摘要： A method is disclosed for cooling a heat transfer fluid circulating in a cooling circuit including a chiller. The method includes installing on the circuit a vacuum housing having a heat exchange conduit extending therethrough and partially filled with a coolant and an atmosphere and pre-cooling the atmosphere and coolant within the vacuum housing to a pre-cooling temperature of between 35 and 60 degrees Fahrenheit using a conventional cooling system. Thereafter the pressure in the vacuum housing is reduced to between 1 and 500 millitorr until an initial cooling temperature in the range of of −50 to 35 degrees Fahrenheit is reached and the heat transfer fluid is then circulated through the heat exchange conduit and to the chiller and back. The pressure reduction in is obtained by selectively connecting the vacuum housing to a larger vacuum reservoir which is connected to a vacuum pump.

摘要： An air conditioner includes: a heat-source-side unit including a compressor and a heat-source-side heat exchanger; use-side units each including a use-side heat exchanger; an intermediate unit that causes the use-side heat exchanger of each of the use-side units to individually function as an evaporator or a radiator of a refrigerant; and two connection pipes that each connect the heat-source-side unit and the intermediate unit. The intermediate unit includes: an ejector that is configured to pressurize the refrigerant evaporated in the use-side heat exchanger that functions as the evaporator by using a driving flow; and a gas-liquid separator into which the refrigerant flowing out from the ejector flows.

摘要： An air conditioner includes a use-side unit, a heat source-side unit, refrigerant connection pipes, cutoff valve provided in the refrigerant connection pipes, a refrigerant leakage detector, and a controller control. When the refrigerant leakage detector detects a refrigerant leakage, the controller performs pressure reduction control to lower the pressure of the refrigerant in the use-side unit, and thereafter puts the cutoff valves into a cutoff state.

摘要： An air conditioning heat dissipation structure control method and a system includes the steps obtaining a real-time temperature Te of the heat generating component; if Te>Ted, opening the solenoid valve SV2 and adjusting the electronic expansion valve 4 to a preset initial opening degree; obtaining an update real-time temperature Te of the heat generating component after a setting time period; if the update real-time temperature Te>Tmax, performing the following steps every set period of time, obtaining a refrigerant temperature refrigerant temperature Tin at the inlet end of the refrigerant heat dissipation pipe and a refrigerant temperature Tout at the outlet end of the refrigerant heat dissipation pipe; calculating a real-time temperature difference ΔTreal-time of the inlet end temperature Tin and the outlet end temperature Tout, wherein ΔTreal-time=Tout−Tin, obtaining a preset target temperature difference ΔTtarget and calculating a deviation ΔTdeviation, ΔTdeviation=ΔTreal-time−ΔTtarget; calculating a deviation change rate ΔΔTdeviation=ΔTdeviation−ΔTdeviation′, and adjusting the opening degree of the electronic expansion valve based on the deviation ΔTdeviation and the deviation change rate ΔΔTdeviation, enables the temperature difference between the inlet end and the outlet end of the refrigerant heat dissipation pipe reaches the target temperature difference so as to ensure a good heat dissipation effect and keep the heat generating component working in a good condition and also lowers the cost by using refrigerant for transferring heat from the heat generating component. With the method, the reliability and stability of the air conditioning operation are improved, and the problem of poor heat dissipation reliability and high heat dissipation cost in the prior art is solved.
