title: Numerical investigation of evaporator design in the ejector refrigeration cycle with R134a and CO2.

description: Two-phase ejector studies often focus on the design and performance of the two-phase ejector and the effect it has on the performance of the ejector system. However, recent work has shown that evaporator design can also have a very significant effect on ejector cycle performance. In the present study, a numerical model of a microchannel air-to-refrigerant evaporator is developed and incorporated into thermodynamic models of the standard ejector and DX cycles. The models are used to investigate the effect of evaporator geometry, specifically the microchannel port hydraulic diameter, on the performance of the cycles. The analysis is performed using the refrigerants R134a and CO2, and the behavior of the two refrigerants with varying diameter is compared. The effects of evaporator outlet state and height-to-width ratio are also investigated. It is shown that evaporator design, not just ejector design, can have a significant effect on the COP of the ejector cycles.

title: Theoretical comparisons between absorption heat pump and electrical heat pump for low temperature heating.

description: Energy consumption for heating and DHW is very high, and heat pump technologies are becoming popular. Air source absorption heat pump (ASAHP) and air source electrical heat pump (ASEHP), ground source absorption heat pump (GSAHP) and ground source electrical heat pump (GSEHP) are theoretically compared. Comparisons between ASAHP and ASEHP indicated that: (1) ASAHP is advantageous over ASEHP under colder conditions; (2) exergy efficiency of ASAHP is higher than that of ASEHP in most conditions; (3) high-efficiency ASAHP is always more emission-reduction than ASEHP, while low efficiency ASAHP is more emission-reduction than ASEHP when ambient is below 0°C. Comparisons between GSAHP and GSEHP revealed that: (1) annual primary energy efficiency of high-efficiency GSAHP is higher than that of GSEHP, while low-efficiency GSAHP is worse than GSEHP; (2) GSAHP is more suitable for colder regions with reduced thermal imbalance; (3) borehole number of GSEHP can be reduced by 40~50% using GSAHP.

title: OATS_201601 Injected Errors Study 2

description: Older Adults Text-entry Studies (OATS):
Our goal was to capture participants’ typing behaviour during input in a lab setting and determine the efficiency of the highlighting keyboard error support mechanism. In this experiment we introduced a new type of experiment, designed to overcome the problem of participants typing in very carefully (i.e. the “injected error” algorithm). This time the algorithm was modified to overcome some limitations encountered in a previous experiment (2015-04). The experiment involved only younger users.

title: A new model for refrigerant boiling inside a brazed plate heat exchanger (BPHE).

description: This paper presents a new model for refrigerant boiling inside Brazed Plate Heat Exchangers (BPHEs) based on a set of 251 experimental data previously obtained by the authors which includes data points relative to HFC refrigerants (HFC236a, HFC134a, HFC410A), HC refrigerants (HC600a-Isobutane, HC290-Propane, HC1270-Propylene), and also a new low Global Warming Potential (GWP) HFO refrigerant (HFO1234yf). The new model includes specific equations for nucleate and convective boiling. The new model was compared against a set of 505 experimental data obtained by different laboratories which includes HFC134a, HFC410A, HFC507A and HCFC22 data points with different plate geometry. The mean absolute percentage deviation between experimental and calculated data is around 20%.

title: HFC32 vaporisation inside a brazed plate heat exchanger (BPHE).

description: This paper presents HFC32 boiling heat transfer coefficients measured inside a small Brazed Plate Heat Exchanger (BPHE): the effects of heat flux, saturation temperature (pressure), and outlet conditions are investigated. The experimental tests were carried out at three different saturation temperatures (10, 15, and 20°C) and four different evaporator outlet conditions (vapour quality around 0.80 and 1.00, vapour superheating around 5 and 10°C). The heat transfer coefficients show great sensitivity to heat flux and outlet conditions and weak sensitivity to saturation temperature (pressure). The saturated boiling heat transfer coefficients were compared with a new model for refrigerant vaporisation inside BPHE: the mean absolute percentage deviation between calculated and experimental data is 4.7%. HFC32 exhibits heat transfer coefficients 20-30% lower than those of HFC410A under the same operating conditions.

title: Bivalent air-conditioning system for a supermarket.

description: This paper presents a possible alternative solution to cold and heat supply a commercial space located in Brasov. The proposed solution uses absorption systems are more economical and have a lower impact on the environment. The proposed scheme is the result of experimental research conducted by a team from the Thermodynamics, Heat Transfer and Thermal Equipment Department. The tests were performed on an existing plant in the Thermodynamics Laboratory of the Technical University of Civil Engineering Bucharest. The authors present the performance of classical power plant with cold and heat, the same commercial space, the preparation of cold water with mechanical compression refrigeration systems, operated by electricity. Energy savings brought by the proposed solution is given by the hot water to drive the absorption refrigeration systems with solar collectors in most of the time with thermal boiler at peak times. This cooling solution with application to commercial spaces completely new to Romania is supported by overlapping solar heatstroke cold requirement of the complex. The authors present an economic analysis on energy savings and payback time.

