A refrigerating cycle apparatus is used in an air-conditioning system of an automotive vehicle, which is capable of operating in a hot gas bypass heating mode. Here, the discharge side of a compressor is directly connected through a hot gas bypass conduit to the inlet side of an evaporator. The evaporator acts as a radiator, heated by gas refrigerant. The compressor is stopped during operation of the apparatus in this heating mode when a physical quantity representing the high-side pressure at the compressor discharge side rises above a set value. The compressor is restarted when a physical quantity representing a heating capacity (for example the high-side pressure) falls below a set value which indicates that there is no heating capacity in the stopped state of the compressor. As a result, the heating capacity obtained through hot gas bypass can be controlled well without frequent stopping and restarting of the compressor.
摘要:
In a refrigerant cycle system, a refrigerant discharge side of a compressor is directly connected to a refrigerant inlet side of an evaporator through a hot-gas bypass passage so that the evaporator is used as a radiator during a heating mode due to the hot-gas bypass. A physical amount of refrigerant, such as a high-pressure side refrigerant pressure, flowing through the hot-gas bypass passage is detected. When the high-pressure side refrigerant pressure is decreased to a value corresponding to a refrigerant shortage area, a refrigerant shortage is determined and the compressor is stopped by a control unit. Thus, during the heating mode due to the hot-gas bypass, when a refrigerant leakage is caused in the refrigerant cycle system, the compressor is accurately protected.

A method for manufacturing polishing cloths of the class to be used with abrasive powders on a lapping machine is disclosed. The method comprises the steps of impregnating a nonwoven fabric sheet with a solution of polyurethane elastomer, wet-coagulating the impregnated sheet, and heating the resulting microporous composite sheet at a temperature higher than the softening point of the polyurethane elastomer under an essentially uncompressed condition.
