Abstract
To solve the problem of air source heat pump defrosting, a kind of new Defrost technology is proposed, i.e.,：One installs a water storage box additional among source pump and heating system, its side is connected with inlet tube and outlet tube and water pump with the import and export of fluorine water heat exchanger, opposite side is connected with inlet tube and outlet tube and water pump with the fan coil or radiator of user, forms two water loops；Two flow through two of the leeward side installation pressure difference meter after fin and take tracheae in place and the air windward of outdoor finned fluorine/air heat exchanger, switch on power, defrosting signal is sent in frosting.
Description
Technical field
Category heating, the building energy saving field of energy-saving and emission-reduction.
Background technology
With electricity heating, heat substitute coal-burning boiler be environmental protection only way, air source heat pump be electric heating technology both
Energy-saving electric power can realize that cooling is warm, a kind of equipment of domestic hot-water's comprehensive function again, but it in the winter time relative air humidity compared with
High period, unfavorable often result in of defrosting are unable to normal use, especially in the end system using fan coil as heating, remove
Frost it is unfavorable often result in user's room temperature too decline it is uncomfortable.Further, since in whole Heating Season, the water capacity of outdoor air is
Change, water capacity great talent can the frosting on the outdoor unit finned tube of heat pump, but source pump is most also along to the time at present
Instruction of the signal in cycle as defrosting, unit also performs defrosting action when causing frostless, expends energy in vain.
To solve the above problems, the present invention proposes a kind of new Defrost technology.
The content of the invention
For solve the problems, such as air-source heat pump hot water in the winter time in wet weather operation can highly effective defrosting, propose a kind of new
Type Defrost technology, it is characterized in that：1st, a water storage box is installed additional between air source heat pump and heating system, its arranged on left and right sides is each
Equipped with a water inlet pipe and outlet pipe, the outlet pipe of wherein side is connected with pump entrance, and the water outlet of water pump is connected to heat pump fluorine/hydro-thermal
The entrance in exchanger water route, the outlet in the heat exchanger water route are connected by pipeline with the water inlet of the water tank side, are formed water and are returned
Road；Water tank opposite side also is provided with inlet tube and outlet tube, and a water pump, outlet and the water tank side of water pump are also equipped with water inlet pipe
Water inlet is connected, and its outlet pipe is connected with the fan coil of user or the water inlet of radiator, the fan coil or radiator
Water outlet is connected to the import of the water pump, forms heating water loop.
2nd, pressure difference meter commercially available Jiang Yitai is mounted in fluorine/air fin tubing heat exchanger outside described air source heat pump room
Surface on, one of pressure difference meter that will be described takes gas tube orifice open in outside atmosphere, and sets windward, and micro-pressure-difference
Another of meter takes gas tube orifice to flow through the leeward side after finned tube bundle installed in air, and the switch signal line of pressure difference meter is connected to electricity
Source.

Embodiment
As shown in figure 1, making by water supply valve, drain valve 14 to be full of water in water system during heat supply in winter, and it is in pressurized tank
In 13 pressure limit, compressor 1 is opened, one outlet of the high-pressure fluorine through four-way valve 2, into fluorine/water heat exchanger 3, this
When water pump 12 open, recirculated water is heated, and the water in water storage box 11 is heated up, if room temperature less than user require, water pump
15 are opened, and heat is sent into fan coil or radiator 16 simultaneously by water pipe, and high pressure gas becomes high pressure liquid, are handed over from fluorine/hydro-thermal
Parallel operation 3 is exported through device for drying and filtering 4, capillary 6, becomes low pressure liquid, enters outdoor fluorine/air heat exchanger by current equalizer 8
9, the thermal change in outdoor air is absorbed into low pressure gas, and compressor 1 is returned after returning to four-way valve 2.
When water capacity is big in outdoor air, meeting frosting, frost layer make on the finned tube bundle of outdoor fluorine/air heat exchanger 9
When outdoor air flows through the finned tube bundle, pressure declines, and making two of pressure difference meter 10 to take in tracheae 10 ', 10 〞 has certain pressure difference
Incoming pressure difference meter, and switch on power, the signal makes four-way valve 2 commutate, and another outlet of high-pressure fluorine through four-way valve 2 enters
Outdoor fluorine/air heat exchanger 9, makes finned tube bundle heat up, and frost layer is melted, and fluorine gas becomes after high pressure liquid through current equalizer 8, dried
Filter 4, non-return valve 5, capillary 7, become low pressure liquid, flow through fluorine/water heat exchanger 3, are absorbed heat from recirculated water and water storage box 11,
Because water storage box 11 has enough heat to release, frost layer can be melted rapidly, so when to fan coil or radiator 16 to
Rooms influence little.
