Summary

In this report, aiming to rationalize its design, operation and maintenance, the authors describe a practical study carried out to verify its performance both in the development phase and throughout changes due to age and results of the field test for verification of its performance are presented. It was found that the heat pump unit using ammonia refrigerant can be handled as well as the heat pump unit using a fluorocarbon refrigerant such as HFC. Thus, the reliability and safety of this heat pump unit using ammonia refrigerant was verified.
