Description

A kind of automatic waste heat recovery water heater for being embedded in refrigeration system
Technical field
Patent of the present invention is related to a kind of waste heat recovery water heater, and particularly a kind of insertion type is vented installed in refrigeration system Among pipeline, the water heater of the recovery exhaust waste heat of Automatic Control.
Background technology
In general refrigeration system is by parts such as compressor, condenser, restricting element, evaporators and fills in system Refrigerant forms.Liquid refrigerant absorbs in evaporator is cooled externally the heat of vaporization of object into refrigerant vapour, gas HTHP is compressed into by compressor suction(Temperature is generally at 80 ~ 100 degrees Celsius)Superheated steam, to outside in condenser Function of environment heat emission, liquid is condensed into, enters evaporator through restricting element throttling, so week begins reciprocal.The heat bag of refrigeration system discharge The heat of evaporator absorption is contained and the power consumption of compressor, these heats passes through the shapes such as air-cooled, water-cooled, transpiration-cooled The condenser of formula is discharged in atmospheric environment in vain, is not used.
The content of the invention
Present invention aims at provide a kind of positive displacement water heat exchanger simple in construction, safe and reliable, efficient, installation On the discharge duct of refrigeration system, the partial condensation heat extraction of refrigeration system can be reclaimed automatically, the energy, which is converted into, to be made Hot water.
In order to achieve the above object, the technical solution adopted by the present invention is:It is a kind of to be embedded in the automatic useless of refrigeration system Heat-recovery water heater, it is characterised in that:Including staving, heat exchanger, electric three passes reversal valve and check (non-return) valve, staving upper and lower part Not She You hot water outlet and running water inlet, the interface for placing temperature sensor is provided with the middle part of staving, be provided with staving one with On heat exchanger, heat exchanger extended to outside staving into and out of tube connection ports, and heat exchanger inlet pipe is communicated to electric three passes reversal valve One outlet, the inlet communication of electric three passes reversal valve is to the exhaust outlet of compressor of refrigeration system, and the connection of heat exchanger outlet pipe is to end Inverse valve, another outlet of electric three passes reversal valve and the outlet of check (non-return) valve converge the condenser inlet for being communicated to refrigeration system.
Staving makes enclosed construction using water-fast corrosion-resistant metal materials, and staving foams built with anode stub, staving outside There is adiabator layer.
Heat exchanger is the heat exchanger that metal tube turns to spiral disc form of tubes, and heat exchange pipe external surface is light pipe or coiling rib Piece;Or heat exchanger is plate type heat exchanger, the welding of plate two-by-two and middle formation of plate type heat exchanger are adapted to the close of refrigerant flowing Closed walk, plate are band excess metal thin plate.
Electric three passes reversal valve is controlled by temperature sensor.
Staving is provided with the interface for preventing auxiliary electrical heater.
Staving bottom is provided with sewage draining exit.
The course of work of the present invention:The compressor air-discharging outlet connection electric three passes reversal valve import of refrigeration system, threeway The one outlet of reversal valve connects the heat exchanger import of heat regenerator of the present invention, and heat exchanger exit is connected to check (non-return) valve, Ran Hou Another outlet with three-way diverter valve converges, and is connected to the import of condenser.Temperature sensor or via monitoring control devices Hot water temperature inside heat regenerator, if less than the temperature of setting, import and the heat regenerator mouth phase of electric three passes reversal valve It is logical, and it is obstructed with condenser mouth, and compressor air-discharging flows through three-way diverter valve and enters heat regenerator, and heat is passed through in heat regenerator The heat exchanger release feedwater in portion, the refrigerant gas after cooling are condensed into liquid by check (non-return) valve into condenser.When water temperature reaches To the temperature of setting, then electric three passes reversal valve carries out commutation switching, and its import communicates with condenser side, and with heat regenerator mouth Obstructed, compressor air-discharging flows through three-way diverter valve and condensed into condenser, and due to there is check (non-return) valve, refrigerant may not flow into recuperation of heat Device.
The beneficial effect that the present invention reaches is:1)The partially recycled used heat that refrigeration system is discharged to air is hot water, heat Water can be used for washing tableware, do the antifreeze heating of cold storage floor, as domestic water or floor heating heat hot water, turn waste into wealth, save About energy resource consumption.2)Condensation area is increased during recuperation of heat, helps to reduce refrigeration system power consumption.3)Effluent temperature constancy.4) There is certain retention volume, can be concentrated use on night storage heating, daytime;5)Such as city tap-water pressure enough, without increasing additional water Pump can supply water.6)Automatic Control water temperature, without artificial switching;7)This waste heat recovery water heater is established one's own system, to existing The refrigeration system transformation of standard is simple and easy, need to only disconnect the blast pipe of compressor to condenser, it is possible to which the embedded heat is returned Device is received, and does not influence original performance of refrigerant systems.8)To large supermarket, freezer, food processing factory, multiple refrigeration systems be present System, the hot water of the heat regenerator of each system can not be interfere with each other with used in parallel.
