Description
Technical field
The utility model belongs to Waste Heat Recovery technical field, is specifically related to a kind of waste heat recovery plant of water resource heat pump.
Background technology
Water source heat pump technology is more a kind of energy-saving and environmental protection, the green energy resource of current application, it is to utilize the solar energy that absorbs in earth surface shallow-layer water source and geothermal energy and the low temperature Lowlevel thermal energy resource that forms, adopt heat pump principle, by a small amount of high-order electric energy input, realize a kind of technology that Lowlevel thermal energy shifts to high level heat.Energy-saving and emission-reduction are fundamental state policies of China, can be again enterprise self create beneficial result when being more than applied in energy-saving and emission-reduction.
The refrigeration mode of general water resource heat pump mode of operation is: the refrigerant gas of HTHP out enters condenser from compressor, and cold-producing medium is emitted heat in cooling water, forms high temperature high pressure liquid, and coolant water temperature is raise; Cold-producing medium is expanding into low-temp low-pressure liquid through expansion valve, enter the heat in evaporimeter absorption refrigerating water, flash to low-pressure steam, and freezing temperature is reduced, low pressure refrigerant vapor enters again compressor compresses and becomes high temperature and high pressure gas, so circulates in the continuous cryogenic freezing water that obtains in evaporimeter.In above-mentioned refrigeration mode, the refrigerant gas of HTHP directly enters condenser out to carry out heat release and forms high temperature high pressure liquid from compressor, and the gas in this process changes into this part heat of liquid and fails to be fully used.
Utility model content
The purpose of this utility model is to provide a kind of waste heat recovery plant of water resource heat pump.
For achieving the above object, the technical scheme that the utility model is taked is as follows:
A kind of waste heat recovery plant of water resource heat pump, comprise the compressor, condenser, expansion valve, the evaporimeter that are in turn connected to form closed circuit, its improvements are: between compressor, condenser, have additional tubular heat exchanger, the import of tubular heat exchanger is connected with low-temperature water heating water pot by hot water circulating pump, outlet is connected with heat preservation hot water tank, and heat preservation hot water tank is connected to dehumidifier or the domestic hot-water's water system in assembled air-conditioner unit.
The import of condenser is connected with cooling water water pot by cooling water circulating pump; The import of evaporimeter is connected with chilled water water pot by chilled water circulating pump.
Conventionally in refrigeration mode, the refrigerant gas of HTHP directly enters condenser out to carry out heat release and forms high temperature high pressure liquid from compressor.Change into this part heat of liquid in order to make full use of gas in this process, the utility model was set up tubular heat exchanger at the refrigerant gas of HTHP before compressor out enters condenser, the heat that gaseous refrigerant is taken away by outer row's cooling water is recycled by tubular heat exchanger, set up heat preservation hot water tank simultaneously, so just obtain the hot water that temperature can reach 52 DEG C of left and right, this hot water not only can need for technique, as: the dehumidifier of dust proof workshop combined type air-supply in summer unit, and can live for worker, as have a bath, wash clothes etc., equipment investment and the daily fuel consumption of fire coal or electric boiler are saved.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of waste heat recovery plant of water resource heat pump, comprises the compressor 1, condenser 4, expansion valve 3, the evaporimeter 2 that are in turn connected to form closed circuit, and the import of condenser 4 is connected with cooling water water pot 10 by cooling water circulating pump 6; The import of evaporimeter 2 is connected with chilled water water pot 11 by chilled water circulating pump 5, between compressor 1, condenser 4, have additional tubular heat exchanger 7, the import of tubular heat exchanger 7 is connected with 30 DEG C of left and right low-temperature water heating water pots 12 by hot water circulating pump 8, outlet is connected with heat preservation hot water tank 9, and heat preservation hot water tank 9 is connected to dehumidifier or the domestic hot-water's water system in assembled air-conditioner unit.
When refrigeration, refrigerant gas at HTHP was set up tubular heat exchanger before compressor 1 out enters condenser 4, the heat that gaseous refrigerant is taken away by outer row's cooling water is recycled by tubular heat exchanger 7, so just obtain the hot water that temperature can reach 52 DEG C of left and right, this hot water not only can be delivered to the dehumidifier in assembled air-conditioner unit, needs, and can deliver to domestic hot-water's water system for technique, for worker's life, as have a bath, wash clothes etc.In the time that this hot water is connected to the dehumidifier in assembled air-conditioner unit, the former power that needs of this equipment is 80KW, uses after this hot water recovery system, and can save electric weight every day is 1920KW, according to 0.7 yuan of calculating of every degree electricity, can save 1344 yuan every day; Monthly calculated according to 30 days, monthly can save 40320 yuan; In the time that this hot water is connected to domestic hot-water's water system, for hot water every day of living, with 10 tons, hot water temperature is 52 DEG C, and every day, consumption of calorie was 10*1.0*(52-20)=320KW, according to 0.7 yuan of calculating of every degree electricity, can save 224 yuan every day; Monthly calculated according to 30 days, monthly can save 6720 yuan.Below can save altogether 47040 yuan, can save in year and consume 564480 yuan.
