Fluorine pump system and control method thereof

Abstract

The invention discloses a fluorine pump system and a control method thereof. A condenser is a double-coil heat exchanger and comprises a condenser coil A and a condenser coil B; the compressor, the condenser coil A, the electronic expansion valve and the intermediate heat exchanger form a first refrigeration cycle, the indoor terminal, the electric flow regulating valve III, the intermediate heat exchanger, the electric flow regulating valve II, the liquid storage tank and the refrigerant pump form a second refrigeration cycle, and the first refrigeration cycle and the second refrigeration cycle exchange heat in the intermediate heat exchanger; and the indoor tail end, the electric flow regulating valve IV, the condenser coil pipe B, the electric flow regulating valve I, the liquid storage tank and the refrigerant pump form a third refrigeration cycle. The refrigerant in the first refrigeration cycle of the intermediate heat exchanger is separated from the refrigerant at the tail end in the supply chamber, so that the oil return problem of the refrigeration system under the conditions of long pipeline and height difference is solved, and higher applicability is achieved; meanwhile, the system has three operation modes, a compressor or a natural cold source can be used according to different working conditions, and energy consumption is reduced.

Description

Technical field [0001] The present invention relates to a refrigeration apparatus, particularly relates to a fluorine-pump system and a control method. Background technique [0002] In recent years, north of Guangzhou-Shenzhen and other major cities have introduced the relevant provisions of the new data center, and strictly control the scale data center construction and energy consumption indicators PUE, guide large and very large data center energy use efficiency is not higher than 1.4. The main measures to reduce energy consumption indicators PUE room is to minimize the energy consumption of non-essential equipment, such as computer room air-conditioned environment of auxiliary equipment. How to reduce the energy consumption of computer room air conditioning is becoming increasingly popular topic, indirect evaporative cooling system, air conditioning full frequency fluoride pumps have emerged. Indirect evaporative cooling system for the engine room high infrastructure requirem...

AI Technical Summary

Problems solved by technology

The full frequency conversion fluorine pump air conditioner adopts the frequency conversion compressor system, and it is a distributed arrangement. However, due to the characteristics of the compressor itself, under the conditions of super long pipelines and height differences, especially high negative height differences, the compressor oil return problem and the problem of cooling capacity attenuation is inevitable
