Description
Technical field
The present invention relates to a kind of air-source water heater with defrosting snaking function.
Background technology
Air-source water heater, also referred to as " air source hot pump water heater ", is to use heat pump operation principle from sky
Gas absorbs heat and manufactures the device of hot water.Air-source water heater by allow coolant constantly complete evaporation,
Compress, condense, throttle and the thermodynamic cycle process of re-evaporation, the heat in environment is transferred to
In water.The power consumption of air-source water heater generally only has 1/4th of electric heater, and need not
As solar water heater, rely on sunlight adopt heat, owing to the work of air-source water heater is to pass through coolant
Heat exchange realize, therefore contact with water also without electrical heating elements, also would not as electric heater that
There is electric leakage, the potential safety hazard of dry combustion method in sample, blast and the danger of poisoning does not the most occur, uses
Fool proof, simultaneously the most very environmental protection, generally using the life-span can reach 15 to 20 years.
The heat of thermal medium is transferred in water by heat exchanger tube by air-source water heater, existing heat exchanger tube one
Planting is external heat exchanger pipe, will be wrapped in the periphery of water tank to add the water in water tank by heat exchanger tube
Heat, this mode of heating heat exchange is insufficient, and the water firing rate in the middle part of water tank is relatively slow, and is placed in outside
Heat exchanger tube thermal loss relatively big, energy consumption is the highest；Another kind is built-in heat exchanger tube, by dual layer discs
Pipe is built in water tank and heats water, and duplex coil considerably increases heat exchange area, heat transfer efficiency
Height, energy consumption is low, and the heat exchanger tube of this duplex coil is placed in water easy fouling for a long time, and because of dual layer discs
The structure of pipe not incrustation scale outside easy cleaning heat exchanger tube, along with the increasing of incrustation scale on heat exchanger tube outer wall, changes
The most worse and worse, energy consumption is also gradually increased the heat transfer effect of heat pipe.
Vaporizer is a critical component of the refrigeration system built based on air source heat pump, heat pump
The surface frosting of air side vaporizer can block fin clearance (air duct of vaporizer), reduces wing
Air mass flow between sheet, increases the thermal resistance of vaporizer, reduces the heat exchange efficiency of vaporizer.
Vaporizer mainly uses the Defrost method of heating defrosting at present, including the reverse hot gas defrosting of cross valve
And electric heated defrosting, when the frost of deposition is abundant on vaporizer, just open defrosting function.Air-conditioning
When heating in the winter time, heating defrost multistage compressor stops indoor heating, causes temperature to decline, shadow
Ring indoor comfort degree；And air-cooler, refrigerator are when heating defrost, the article of storage are because of by temperature
The recurrent fluctuations impact of degree, brings the decline of storage quality.
Summary of the invention
For solving above technical deficiency, the invention provides a kind of sky with defrosting snaking function
Gas energy water heater, it is possible to remove the incrustation scale on heat exchanger tube in time, improve heat exchange efficiency.
The present invention is achieved by the following measures:
A kind of air-source water heater with defrosting snaking function of the present invention, including compressor and water tank,

Being provided with valve, restricting element, vaporizer and gas-liquid separator on road, described tank top is detachable
Connect and have case lid, in water tank, be vertically arranged with the strip between heat exchange coil and water tank medial wall
Scraper plate, two sides of described scraper plate are pressed close to heat exchange coil lateral wall and water tank medial wall respectively, are scraped
The top of plate is connected by cross bar the sleeve passed from case lid center, and described lower cartridge is by sealing
Bearing is rotationally connected with case lid, is cased with driven gear outside upper cartridge, and described driven gear is engaged with
Driving gear, is provided with the motor of drive connection driving gear, described medium outside described water tank
It is connected with heat exchange coil in circulation line is through sleeve and through case lid；Described vaporizer side is arranged
Having ultrasonic transducer, described ultrasonic transducer connects has supersonic generator, described ultrasound wave to send out
Raw device connects controller, and described controller connects frost thickness sensor and temperature sensor.
Above-mentioned water tank bottom is provided with the bottom of circular arc, and bottom is provided centrally with sewage draining exit, described blowdown
Blowoff valve it is provided with at Kou.
It is provided with hairbrush on the dual-side of above-mentioned scraper plate.
Some through holes it are provided with on above-mentioned scraper plate.
The invention has the beneficial effects as follows: can heat exchanging coil surface clear up at any time, it is not necessary to tear open
Unloading water tank, simple to operate, disposal costs are low, it is possible to dispose the incrustation scale on heat exchange coil in time, keep away
The reduction of heat exchange efficiency and the increase of energy consumption are exempted from.The present invention use that power ultrasonic caused by a narrow margin,
High frequency, high acceleration mechanical vibration defrost, and improve defrosting, the effect of suppression frosting, and reduce
The energy expenditure of defrosting, it is ensured that the safety of ultrasonic system.
