processor (v1.0, June 2016: http://tully.ups-tlse.fr/grizonnet/let-it-snow).

The SEB folder contains 20 GeoTiff at 10 m résolution in Lambert-93 projection system coded as follows (cf. http://tully.ups-tlse.fr/grizonnet/let-it-snow#products-format):

    0: No-snow<br>
    100: Snow<br>
    205: Cloud including cloud shadow<br>
    254: No data

The "anim_no05jul_opt" animated gif was produced from these data after performing a simple temporal interpolation given by the following rules:


	If a pixel masked by a cloud was marked as snow in the preceding image and in the following image, then it is reclassified as a snow pixel.



	If a pixel masked by a cloud was marked as no-snow in the preceding image and in the following image, then it is reclassified as a no-snow pixel.


The July 05 image was removed from the animation due to a cloud/snow confusion. This type of error should be avoided with Sentinel-2 data thanks to an additional "high cloud" test (see http://tully.ups-tlse.fr/grizonnet/let-it-snow/blob/master/doc/tex/ATBD_CES-Neige.pdf).

These data were featured in this blog post : Gascoin, S. "Monitoring the snow cover in ski resorts using Sentinel-2" (19-Sep-2016)  http://www.cesbio.ups-tlse.fr/multitemp/?p=8676
description: The SPOT (Take5) experiments consist in using SPOT as a simulator of the image time series that ESA's Sentinel-2 mission will provide.

title: Preparation and properties of lauric acid-decanoic acid/tetradecyl alcohol-dodecane composite as PCMs for thermal energy storage.

description: The quaternary composite phase change materials (PCMs) consists of lauric acid (LA), decanoic acid (DA), tetradecyl alcohol (TA) and dodecane (DD). The mass ratio of the composite ingredients is 27.1:28.5:29.6:14.8 respectively. The composite was prepared by ultrasonic oscillations. The properties of the composite PCMs were characterized by cooling process, DSC (differential scanning calorimety), thermal cycling test and so on. The results show that the phase change temperature and latent heat of the composite are 5.13°C and 154.1J/g at 5°Cmin−1 under a constant and steady stream of nitrogen atmosphere at a flow rate of 10 ml min−1 , respectively. Hereby, the composite shows large potential in thermal energy storage, especially in air-conditioning systems, because of high latent heat, suitable phase change temperature, good thermal stability and low cost.

title: Retrofit of R-410A in a water chiller: test of four low GWP candidates.

description: R-410A is one of the main refrigerants used for air conditioning and heat pump systems. This refrigerant has a high GWP and it is nowadays question of phasing it out (European F-gas directive). In Japan, R-32 is considered as a potential replacement for R-410A (Barve, 2012). This refrigerant permits to reduce the GWP from 2090 kgeq CO2 to 675 kgeq CO2 but presents an issue with the compressor outlet temperature especially in hot climate countries. HFO refrigerants gained attention recently especially with the European mobile air conditioning regulation. These refrigerants have a GWP lower than 10 but have lower volumetric cooling capacity than R-410A and flammability issues. Refrigerant manufacturers are currently developing new refrigerant blends permitting to match heating capacity of R-410A with low GWPs. Within the AHRI AREP initiative, four low GWP candidates for R-410A replacement are tested in a water chiller. This paper presents these test results.

title: Influence of refrigerant charge and air inlet temperatures on the performance of an automotive air conditioning system.

description: One of the parameters that most affect the performance of automotive air conditioning systems is the refrigerant charge in the system. The loss of refrigerant can be caused by small leaks in hoses, gaskets and connections permeability of the refrigerant lines, accelerated by the operating conditions of the system, such as high vibration, shock, etc. The overcharge condition can be caused mainly due to system maintenance, where conditions control and charge method are not adequate. To determine these effects, tests were performed using an experimental bench with an automotive air conditioning system operating with R-134a and a block type thermostatic expansion valve. The refrigerant charge ranged from 850 to 1850 g, assuming a nominal charge of this system around 1400 g. The results showed that at a low charge condition the system was more sensitive than to overload charge condition, operating in a wide range of charges under similar conditions. From the definition of the optimum charge, the effects of air temperatures at the inlet to the condenser and evaporator also have been analysed and the results showed.

title: Analysis on the suitable working temperature range of nanofluid-based direct absorption solar collection.

description: Solar energy is often used as heat source in the refrigeration and heating system and the solar collector is the core device of solar energy heat utilization system. To solve the technical bottleneck of the coated metal-glass evacuated tube in solar medium-temperature collection, a novel solar medium-temperature heat collection method named Direct Absorption Collection (DAC) was proposed. Nano-fluid with strong solar light absorption properties as working fluid, and transparent vacuum tubes without coating was employed as solar absorber tubes. Compared with conventional solar absorber with selective coating, the solar DAC was theoretically modeled and simulated for its collection performance. The models were verified to be credible by experimental results. Both the simulative and experimental results indicated that the collection efficiency of DAC was higher than conventional coated solar absorber under a certain working temperature range. Furthermore, the performances of DAC and conventional solar collector under different operating conditions were simulated and comparatively analyzed. The suitable working temperature range of the proposed DAC under different were also obtained, providing a theoretical basis for the application of DAC.

title: Theoretical studies on the regenerator of a single-stage Stirling-type pulse tube cryocooler working at 20–35 K.

description: The regenerator is a key component of the pulse tube cryocooler because the irreversible loss from it accounts for a large part of the overall losses in the system. The improvement of the regenerator performance is thus an important task in order to enhance the cooling efficiency, especially at lower cryogenic temperatures. The paper makes numerical studies on optimizing the working parameters of a single-stage Stirling-type pulse tube cryocooler at 30 K around and introduces a method to design the diameter of sphere matrix. The numerical results indicate that the optimal sphere diameter is near 60 μm. And the optimal working parameters of the regenerator whose length and diameter is 90 mm and 16 mm are 50 Hz, 3 MPa, 2.4 g/s (cold end) and (cold end). The results of Er3Ni and Lead employed at the temperature region from 20 K to 35 K are presented. The optimal type of the multi-layer matrix is 500+Er3Ni and it can reach a no-load temperature of 23.6 K with 176 W of PV work, providing 0.31 W, 1.25 W and 2.23 W of cooling capacities at 25 K, 30 K and 35 K, respectively.

title: Parkes observations for project P282 semester 2009APRS

description: We propose to continue the timing of the millisecond pulsars in 47 Tucanae. At least 23 MSPs have been discovered, and nineteen of these have timing solutions. We propose to keep timing these to a) keep their phase connection, b) improve the precision of the proper motions and allow a detailed dynamic modeling of the cluster, c) search for gamma-ray pulsations (in collaboration with Fermi) and gravitational wave emission (in collaboration with LIGO) and d) Improve the PK parameters for 47 Tuc H, and measure the orbital variability for the eclipsing binaries.  We will, in parallel, continue searching for new pulsars in the existing data by looking into unexplored regions of parameter space.
