An anti-cavitation liquid supply device and a refrigeration system based on the device

Abstract

The anti-cavitation liquid supply device of the present invention is provided with a liquid reservoir and a fluorine pump, a liquid inlet pipeline is connected with the liquid inlet of the fluorine pump, and a liquid outlet pipeline is connected with the liquid outlet of the fluorine pump, The liquid inlet line is connected to the liquid outlet of the liquid storage through the fluorine supply branch; the fluorine replenishment branch and the refrigeration branch are connected to the liquid outlet respectively, and the liquid outlet line is connected to the fluorine pump through the fluorine replenishment branch. The liquid inlet is connected and set, and a fluorine replenishing electromagnetic valve is arranged on the fluorine replenishing branch; the refrigeration branch is connected with the refrigeration device, and a liquid supply solenoid valve is arranged on the refrigeration branch; the liquid inlet connected to the refrigeration device and the liquid storage A refrigerating circuit is provided at the port, and the refrigerating circuit and the refrigerating branch circuit are connected and arranged through a circulation pipeline, and a bypass solenoid valve is arranged on the circulation pipeline. In the anti-cavitation liquid supply device of the present invention, when the liquid level in the liquid reservoir is lower than the high liquid level, the system can switch to the self-supplementing fluorine mode through the solenoid valve, so that the refrigerant in the liquid storage device is at a high liquid level, realizing the prevention of Fluorine pump cavitation effect.

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 ...
