Air conditioning / hot water supply and control method for the air conditioning / hot water supply

摘要

An air conditioning and hot water supply (100), comprising: a refrigerant circuit air conditioning (5) forming an air cycle conditioning by circulating an air conditioning refrigerant, a refrigerant circuit supply hot water (6) forming a cycle of hot water supply by circulating a cooling of hot water supply, and a control device (1a); one intermediate heat exchanger (23) connected in parallel with a heat exchanger side of the heat source air conditioner (24) for exchanging heat between the air conditioning refrigerant and the atmosphere in the refrigerant circuit air conditioning ( 5), and connected in parallel with a heat exchanger side of the heat source hot water supply (44) for exchanging heat between the refrigerant supply hot water and the atmosphere in the refrigerant circuit supply hot water (6) for heat exchange between the air conditioning refrigerant and the refrigerant supply hot water; means quantity adjusting inflow of air conditioning refrigerant configured to adjust an amount of air conditioning refrigerant flowing into the heat exchanger side of the heat source heat air conditioner (24) or the exchanger intermediate heat (23) in a cooling operation using the air conditioning cycle; and configured to measure a temperature of an outlet of the heat exchanger air conditioning heat exchanger side of the heat source air conditioner (24) or the intermediate heat exchanger (23) means in which the amount of air conditioning refrigerant flowing into the heat exchanger side of the heat source air conditioner (24) or the intermediate heat exchanger (23) is set to the cooling operation; characterized in that the control device (1a) calculates an amount of heat radiation from air conditioning in the refrigerant circuit air conditioner (5), an amount of heat absorption of hot water supply in the refrigerant circuit supply hot water (6), a target temperature condensation in the refrigerant circuit air conditioning (5), and a target evaporation temperature in the refrigerant circuit of the hot water supply (6) in a case where the cooling operation using the air conditioning cycle and an operation of supplying hot water by cycle hot water supply run simultaneously; and when the amount of heat radiation from air conditioning is greater than the amount of heat absorption of hot water supply, the coolant supply hot water is blocked and does not flow into the heat exchanger side of the heat source of hot water supply (44) by locking means refrigerant supply hot water, and the amount of the locking means of refrigerant supply hot water, and the amount of air conditioning refrigerant flowing into the heat exchanger side of the heat source air conditioner (24) or the intermediate heat exchanger (23) is adjusted by controlling the adjusting means amount of inflow of air conditioning refrigerant based on the temperature of the heat exchanger outlet air conditioning.
