PURPOSE:To enable continuance of operation of a device without effecting low pressure cut by a method wherein opening and closing of a solenoid valve in a bypass passage is controlled according to a change in a peripheral temperature by a peripheral temperature detecting part and a low pressure ...
PURPOSE:To detect the degree of excess heat of refrigerant which flows out from a refrigerant vaporizer and detect the end of refrigerant recovery definitely by installing a detection means to detect the end of refrigerant recovery. CONSTITUTION:As the amount of refrigerant in a refrigerating cycle ...
PURPOSE:To facilitate a charging of refrigerants in case of installing an air conditioner and to enable the refrigerant to be recovered by a method wherein in the case where a sensed pressure of a first pressure sensor is more than a predetermined value, a third solenoid valve is closed and...
PURPOSE:To perform an efficient recovery of refrigerant by a method wherein an interior part of a cooling system is made into a vacuum state, a supplying passage ranging from a storage tank to a connection means is formed and refrigerant stored in the storing tank is supplied to the cooling...
PURPOSE:To reduce the amount of refrigerant and improve the thermal efficiency in a reverse Carnot cycle apparatus by a method wherein a linear valve type expansion valve is brought in pulse action to produce the jet-atomized refrigerant that flows into an evaporator. CONSTITUTION:In an apparatus...
PURPOSE:To permit pouring of the proper amount of refrigerant simply without any excess or shortage of the refrigerant by a method wherein a refrigerant filling detecting sensor, detecting the liquid and gas mixing condition of the refrigerant and outputting an electric signal for opening a power ...
PURPOSE:To permit the recovery of refrigerant without elongating recovery time by a method wherein a refrigerant recovering vessel is provided with an air extracting means for discharging air, which flows from a refrigerating cycle, from which the refrigerant is recovered, into the refrigerant recoveri...
