Communication machine room cold-power combination supply system based on LGN (liquefied natural gas) cold energy and heat pump techniques

Abstract

The invention provides a communication machine room cold-power combination supply system based on LGN (liquefied natural gas) cold energy and heat pump techniques, relating to LGN (liquefied natural gas) gas turbine power generation, particularly a cold-power combination supply system for supplying an additional refrigeration energy source to a communication machine room by using LGN cold energy, heat pump and other techniques. The system is characterized by comprising a gas turbine (112), wherein cooling water of the gas turbine (112) and heat of combustible gas exhaust are utilized to drive an absorption refrigeration subsystem; the temperature of cold air (220) is lowered by a tandem traditional precise air conditioner evaporator (118) to obtain cold air (221) which can be sent into the machine room for refrigeration; high-pressure low-temperature LNG (202) enters a condenser (103), and is heated by the heat released by condensing a medium-high-temperature medium-pressure gas-state refrigerant (215) by a condenser (103) to obtain high-pressure medium-temperature gas-state LNG (203); and the cold quantity of the high-pressure low-temperature LNG (202) is utilized to supply an additional refrigeration energy source to the adsorption refrigeration system.

Description

technical field [0001] The invention relates to a combined cooling and power supply system for a communication room using LGN cold energy and heat pump technology. This system can be used to generate power by burning LNG, etc., which can replace the traditional diesel backup power supply in the communication room, and can also partially replace the city power; LNG cold energy can be directly used as a cold source for air-conditioning refrigeration, and the waste heat of combustion can provide energy for air-conditioning refrigeration, reducing precision air-conditioning. the power consumed. The invention can also meet the requirements of high-precision control of the temperature and humidity of the air conditioner and long-term reliable operation in the communication room, and has good compatibility with the existing precision air-conditioning system. Background technique [0002] The requirements for power and air-conditioning refrigeration in the communication room have t...

Problems solved by technology

[0011] In the communication room, due to the immature technology of small gas turbines in my country in the past and the lack of sufficient natural gas supply in most areas, gas turbine technology is rarely used in the communication room, and there is no precedent for using LNG cold energy and combined cooling and power supply at the same time
