As can be seen from Figure 1, the total heat exchanger, the need for heat recovery Rotary heat recovery unit price, the solenoid valve a closed heat recovery wheel manufacturers, solenoid valve 2 is turned on, the hot water pump is turned on, from the theoretical analysis partial heat recovery water temperature can be infinitely close to the exhaust temperature of the compressor, in real life, in order to improve the life of heat transfer equipment, hot water temperature no higher than 65 ℃ [1], the general temperature control in hot water about 60 ℃. In this set of system design, pay attention to the heat recovery exchanger area Dingrui optional absorbent core conditioning heat recovery wheel particular specification dedicated low pore size molecular sieve desiccant combination "ROTER 34A". ROTER 34A allows only water molecules By refusing all other pollutants, the result is only to stay in the air from pollutants. High diffusion rate ROTER 34A not only has high heat recovery unit selectively, while the high diffusivity and selectivity together. Our fans are gas compression and gas transportation machinery habits short, commonly referred to fans, including fans, blowers, wind turbines. Gas compression and gas delivery rotating machinery is to be converted to mechanical energy and kinetic energy of gas pressure, and gas transfer out of the machinery. The main structural components of the fan impeller, housing, air inlet, brackets, motors, pulleys, couplings, muffler, transmission parts (bearings) and so on. _ Full heat recovery heat and heat recovery _ Dingrui air conditioning (certified merchants) by Wu Cheng Ding Rui Air Conditioning Equipment Co., Ltd.
