A. Project description
A.1. Title of the JCM projectIntroduction of High Efficiency Centrifugal Chiller and Electric Heat Pump Type Water Heaterin Hotel
A.2. General description of project and applied technologies and/or measures
The proposed JCM project aims to reduce CO2 emissions by introducing the high efficiency
chiller and water heater system to the hotel located in San Jose, Costa Rica.
The high efficiency chiller equipped with an optimized control function, including inverter,
enables to improve the energy efficiency while continuously regulating the room temperature.
In addition, the high efficiency water heater can supply hot water by using waste heat of chiller
and reduce the consumption of fossil fuel which was used for the conventional boilers for hot
water supply.
In the project, steam from auxiliary boiler is used not only to (ⅰ) heat the water, but also for(ⅱ) the laundry and kitchen. However, records of boiler fuel are not measured for those 2 uses
respectively. This requires additional two steam meters to calculate boiler fuel used for heatingwater. They measure steam quantity used for (ⅰ) water heating and (ⅱ) kitchen and laundry
respectively. Monitoring parameter “Fuel consumption of auxiliary boiler, ACPJB,l,p” inapproved methodology is obtained by apportioning calculation using measured steam quantityof the two uses mentioned above.
Measuring are conducting by 2 orifice plate flowmeters, which are precise mechanicalmetering devices equipped with temperature and pressure sensors and a differential pressure
cell to compensate for any variations on fluid density. These flowmeters directly measures
steam flow rate, therefore boiler fuel used for heating water are obtained by multiplying total
boiler fuel consumption and proportion of steam rate for heating water.

A.6. Contribution from developed countries
The proposed JCM Project was partially supported by the Ministry of Environment, Japanthrough the financing programme for JCM model projects, which provided financial support
up to 50% of initial investment for the projects in order to acquire JCM credits.
The technology of advanced and efficient centrifugal chiller system is introduced in theproposed project by the Japanese project participant. The Japanese project participant transfers
the technology through conducting the training on operation and maintenance of newly
installed equipment through trial operation.

Project information

Project chiller is an inverter type centrifugal chiller
with a capacity ranging from 165USRt to
3500USRt.
Note : 1 USRt = 3.52 kW
IPLV for project chiller i certified by AHRI is morethan the threshold IPLV values set in the tablebelow. (“x” in the table represents cooling capacity

used in the existing chiller to the air (e.g. re-use ofthe equipment) is prepared. Execution of this planis checked at the time of verification, in order toconfirm that refrigerant used for the existing one
replaced by the project is prevented from being
released to the air.

As written in A.2., Monitoring parameter “Fuel consumption of auxiliary boiler, ACPJB,l,p” iscalculated by multiplying total fuel consumption (measured in Monitoring point (6)) andproportion of steam quantity for heating water obtained by monitoring. (ACPJB,l,p is calculated inAppendix1)
Typical schematic of complementally monitoring is below.
