摘要： The composition of a refrigerant in a refrigeration cycle is detected, so that the refrigeration cycle is controlled by a control method in accordance with the detected composition. A control target value is set in accordance with the detected composition, and when the composition is varied, the control target is changed in accordance with that variation. As a result, even when the refrigerant composition is varied, the refrigeration cycle can be operated stably. The refrigeration cycle uses a non-azeotrope refrigerant, and includes a device for detecting the composition of a non-azeotrope refrigerant; a device for detecting the operating state of the refrigeration cycle, i.e., status values to be controlled, such as temperature or pressure; a computation control apparatus for accepting composition, temperature, pressure or the like, detected by the detecting device as inputs and for performing signal conversion, computation control for control targets, or the like; and a drive apparatus for driving the components of the refrigeration cycle, such as a compressor or a refrigerant pressure reduction apparatus.

摘要： A refrigerant flow control system associated with a refrigerant circulating circuit having a compressor, a condenser, an expansion valve and an evaporator, includes a branch pipe extending from a discharge pipe of the compressor and having on sealed free end. A first temperature sensor is disposed on the branch pipe near the sealed free end for detecting a condensation temperature of a refrigerant which is condensed in the branch pipe. A second temperature sensor is disposed on the discharge pipe of the compressor for detecting a temperature of the gaseous refrigerant discharged from the compressor. The signals representative of the condensation temperature and the temperature of the discharge gaseous refrigerant are inputted to a control device. The control device calculates a difference between the two detected temperatures, and a degree of superheat of the discharged gaseous refrigerant and transfers to the expansion valve a command signal representative of the calculation results, thereby controlling an opening of the expansion valve.

摘要： In a refrigerating cycle in which a constant speed type compressor, an indoor heat exchanger and an outdoor heat exchanger are connected one by one by means of piping, a receiver is provided between the indoor and outdoor heat exchangers, and no capacity control mechanism is provided for the compressor, a gas-liquid flow rate regulating device is associated with the receiver for regulating at least either of liquid flow rate and gas flow rate of a cooling fluid which flows into and out of the receiver. This causes a quantity of excess refrigerant stored in the receiver to change to thereby vary an effective quantity of refrigerant circulating through the refrigerating cycle.

摘要： An air-conditioner system having a compressor, a plurality of heat exchangers for heating or cooling the air in a room, a radiator for transferring heat energy of refrigerant outside of the room, a plurality of orifices, a manifold with a main port and a plurality of sub-ports, flow direction control multi-port valves directing the flow of the refrigerant from the compressor to the main port and not from the main port to the compressor when at least one of the heat-exchangers is heating the room. The refrigerant does not flow from the compressor to the radiator when at least one of the heat exchangers is heating and none of the heat exchangers is cooling. Also, it does not flow from the compressor to the main port but flows instead from the compressor to the radiator and from the main port to the compressor when none of the heat exchangers is heating and at least one of the heat exchangers is cooling. The system also employs a plurality of valve pairs each of which having a first valve and second valve such that the first valve opens (closes) when the second valve closes (opens). The first valves are arranged for providing flow of refrigerant to the inlet of the compressor from the heat exchangers and the second valves provide flow of refrigerant from the outlet port of the compressor to the respective heat exchanger first ports via the sub-ports of the manifold.

摘要： A refrigerating system having a refrigerating cycle constructed by connecting an accumulator, a refrigerant compressor, a four-way valve, an outdoor unit heat exchanger, an outdoor unit expander, a receiver, an indoor unit expander and an indoor unit heat exchanger sequentially by pipes. Normally, excessive refrigerant is stored in the receiver and when it becomes necessary to raise a ratio of lower boiling point refrigerants, a flow amount of the refrigerant is decreased by restricting the outdoor unit expander during the cooling operation or by restricting the indoor unit expander during the heating operation to move the excessive refrigerant within the receiver to the accumulator. Thereby, the composition of the refrigerant circulating within the refrigerating system using non-azeotrophic refrigerant mixtures may be changed without using a complicated system structure or control method thereof and the capacity of the refrigerating cycle may be changed.
