摘要： After a chiller unit is started, an opening command of 10 pulses is output to an electronic expansion valve, and after a predetermined period of time (at the time of starting with unload) elapses, an opening command of 100 to 150 pulses is output to open the electronic expansion valve up to a predetermined opening degree. Thereafter, a discharge side refrigerant super-heat TdSH is monitored and a closing command of 1 pulse/sec is output to the electronic expansion valve to drive the same in a closing direction in a short time until TdSH becomes 20 K. After TdSH has reached 20 K, a closing command of 1 pulse/3 sec is output to the electronic expansion valve, until TdSH becomes 25 K, to drive the electronic expansion valve 3 at a smaller speed in the closing direction than that speed in the closing direction until TdSH becomes 20 K. After TdSH reaches 25 K, it is judged that an operation has shifted to a stable operation, and the opening degree of the electronic expansion valve is controlled while a suction side refrigerant super-heat TsSH is monitored.

摘要： A first expansion valve is provided in an outdoor unit, and a second expansion valve is provided in an indoor unit. A pipe line connects a first joint pipe of the first expansion valve and a second joint pipe of the second expansion valve. When a refrigerant flows in from the second joint pipe and flows out from the first joint pipe, the first and second expansion valves are in a full open state due to pressure of the refrigerant. When the refrigerant flows in from the first joint pipe and flows out from the second joint pipe, the first and second expansion valves are in semi-closed state (flow rate controlling state). In a cooling mode, the second expansion valve expands the refrigerant just before an indoor heat exchanger, and in a heating mode, the first expansion valve expands the refrigerant just before an outdoor heat exchanger. In both heating and cooling mode, a large amount of refrigerant flows through the pipe line to reduce pressure loss.

摘要： A method of controlling an air conditioner includes a step of controlling an opening degree of the expansion valve and/or the number of rotations of an outdoor fan of the outdoor heat exchanger such that the difference Tx (=Te−Ti) between the temperature Te of the outdoor heat exchanger and the temperature Ti of the indoor heat exchanger is within a predetermined range, in a cooling mode in a low outside air temperature environment. Specifically, the opening degree of the expansion valve is adjusted, with the number of rotations of the outdoor fan being reduced to be smaller than that in a normal cooling mode, and then, the number of rotations of the outdoor fan is adjusted with the opening degree of the expansion valve being fixed, thereby controlling the difference Tx to be substantially constant.

摘要： An object of the present invention is to reduce electrical noise in accordance with the necessity of a countermeasure taken against electrical noise without changing a structure of an expansion valve. In a case where a judgment result as to whether or not the countermeasure against electrical noise is taken is affirmative, a drive timing (interval) of an expansion valve (107) is increased. Further, a driving amount is reduced. Accordingly, a flow of a refrigerant is made slow, whereby it is possible to reduce generated electrical noise while performing instructed temperature control.

摘要： An apparatus for controlling the temperature of an electronic device under test includes a thermal head having a temperature controlled surface for making thermal contact with the electronic device. The thermal head defines a flow channel for passage of a refrigerant fluid so as to cause transfer of thermal energy between the electronic device and the thermal head. A refrigeration system is connected in fluid communication with the flow channel of the thermal head to supply refrigerant fluid thereto. The refrigeration system includes a metering valve operative to regulate introduction of the refrigerant fluid into the thermal head. A controller is operative to control the metering valve for maintaining a predetermined temperature at the temperature controlled surface.

摘要： Disclosed are an air conditioner in which one or more compressors are operated so that the refrigerant compression capacity of the operating compressor(s) is variably changed in accordance with a cooling or heating load for cooling or heating air in a room, and a method for controlling an electronic expansion valve of the air conditioner. The air conditioner comprises a plurality of compressors for compressing a refrigerant; a condenser for condensing the refrigerant; an electronic expansion valve for expanding the refrigerant; an evaporator for evaporating the refrigerant; a direction change valve for changing the flow direction of the refrigerant; a refrigerant pipe for connecting the compressors, the condenser, the electronic expansion valve, the evaporator and the direction change valve; and a microcomputer for controlling the operation of the air conditioner, wherein an opening degree of the electronic expansion valve is controlled so that a current degree of superheat coincides with a target degree of superheat set in consideration of the refrigerant compression capacity of operating compressor(s) and an outdoor temperature. The air conditioner prevents the refrigerant in a liquid state from being introduced into the compressor(s) and the compressor(s) from overheating, and rapidly eliminates the cooling or heating load.
