Double-cold source integrated air-conditioning system

Abstract

The invention relates to a double-cold source integrated air-conditioning system, which comprises a refrigeration air-conditioning subsystem, a heat pipe subsystem, an evaporation fan and a condensation fan, wherein the refrigeration air-conditioning subsystem comprises a compressor, an evaporator, a condenser and an expansion valve; the expansion valve, the evaporator, the compressor and the condenser are connected sequentially; the heat pipe subsystem comprises a heat pipe indoor heat exchanger and a heat pipe outdoor heat exchanger; the heat pipe indoor heat exchanger is connected with the heat pipe outdoor heat exchanger; an air outlet of the evaporation fan is opposite to the evaporator and the heat pipe indoor exchanger; and an air outlet of the condensation fan is opposite to the condenser and the heat pipe outdoor exchanger. Compared with the prior art, the double-cold source integrated air-conditioning system has the advantages of compact design, good energy-saving effect and the like, and is easy to control and convenient to overhaul.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to an integrated air-conditioning system with dual cooling sources. Background technique [0002] At present, there are two main types of air-conditioning systems used in base stations and computer rooms: (1) general household cabinet air conditioners or professional base station air conditioners; (2) air-conditioning equipment that uses heat pipe technology or air heat exchangers to make full use of environmental cold sources. All belong to a single refrigeration and air conditioning system. In most areas of China, about 70% of the time can directly use the ambient cold source to cool the room without starting the air conditioner compressor. Only less than 30% of the time is it necessary to run the compressor to keep the room cool. This requires two separate air conditioning systems. This kind of practice mainly has the following defects: (1) Two sets of air-conditioning systems nee...

Problems solved by technology

This kind of practice mainly has the following defects: (1) Two sets of air-conditioning systems need to be purchased separately, which is costly; (2) The two sets of air-conditioning systems generally do not belong to the same company, so they cannot be effectively matched and coordinated, and it is difficult to achieve the expected results; ( 3) Occupies a lot of room space and heavy maintenance tasks

[0003] The patent name is: A dual cold source air conditioning unit (patent number: ZL200920239977) discloses an air conditioning device, which uses three refrigeration circuits to realize the dual cold source air conditioning system, although it also realizes dual cold source refrigeration, However, the cost of the system is relatively high, and the requirements for environmental conditions are relatively high.
