Description
Technical field
The utility model relates to air source heat pump hot water device, further is meant by heating the hot-water supply device that compressor, water-cooled condenser, air-cooled condenser, expansion valve, evaporimeter connect to form.
Background technology
In the prior art, people's life or the needed hot water great majority of production process still use the fuel supply by boiler.Because boiler thermal output is not high, fuel combustion is incomplete, not only wastes a large amount of energy but also cause environmental pollution.Adopt general heat pump techniques to produce hot water, if low-phase energy will adopt underground water, surface water, waste water etc., these low-phase energies are not easy to obtain sometimes; Though adopt air inexhaustible and desirable everywhere as the low-phase energy energy of heat pump, also be subjected to the restriction of temperature height, air humidity, heat pump performance is affected when too cold, too hot, even can't start; Too wet then evaporimeter exhaust outlet may frosting, stops up ventilating opening and heat pump can't be moved.
The utility model content
The technical problems to be solved in the utility model is, defective at the prior art existence, propose a kind of air source twin-stage recovery type heat water-heating device, it is a kind of high-efficiency and energy-saving type air source heat pump hot water device that causes its heating performance to worsen affected by environment hardly.
Technical solution of the present utility model is, described air source twin-stage recovery type heat hot water apparatus comprises and heats compressor, water-cooled condenser, air-cooled condenser, heating power expansion valve, evaporimeter and blower fan, its design feature is, the described working medium output that heats compressor is communicated with the working medium input of described water-cooled condenser and the working medium output of this water-cooled condenser is connected in series described air-cooled condenser successively, heating power expansion valve, evaporimeter, the working medium output of described evaporimeter joins with the described return-air joint that heats compressor, described water-cooled condenser is provided with the water inlet pipe and the outlet pipe of hot water circuit heating, blower fan is positioned at described air-cooled condenser one side, and evaporimeter is positioned at the downwind side of described air-cooled condenser.
Make below in conjunction with accompanying drawing and to further specify.
Referring to Fig. 1, the utility model comprises and heats compressor 1, water-cooled condenser 2, air-cooled condenser 3, heating power expansion valve 4, evaporimeter 5 and blower fan 6, its design feature is, the described working medium output that heats compressor 1 is communicated with the working medium input of described water-cooled condenser 2 and the working medium output of this water-cooled condenser 2 is connected in series described air-cooled condenser 3 successively, heating power expansion valve 4, evaporimeter 5, the working medium output of described evaporimeter 5 joins with the described return-air joint that heats compressor 1, described water-cooled condenser 2 is provided with the water inlet pipe 7 and the outlet pipe 8 of hot water circuit heating, described blower fan 6 is positioned at described air-cooled condenser 3 one sides, and evaporimeter is positioned at the downwind side (being the air draught that evaporimeter accepts to blow over air-cooled condenser 3) of described air-cooled condenser 3.
Operation principle of the present utility model is (referring to Fig. 1), and the high-temperature exhaust air that heats compressor 1 at first carries out heat exchange with water-cooled condenser 2, and water-cooled condenser 2 will obtain a large amount of heats and to produce the hot water of higher temperature for people to use, and this is first order recuperation of heat; High-temperature exhaust air (working medium) has been emitted whole overheated heat and partial condensation heat after absorbing heat through described water-cooled condenser 2, entering the air stream exchange that a large amount of heat in air-cooled condenser 3 backs is produced by blower fan 6, make gaseous state heat the working medium total condensation and become liquid, these liquid state heat working medium and enter evaporimeter 5 through heating power expansion valve 4 step-downs vaporization then, heat in the waste hot gas that absorption air-cooled condenser 3 is discharged, make liquid state heat working medium and vaporize fully, return and heat compressor 1 compression, finish heating circulation; The used heat that evaporimeter 5 absorbs air-cooled condenser 3 is the secondary recuperation of heat of this device.
In order to make evaporimeter 5 be recovered to the waste-gas heat that air-cooled condenser 3 is discharged, evaporimeter 5 should be installed in the downstream (being downwind side) of air-cooled condenser 3 air flow processs, can arrange near air-cooled condenser 3, makes the structure of device very compact.
As known from the above, the utility model is a kind of air source twin-stage recovery type heat hot water apparatus, it utilizes condenser and evaporimeter to realize heat recovery function simultaneously, can save operating cost to greatest extent, and enlarged the range of application of heat pump, be a kind of high-efficiency and energy-saving type air source heat pump hot water device that causes heating performance to worsen affected by environment hardly.
