    摘要: An air conditioner having in a refrigeration cycle a fixed displacement-type first compression mechanism and a variable displacement-type second compression mechanism independent from each other, and also having second compression mechanism displacement control means, compression mechanism operation switching control means, an evaporator for refrigerant, a condenser, a blower, evaporator temperature detection means, and evaporator target temperature calculation means. The evaporator target temperature calculation means has first compression mechanism evaporator target temperature calculation means for calculating a target temperature for the first compression mechanism and second compression mechanism evaporator target temperature calculation means for calculating a target temperature for the second compression mechanism. When the refrigeration cycle is being operated by both compression mechanisms, the displacement of the second compression mechanism is controlled by the second compression mechanism displacement control means by referring to an evaporator temperature detected by the evaporator temperature detection means and a second compression mechanism evaporator target temperature. The air conditioner can achieve required cooling performance as equal as conventional air conditioners can do, and variations of blown air temperature, room temperature, etc. can be suppressed by controlling cooling performance finely.

    摘要: An air conditioner includes a variable displacement compressor that compresses refrigerant from an evaporator and varies a displacement according to a pressure in its control pressure chamber, and an electromagnetic valve that changes an opening such that the displacement of the refrigerant is increased in accordance with an increase in a value of current passing therethrough and changes a pressure state applied into the control pressure chamber. A control unit computes a target cooling temperature of air cooled by the evaporator, and adjusts the value of current passing through the electromagnetic valve to control the displacement so that the air temperature cooled by the evaporator approaches to the target cooling temperature. Furthermore, the control unit sets the value of current passing through the electromagnetic valve at a current value equal to or higher than a predetermined value that is determined based on an operation characteristic of the electromagnetic valve.

    摘要: A freezing prevention system for a refrigeration device includes a freezing-prevention temperature sensor for detecting a refrigerant temperature in a refrigerant evaporator, and a control unit for controlling operation of a refrigerant compressor based on the detected refrigerant temperature. The control unit includes a calculating means for calculating an integral value of the detected refrigerant temperature integrating with respect to a passed time after the detected refrigerant temperature becomes equal to or lower than 0null C. When the integral value becomes equal to or larger than a predetermined value, the control unit stops the operation of the refrigerant compressor. Accordingly, the freezing prevention system can accurately perform a freezing prevention control while its production cost can be reduced.
