Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2015224845
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration cycle device which secures heating capacity and in which reliability of equipment has improved.SOLUTION: A refrigeration cycle device includes a refrigerant circuit 8. A liquid receiver 5 is provided in the refrigerant circuit 8 between an evaporator 4 and a compressor 1. When temperature of a refrigerant flowing in the evaporator 4 is below a first predetermined temperature, or the outside temperature is below a second predetermined temperature and/or when the temperature of the refrigerant discharged from the compressor 1 is equal to or greater than a third predetermined temperature, the refrigerant staying in the liquid receiver 5 is returned to the refrigerant circuit 8, and the amount of the refrigerant circulating in the refrigerant circuit 8 is increased. Thus, under the condition of low evaporation temperature, heating capacity in a heat radiator 2 is secured, and under the condition of high hot water tapping temperature, excessive increase in discharge temperature is suppressed, and reliability of the equipment can be enhanced.
