Description
The invention belongs to low-grade energy comprehensive utilization system.
A large amount of heat energy losses is arranged in the power transformer running, come out with heat energy formation, utilize the transmission of air or water to abandon it as used heat by transformer oil.Why this energy is lost, and is that mainly the grade of this energy is low, does not have the value of directly utilizing.
Purpose of the present invention is intended to make full use of the energy consumption of power transformer, by improving its heat energy grade, makes it to have the value of direct utilization.
Purpose of the present invention is achieved through the following technical solutions: the power transformer energy consumption utilization system is made up of evaporimeter, condenser, compressor, expansion valve and corresponding mechanical and electrical protection control device, wherein also comprises power transformer, cooler, collecting-tank and heating equipment, air-conditioning equipment etc.Native system mainly is made of four closed circuits:
1. electric power transformer oil closed circuit, transformer average oil temperature, winter is generally at 25～30 ℃, squeeze into the evaporimeter tube bank by oil-immersed pump, with the heat transferred evaporimeter working medium (R142) in the oil, after the working medium heat absorption, transformer ℃ is flowed back in oily temperature drop to 15～20, the heat that absorbs transformer energy consumption again and come out, reciprocation cycle.
2. working medium closed circuit, working medium is accepted in the oil behind the heat in the evaporimeter, be evaporated to gas phase by liquid phase, be loaded with the compressed machine supercharging intensification of a large amount of gas phase working medium and enter condenser, with the intrafascicular water of contained heat transferred condenser tube, water temperature is risen to about 55 ℃, working medium is cooled to liquid phase, flow back to evaporimeter through the expansion valve step-down, finish the working medium circulation
3. hot water circulation loop.Be the water about 55 ℃ with heating up in the condenser, beat to the building caliduct that the water reflux condenser after the heat radiation absorbs the heat repetitive cycling in the working medium once more by water pump.
4. cold water closed circuit.Running water in the freezing water apparatus makes temperature reduce by 7～8 ℃ the working medium (R142) in the heat transferred tube bank, and the water after the cooling is beaten to the fan coil in air-conditioning place through water pump, realizes air-conditioning.Current in the absorption air behind the heat return freezing water apparatus, finish a circulation.Working medium (R142) heat absorption back in the freezing water apparatus tube bank becomes gas phase by liquid phase, compressed machine enters condenser after boosting and heating up, water to 40～50 of heating in the condenser water circuit ℃, hot water are beaten to the cooler cooling by water pump and are flowed into collecting-tank, for recycling once more.Hot water also can be supplied domestic water.
The coupling system schematic diagram is further described formation of the present invention.
