no. 1 example

[0020] see figure 1 , The natural cooling energy-saving air conditioner includes an indoor fan 10, an outdoor fan 11 and a compressor 1, a condenser 2, a throttling device 3 and an evaporator 4 connected in sequence to form a closed loop. The compressor 1, the gas solenoid valve 6, the liquid solenoid valve 8, the indoor fan 10 and the outdoor fan 11 are respectively electrically connected to the controller 14 on the air conditioner, and the controller 14 centrally processes and controls the signals and actions of each component. A gas bypass pipeline 5 is connected between the inlet and outlet of the compressor 1, a throttle 3 is arranged between the condenser 2 and the evaporator 4, and a liquid bypass pipeline 7 is connected between the inlet and outlet of the throttle 3 .

[0021] In order to avoid various problems and hidden dangers caused by the low-temperature operation of the refrigeration system of the compressor 1 and the frequent start and stop of the compressor 1 ...

no. 2 example

[0028] see figure 2 , the liquid bypass line 7 is connected with a working fluid circulation pump 15, which is arranged at the outlet of the liquid solenoid valve 8, and is set in parallel with the restrictor 3, and the working fluid circulation pump 15 and The controller 14 is electrically connected. Its purpose is to speed up the flow of refrigerant in the condenser 2 and evaporator 4, increase the forced convection heat transfer coefficient in the tube, and further improve the heat transfer efficiency of the heat pipe. Its effect is especially obvious when it is not large.

[0029] Other unmentioned parts are the same as the first embodiment.

Abstract

The invention discloses a natural cooling energy-saving air conditioner and a control method thereof. The natural cooling energy-saving air conditioner comprises an indoor fan, an outdoor fan, and a compressor, a condenser, a throttler and an evaporator which are connected in turn to form an enclosed loop; an air bypass pipeline is connected between the inlet and the outlet of the compressor; the throttler is arranged between the condenser and the evaporator; a liquid bypass pipeline is connected between the inlet and the outlet of the throttler; the air bypass pipeline and the liquid bypass pipeline are respectively provided with a solenoid valve component which is connected in parallel with the compressor and the throttler; and a loop heat pipe LHP is formed between the evaporator and the condenser. The solenoid valve components are arranged, when the outdoor temperature is low, a natural cold source can be fully utilized to cool the indoor air through simple switching of the pipelines; therefore, the energy-saving effect is obvious, various problems and hidden troubles caused by low-temperature operation of a refrigeration system of the compressor and frequent start-stop of the compressor can be avoided, and the service life of the compressor can be effectively prolonged.

Description

technical field [0001] The invention relates to a natural cooling energy-saving air conditioner and a control method thereof. Background technique [0002] Since communication equipment is basically in a state of uninterrupted operation throughout the year and generates a lot of heat, air conditioners used in data centers, communication equipment rooms, communication base stations, etc. generally require year-round cooling operation, which consumes a lot of energy during operation, and the seasonal energy efficiency ratio Low. Moreover, since this type of air conditioner still needs to start the compressor refrigeration cycle in the cold winter, when the outdoor environment is too low, the compressor refrigeration system is prone to the problem of insufficient liquid supply caused by too low condensing pressure, and the heat load at this time is relatively high. If the compressor is small, it will also cause frequent start and stop of the compressor, which not only consumes...
