Abstract

The invention discloses a double-booster-pump system of a precise machine room air conditioner. The double-booster-pump system comprises an intelligent controller, a booster pump module, a sensor assembly, a valve assembly, a condenser module and an evaporator module. The booster pump module comprises a first booster pump and a second booster pump which are connected in parallel, the condenser module comprises a first condenser module and a second condenser module which are connected in parallel, and the valve assembly comprises a gas input distribution valve, a cold distribution valve and a gas output distribution valve. The first booster pump and the second booster pump are connected with the first condenser module and the second condenser module respectively, a pressure stabilizing gas storage tank is arranged between the first booster pump and the second booster pump and connected with the gas output distribution valve, and the gas output distribution valve is connected with the first condenser module and the second condenser module. The double-booster-pump system adopts double-evaporator, double-booster-pump and double-condenser design, thereby having high redundancy performance, load balance, high system operation safety and high natural cold source use efficiency.

Description

technical field [0001] The invention relates to the technical field of precision air conditioners, in particular to a dual booster pump system for precision machine room air conditioners. Background technique [0002] With the development of science and technology, the power consumption and heat generation of the machines in the data center are also increasing. The use of natural cold source technology has become a new trend in the cooling research of computer rooms in recent years. In winter and transitional seasons in most parts of my country and even the world, the outdoor temperature is lower than the indoor temperature of the computer room. Proper use of the cooling capacity of the outdoor air for cooling can replace the conventional vapor compression refrigeration to a certain extent, thereby saving power consumption. Therefore, on the premise of ensuring the safe operation of the equipment in the computer room, minimizing the energy consumption of the air conditioner ...
