摘要： A heat storage type air conditioning system capable of performing refrigerant receiving and discharging control and oil quantity control, which, in operating the general cooling circuit and the cold radiating circuit simultaneously or separately, is free from difficulties that the compressor is damaged or the cooling capacity is lowered when the quantities of refrigerant in those circuits are excessively increased or decreased, and is able to continue the operations with the quantity of refrigerant and the quantity of ice machine oil adjusted to suitable values. In the heat storage type air conditioning system, evaporators are provided in a general cooling circuit driven by a compressor and in a cold radiating circuit driven by a refrigerant gas pump, respectively, so that those circuits operate independently of each other. Furthermore, bypass circuits are provided to allow refrigerant to flow between liquid pipes and between gas pipes in those circuits. In a cold storing operation, the bypass circuits are closed, so that a cold storing circuit is formed by the compressor, a condenser, a first pressure reducing mechanism, and a cold storing heat exchanger.

摘要： A heat pump employing a capillary tube as an expansion device is disclosed. The main throttle portion of the heat pump comprises a main capillary tube and a by-pass through which a portion of the refrigerant flows and cools the refrigerant flowing through the main capillary tube. A solenoid valve for controlling the flow of refrigerant through the main capillary tube is connected to the intake of the main capillary tube, and an electrical expansion valve is connected to the intake of the by-pass for controlling the flow therethrough. An auxiliary capillary tube for cooling and an auxiliary capillary tube for heating are connected in parallel with the main throttle portion, both capillary tubes having a higher resistance to flow than the main capillary tube. The auxiliary capillary tubes increase the range over which control of the flow of refrigerant can be achieved, allowing both a smaller flow of refrigerant during under minimum cooling or heating load as well as a larger flow of refrigerant under maximum cooling or heating load.
