Abstract
PURPOSE: To perform the air conditioning capacity stabilized regardless of the number of used rooms for a heat pump type multi-room air conditioner by providing control valves at refrigerant gas and liquid tubes and connecting the control valves of the refrigerant gas branch tubes to pressure control conduits in parallel.
CONSTITUTION: Refrigerant discharged from a compressor 66 when heating two rooms is introduced through a four-way valve 68, refrigerant gas tube 86, three-way solenoid valves 84, 85 and refrigerant gas tubes 88, 89 into indoor units 63, 64. Refrigerant liquid is introduced through liquid tubes 94, 95, solenoid valves 92, 93 and liquid tube 98 into the heat exchanger 67 of the outdoor unit 62. When conditioning one room, refrigerant gas is passes only through the solenoid valve from the branch tube 87. The refrigerant gas is partially introduced via bypass tube 104 into the liquid tube 98. On the other hand, when detecting the excessively high pressure in the refrigerant gas, a pressure control conduit 111 is operated to store the refrigerant in the conduit of the indoor unit 64 stopped. Thus, excessively high pressure is lowered to stabilize the air condioning capacity of the air conditioner.
