As shown in Figure 1, the utility model is a kind of heat recovery system for air compressor for air-conditioning heating system.
Air-conditioning heating system 200 comprises air-cooled heat-pump air-conditioner group 21 and end air-conditioning box unit 16, air-cooled heat-pump air-conditioner group 21 is connected with end air-conditioning box unit 16 by air-conditioning water pipe 18, end air-conditioning box unit 16 is connected with air-cooled heat-pump air-conditioner group 21 by air-conditioning return pipe 23, and air conditioner water recycle pump 22 and swelling water tank 17 are installed on air-conditioning return pipe 23.Swelling water tank 17 is used for regulating the water yield in air-conditioning return pipe 23.
Heat recovery system for air compressor 100 comprises oil water heat exchange device 1 and water water-to-water heat exchanger 5.
The oily side of oil water heat exchange device 1 is connected with the oil cooler of air compressor, and the water side of oil water heat exchange device 1 and the high temperature side of water water-to-water heat exchanger 5 and the first circulating water pump 4 form high-temperature water loop.A port of oil water heat exchange device 1 water side is connected with the water inlet port of water water-to-water heat exchanger 5 high temperature sides by the first water pipe 3, the water outlet port of water water-to-water heat exchanger 5 high temperature sides is connected with another port of oil water heat exchange device 1 water side by the first return pipe 6, and the first circulating water pump 4 is arranged on the first return pipe 6.
In the part of the first return pipe 6 near oil water heat exchange device 1 water side, the 3rd warming 2 is installed.The 3rd warming 2 is used for judging whether the running state of air compressor has surplus heat and can utilize: if the temperature of the 3rd warming 2 lower than 80 degrees Celsius, illustrates that air compressor is not in operation, or load factor is too low, without the Economy of recycling; If the temperature of the 3rd warming 2 is greater than or equal to 80 degrees Celsius, explanation now has surplus heat and can utilize, and at this moment the first circulating water pump 4 is opened, and heat is carried out to circulating transfer.
On the first return pipe 6, enclosed expansion drum 7 is also installed, is used for regulating the water yield in the first return pipe 6.
Two ports of water water-to-water heat exchanger 5 low temperature sides are connected with the air-conditioning return pipe 23 of air-conditioning heating system by pipeline respectively; On the pipeline of water water-to-water heat exchanger 5, be provided with the second circulating water pump 9.
The water inlet port of water water-to-water heat exchanger 5 low temperature sides is connected with air-conditioning return pipe 23 by the second return pipe 12, and its water outlet port is connected with air-conditioning return pipe 23 by the second water pipe 8, and the second circulating water pump 9 is arranged on the second return pipe 12.
In the part of the second water pipe 8 near air-conditioning return pipe 23, the second warming 13 is installed.The second warming 13 is for monitoring heat recovery in use, actual in the hot water backwater's temperature reclaiming, and whether the running state that is used for monitoring heat recovery system is normal, thereby controls the second circulating water pump 9.