title: Adsorption characteristics of ethanol onto promising adsorbents for adsorption cooling applications.

description: Adsorption characteristics of ethanol onto three promising adsorbents have been investigated for developing high performance adsorption chillers. Adsorbents used in the present study are (i) parent Maxsorb III, (ii) two adsorbents based on spherical phenol resin treated with different mass ratios of KOH named as KOH4-PR and KOH6-PR. Adsorption equilibrium and kinetics of the assorted pairs have been measured using magnetic suspension adsorption measurement unit. The Dubinin-Astakhov (D-A) and Dubinin–Radushkevich (D-R) equations are used to fit adsorption isotherms whilst adsorption kinetics is presented by Fickian diffusion model. The pressure-temperature-concentration diagrams of the studied adsorbents have also been presented. Experimental results show that the adsorption equilibrium capacities of KOH6-PR/ethanol, KOH4-PR/ethanol and Maxsorb III/ethanol pairs are 2, 1.43 and 1.2 kg kg-1, respectively. The diffusion time constant of KOH4-PR is found to be higher than that of other studied adsorbents especially at the lower range of adsorption temperatures.

title: Les cadres supérieurs et la globalisation dans les villes [2006 - 2007]

description: Cette enquête a été lancée sur les cadres supérieurs dans les villes de Paris, Lyon, Madrid, Milan et Londres, sur leur organisation dans la ville, les stratégies de différenciation qu'ils mettent en œuvre, les processus de ségrégation, de gentrification qu'ils contribuent à développer. Les cadres supérieurs les plus mondialisés ont des stratégies très familiales en même temps que des stratégies professionnelles. L'enquête montre l'attitude critique forte de la société française considérée comme incapable de s'adapter à la mondialisation de la part des parents mais que cette attitude se retrouve à Madrid et à Milan. La façon dont ces cadres vivent la ville est abordée.

title: Environmental impact of possible replacements for R22.

description: This paper presents a comparative analysis of a number of potential replacement refrigerant for R22 used for different refrigeration plants and heating pumps from an environmental impact perspective (the TEWI coefficient). In order to assess environmental impact of these potential substituents, the following refrigerants have been considered: a) substitutes currently used in existing systems: R134a, R290, R600a, R152a, R507, R407C, R404A, R410A; b) new substitutes, recommended for new systems: R417A; R422A; R424A; R427A, R428A. The paper covers a comparative analysis of three types of refrigeration plants which operate with different refrigerants from a factor TEWI perspective, as follows: 1. air conditioning-split unit, with a cooling capacity of 10,55 kW (tin = 25°C, tambiant = 35°C); 2. air cooled chiller, with a cooling capacity of 11.3 kW (tchilled water in/out = 7°/12°C, tamb = 35°C); 3. air cooled refrigeration system using direct or indirect evaporation for cold storage (medium temperature space tint = 0°C and low temperature space tint = -20°C, tambiant = 35°C), cooling capacity 11.3 kW.

title: Optimal design of heat exchangers of the heat pipe combined evaporative cooling room air conditioner.

description: In order to improve the energy efficiency of traditional room air conditioners, this paper presented the heat pipe combined evaporative cooling room air conditioner. This study built the mathematical model and carried out programming to make simulation analysis on the annual dynamical operating performance of the heat pipe combined evaporative cooling room air conditioner under different area parameters of heat exchangers, and then took into account the economic factors, to obtain that the optimal areas of evaporator and condenser were respectively 14.89 m2 and 23.07 m2. In addition, based on the optimal areas, it was concluded that the COP of the combined room air conditioner increased by 33.27%, and energy consumption reduced by 32.83%, comparing with traditional air conditioner, which didn’t include evaporative cooling technology and separate type heat pipe technology.

title: Theoretical analysis of a new hybrid system with two ejectors.

description: Theoretical analysis of a new energy system. The proposed cycle combines the Rankine cycle and the ejector refrigeration cycle by adding a turbine between the boiler and the two ejectors. The combined cycle can produce both power and refrigeration at two different pressure and temperature levels with only one heat source. A simulation was carried out to evaluate the cycle performance using R123 as a working fluid. A one-dimensional mathematical model of the ejector was developed using the equations governing the flow and thermodynamics based on the constant-area ejector flow model. The ejector is studied in optimal operating regime. The model includes effects of friction at the constant area mixing chamber. The programming language is FORTRAN and thermophysical properties of refrigerants are evaluated using the base REFPROP V 9.1.The influence of thermodynamic parameters on the system performances is studied. The results show that the condenser temperature, the evaporation temperatures, the extraction ratio, the turbine inlet pressure and temperature has a significant effect on the system performances.
