Abstract

The invention provides an anti-cavitation liquid feeding device which is provided with a liquid storage device and a fluorine pump, wherein a liquid inlet of the fluorine pump is communicated with a liquid inlet pipeline, and a liquid outlet of the fluorine pump is communicated with a liquid outlet pipeline; the liquid inlet pipeline is communicated with a liquid outlet of the liquid storage device by virtue of a fluorine feeding branch; a fluorine supplement branch and a refrigeration branch are respectively communicated with the liquid outlet pipeline; the liquid outlet pipeline is communicated with the liquid inlet of the fluorine pump by virtue of the fluorine supplement branch; the fluorine supplement branch is provided with a fluorine-supplement electromagnetic valve; the refrigeration branch is connected with a refrigeration device and is provided with the liquid feeding electromagnetic valve; a refrigerating circuit is communicated with the refrigeration device and the liquid inlet of the liquid storage device; the refrigerating circuit is communicated with the refrigeration branch by virtue of a circulation pipeline; the circulation pipeline is provided with a by-pass electromagnetic valve. The anti-cavitation liquid feeding device has the advantages that when the liquid level in the liquid storage device is lower than a high liquid level, a system can be switched into a self fluorine supplement mode by virtue of the electromagnetic valve, so that a refrigerant in the liquid storage device is positioned in a high liquid level, and an effect of preventing fluorine pump cavitation is realized.

Description

technical field [0001] The invention relates to the technical field of refrigeration and air conditioning, and relates to a refrigerant natural cooling type air-cooled air-cooled special air conditioner for computer rooms, which is especially suitable for the national standard GB / T 19413-2010 "Unitary Air Conditioners for Computer and Data Processing Machine Rooms". Anti-cavitation liquid supply device. Background technique [0002] With the rapid development of the communication industry, the problem of energy consumption has become increasingly prominent. The power consumption of communication switching equipment and ventilation and cooling equipment in computer rooms accounts for more than 90% of the total power consumption. Major operators are actively exploring energy-saving and emission-reduction measures. Because the power consumption of computer room air conditioners in ventilation and heat dissipation equipment accounts for more than 40% of the power consumption of ...
