摘要： PROBLEM TO BE SOLVED: To reduce a working pressure as low as possible in strong winds to prevent the abnormal rise of discharge pressure and the stop of a compressor due to the operation of a pressure breaker, and to perform operation while enlarging an operable pressure range in a stably operable state. SOLUTION: This air conditioner includes an outdoor unit, an indoor unit, connection piping for connecting the outdoor unit to the indoor unit, a refrigerating cycle and a control part. In the pressure breaker, its breaking pressure for stopping the operation of the air conditioner is set to be less than an allowable pressure of existing connection piping. In air-conditioning operation, when performing operation after the pressure breaker detects the breaking pressure and stops operation, the control part controls the compressor, an outdoor blower or an electronic expansion valve to make a high pressure side pressure lower than the normal operating pressure. According to the breaking frequency of the pressure breaker within a fixed time, the high pressure side pressure for which the control part controls the compressor, the outdoor blower or the electronic expansion valve, is made lower in high breaking frequency rather than in low breaking frequency.

摘要： PROBLEM TO BE SOLVED: To solve a problem of falling in a hunting state when a state of an outlet of an evaporator is saturated, though an evaporating capability becomes a maximum, due to excessively moistening or drying by aiming at a saturated state. SOLUTION: A refrigerating cycle system comprises a re-evaporating means for moistening the state of the outlet of the evaporator to superheat a refrigerant at a site from the outlet of the evaporator to an inlet of a compressor, and a controller for controlling a superheat degree of the sucked refrigerator of the inlet of the compressor and a supercooling degree of the refrigerant of the outlet of a condenser. Thus, the controller controls the superheat degree of the refrigerant of the inlet of the compressor and the superheat degree of the refrigerant of the outlet of the condenser.

摘要： PROBLEM TO BE SOLVED: To restrain the liquid backing of a liquid refrigerant into a compressor, which is caused by the overflow of the liquid refrigerant in an accumulator due to the liquid backing from an outdoor heat exchanger after starting heating operation, by a method wherein a second liquid receiver is provided above a first liquid receiver and the lower part of the second liquid receiver is connected to the first liquid receiver through a connecting tube. SOLUTION: A second liquid receiver 7 is provided above a first liquid receiver 4 and the lower part of the second liquid receiver 7 is connected to the first liquid receiver 4 through a connecting tube 8. High-temperature high-pressure gas, discharged out of a compressor 1, is sent into an indoor heat exchanger 6 through a four-way valve 2 and, thereafter, heat exchange is effected in the indoor heat exchanger 6 with indoor air whereby the refrigerant is condensed and is changed into super-cooled refrigerant. The refrigerant is expanded in a choking unit 5 through adiabatic expansion and, thereafter, the liquid refrigerant flows into a middle-pressure receiver 4 under two-phase status of gas and liquid. According to this method, the overflow of liquid refrigerant in an accumulator upon starting is restrained and the liquid backing into the compressor 1 is avoided whereby troubles, such as the forced stopping of the compressor 1 and the like, can be eliminated.

摘要： PROBLEM TO BE SOLVED: To suppress fluctuation in the composition of circulating refrigerant due to excess refrigerant by coupling a four-way valve with a compressor, a condenser and an evaporator, coupling an accumulator and the evaporator, respectively, with the other end of the compressor and the condenser, and disposing throttle valves, respectively, between an inner receiver and the condenser and evaporator. SOLUTION: High temperature high pressure gas refrigerant delivered from a compressor 1 passes through a four-way valve 2 and enters into an outdoor heat exchanger 3 where heat is exchanged with outer air to produce liquid refrigerant flowing into a first throttle valve 4a. The refrigerant enters into a receiver 7 with pressure being reduced and cooled down to saturated liquid state by low temperature low pressure refrigerant flowing through an accumulator 6. When an equivalent evaporation temperature is sustained through temperature glide in two-phase region of the characteristics of nonazeotropic mixture refrigerant, pressure at the inlet of an indoor heat exchanger 5 increases before being brought to low temperature low pressure by a second throttle valve 4b. Since pressure of the mixture refrigerant stored in the receiver 7 is increased, excess refrigerant is not stored in the accumulator 6 and fluctuation in the composition of circulating refrigerant is suppressed.
