If the specification of the electronic throttle valve is determined according to the pressure difference in the working mode of the compressor, the electronic throttle valve with a small opening range should be selected, and the adjustment range is not enough when switching to the heat pipe working mode at this time; To determine the specifications of the electronic throttle valve, you should choose an electronic throttle valve with a large opening range. At this time, when switching to the compressor working mode, the adjustment range is too large and not accurate enough, resulting in overheating or insufficient steam at the output end of the evaporator. Phenomenon, reduce the cooling efficiency of the air conditioner

Embodiment Construction
[0014] figure 1 Shown is an air conditioning system with precise liquid supply heat pipe integrated unit, including evaporator (1), condenser (2), compressor (3), liquid storage tank (4), liquid pump (5), and electronic throttle valve One (6), electronic throttle valve two (7), bypass valve (8), one-way valve one (9), one-way valve two (10) and the circuit control system, all the above components are organically connected through connecting pipes As a whole, it constitutes a heat transport system combining the compressor cooling mode and the power heat pipe cooling mode, in which the circuit control system controls the opening and closing of the compressor (3) and the liquid pump (5), thereby controlling the compressor (3) and the liquid pump (5). Switching between cooling mode and power heat pipe cooling mode.
[0015] When the system works in compressor cooling mode, such as figure 2 As shown, the compressor (3) is turned on, the one-way valve (9) and the electronic throt...

The invention discloses an air-conditioning system with a precision liquid supply type heat pipe integrated machine, which mainly consists of an evaporator, a condenser, a compressor, a liquid storage tank, a liquid pump, a bypass valve, two electronic throttle valves, and two one-way valves. Composed of a circuit control system, the all-in-one air-conditioning system uses two electronic throttle valves with different opening ranges in the compressor working mode and the heat pipe working mode, so that the control range of the electronic throttle valve is more precise. When the ambient temperature is high, the compressor working mode is turned on, and the system has a large pressure difference, and an electronic throttle valve with a small opening range is selected; when the ambient temperature is low, the heat pipe working mode is turned on, and the system has a small pressure difference. For differential pressure, select an electronic throttle valve with a large opening range. The invention avoids the phenomenon of overheating or insufficient steam at the output end of the evaporator due to inaccurate liquid supply, effectively improves the heat exchange efficiency and increases the heat exchange capacity, and can be applied to electronic equipment, power equipment, computer rooms, communication Heat dissipation and temperature control elements in the computer room.
Description
technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration, and in particular relates to an air-conditioning system with a precise liquid-supply heat pipe integrated machine. Background technique [0002] Due to the high equipment density and high heat generation in the communication equipment room and data center, the equipment room system has certain requirements on the temperature, humidity and dust concentration of the environment, so an air conditioning system should be installed. In order to save energy, the heat pipe integrated air conditioning system combining the heat pipe system and the compressor system is selected. [0003] At present, an electronic throttle valve is used in the heat pipe air conditioner all-in-one system, but the pressure difference inside the system in the compressor working mode and the heat pipe working mode is quite different. If the specification of the electronic throttle valve is determined ...
