Energy-saving type air conditioner in machine room

Abstract

The invention discloses an energy-saving type air conditioner in a machine room. The energy-saving type air conditioner comprises a water tank, a circulating pump, an electric three-way valve, a refrigerating system, an air cooling heat exchanger, a heat exchange coil pipe, an electronic control system and an indoor circulating fan. An outlet of the water tank is connected with the circulating pump to be connected with the inlet end of the electric three-way valve, one outlet end of the electric three-way valve is connected with the inlet end of the refrigerating system, the other outlet end of the electric three-way valve is connected with the air cooling heat exchanger to be joined with the outlet end of the refrigerating system, and then the other outlet end of the electric three-way valve is connected with the heat exchange coil pipe to be connected with an inlet of the water tank. Reliable running of the air conditioner is achieved; meanwhile, the energy consumption is reduced, the service life is prolonged, and the air conditioner is not limited by the occasion with the totally-closed machine room, is suitable for the machine room environments which include telecommunication, computers, data switching centers, network centers and the like and require high-reliability and full-time and full-working-condition heat dissipation and is used for reducing the temperature of the environment in the machine room to meet the device running requirement.

Description

technical field [0001] The invention relates to the field of environment control equipment, in particular to an energy-saving computer room air conditioner. Background technique [0002] At present, electronic equipment in computer rooms such as data exchange centers and network centers will generate a lot of heat when they are working. As a relatively closed environment, if the heat inside the computer room cannot be dissipated in time, the electronic equipment will not operate normally. Therefore, air-conditioning equipment is needed to control the ambient temperature of the computer room. [0003] The electronic equipment in the computer room works 24 hours a day, so the air conditioner must work normally around the clock, which puts high demands on the low-temperature refrigeration of the air conditioner: if the ambient temperature is very low, there will be insufficient pressure difference on both sides of the expansion valve to drive the refrigerant The flow of a...

Problems solved by technology

Although these measures have solved the problem of normal operation of air-conditioning equipment, since all compressors are used for refrigeration, the energy consumption is relatively large, and the service life of the compressors is also reduced.

[0004] When the ambient temperature is very low, some manufacturers adopt the form of fresh air to directly use ambient cold air to cool down the interior of the computer room. This method is energy-saving and reliable, but it is limited in some fully enclosed computer room applications
