Multi-split frame type energy-saving air conditioner system and control method thereof

Abstract

The invention discloses a multi-split frame type energy-saving air conditioner system and a control method thereof. The multi-split frame type energy-saving air conditioner system is characterized in that a natural cooling condenser is respectively connected with a first evaporator, a second evaporator and a third evaporator at outside through a second electromagnetic valve, a fourth electromagnetic valve and a sixth electromagnetic valve; a refrigerant pump is respectively connected with a first condenser, a second condenser and a third condenser at outside through a first electromagnetic valve, a third electromagnetic valve and a fifth electromagnetic valve; the first evaporator is connected with the first condenser, the second evaporator is connected with the second condenser, and the third evaporator is connected with the third evaporator. The multi-split frame type energy-saving air conditioner system has the advantages that the application of single unit cabinets is supported, the application of parallel multi-split cabinets is realized, and the multi-split frame type energy-saving air conditioner system can be used as an alternative plan of modularizing machine room applications; the investment cost is low, the installation and construction speed is high, and the running efficiency is high.

Description

technical field [0001] The invention relates to the technical field of air-conditioning and refrigeration, in particular to a multi-rack energy-saving air-conditioning system and a control method thereof. Background technique [0002] In the data center industry, with the continuous growth of data information processing and application products in all walks of life, the heat density of data center servers is also getting higher and higher. Even a few kilowatts means that the heat dissipation requirements of the server are getting higher and higher, and cooling and heat dissipation applications are emerging in an endless stream. At the same time, the other impact is that the utilization and consumption of energy will also increase. Making equipment heat dissipation greener and more energy-efficient is a major challenge facing the data center air-conditioning industry. [0003] In traditional data center computer rooms, many applications directly blow cold air to the server t...

AI Technical Summary

Problems solved by technology

[0006] The large cooling capacity compressor system integrates the fluorine pump system: the compressor is built into the room, and it is impossible to realize the working mode of one condenser supplying multiple evaporators, and there are no energy-saving air conditioners with small cooling capacity (1 to 20kW) on the market. Most of the air-conditioning systems have the problem of excessive cooling capacity (common cooling capacity reaches 60kW), which cannot take into account the market application requirements of rack-mounted data center products.
