    摘要: A refrigeration apparatus has a refrigerant circuit which is constituted by a compressor, a condenser, a first pressure reducer, a gas-liquid separator, a second pressure reducer and an evaporator connected to one another in series. The refrigeration apparatus also has a gas injection line connected between a gaseous phase portion of the gas-liquid separator and a compression chamber of the compressor. The improvement comprises a liquid refrigerant extracting passage providing a communication between a portion of the gas-liquid separator at a predetermined level and a portion of the low-pressure side of the refrigerant circuit. With this arrangement, it is possible to stabilize the level of the liquid refrigerant in the gas-liquid separator.

    摘要: The control system for the air-conditioner disclosed herein comprises means for setting a set value of a room temperature, means for detecting an actual value of the room temperature, means for detecting a radiant heat from walls etc. of the room as a radiation temperature, and an operational control means. The operational control means stores a comfort line which defines an inverse proportional relation between the room temperature and the radiation temperature, said comfort line depending upon set value of the room temperature. The operational control means calculates a first control index which is represented by a difference between the actual value and the set value of the room temperature and a second control index which is represented by a difference between the comfort line and the current temperature condition represented by the actual room temperature and the radiation temperature. The room temperature set value is modified in the operatal control means, according to fuzzy rule, on the basis of said first and second control indexes. The operational control means controls the air-conditioner, depending upon a difference between the modified value of the room temperature and the actual value of the room temperature, thereby providing a comfortable air-conditioned environment to a person staying in the room.
