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 improve an expansion efficiency in a capillary tube for a refrigerating/air-conditioning device and prevent the lowering of flow rate of refrigerant, which is due to the adhesion of sludge in the same tube. SOLUTION: A capillary tube 28 is provided with at least one place of projected part 29 on the inner surface of the same to improve an expansion efficiency by the choking effect of refrigerant, which is caused by the projected part 29. The projected part 29 can be formed easily by applying a pushing force from the outside of the capillary tube 28 to deform the same through plastic deformation. On the other hand, the film 30 of a water repellent material is formed on the inner surface of the capillary tube 28 whereby the adhesion of sludge can be reduced remarkably. The film 30 of water repellent material is formed by forming the film 31 of a surfactant on the inner surface of the capillary tube 28, then, the water repellent material is applied thereon whereby an uniform film can be formed while a firing process is applied if necessary in accordance with the nature of the water repellent material.

摘要： PROBLEM TO BE SOLVED: To stably assure desired capability in both cooling and heating by using a non-azeotrope refrigerant containing a refrigerant having a low boiling point, a small specific volume and larger latent heat than another refrigerant to be mixed and a refrigerant having a high boiling point, a large specific volume and smaller latent heat than the another refrigerant. SOLUTION: In the air conditioner comprising an outdoor side unit 30 having a compressor 1, a four-way valve 2 and an outdoor heat exchanger 3, and an indoor side unit 40 having an indoor heat exchanger 5 or the like, a refrigerant sealed in an annular refrigerating circuit is specified. That is, as the refrigerant, a non-azeotrope refrigerant containing a refrigerant having a low boiling point, a small specific volume under pressure of the step of sucking the refrigerant to the compressor and larger latent heat than that of another refrigerant to be mixed therewith and a refrigerant having a high boiling point, a large specific volume under pressure of the step of sucking the refrigerant to the compressor and smaller latent heat than that of the another refrigerant is used. Thus, when heated, or when cooled, the refrigerant can flow in gas-liquid phase state through a liquid extension piping between both the units 30 and 40.

摘要： PROBLEM TO BE SOLVED: To provide an air-conditioning apparatus which can control power consumption in an apparatus stopped state by preventing the accumulation of refrigerants by a compressor without excessively heating the compressor.SOLUTION: When a compressor 1 is in a stopped state and an outside air temperature change rate Tah exceeds zero, a first heating operation is started, and a heating capacity of a compressor heating portion 10 is set within a range equal to or smaller the heating capacity upper limit Pmax based on the outside air temperature change rate Tah. A remaining refrigerant liquid amount Ms as a refrigerant amount condensed in the compressor 1 that is not evaporated even through a first heating operation is acquired based on the outside air temperature change rate Tah and the heating capacity. If the outside air temperature change rate Tah is zero or below and the remaining refrigerant liquid amount Ms exceeds zero while the compressor 1 is in a stopped state, a second heating operation is started, and the compressor heating portion 10 is controlled based on the remaining refrigerant liquid amount Ms, and the refrigerant condensed in the compressor 1 is evaporated.
