Description

Two-way pressure convection of heat wind defrosting heat pump
One, technical field
The present invention relates to a kind of electrical equipment, the heat pump of a kind of two-way pressure convection of heat wind defrosting.
Two, background technology
Air source heat pump circulation on the market heats work, and the coolant in outer machine heat exchanger is less than zero degree, in air Steam is being frozen on heat exchanger through heat exchanger, the easy frosting of heat exchanger.Once the full frost of heat exchanger surface knot cannot enter Row heat convection, heat exchange efficiency, by degradation, needs to clear up heat exchanger surface frost by intermittent defrosting, defrosting Module the most easily breaks down, and even defrosting has been completed, again without terminating defrosting in time.
Three, summary of the invention
This utility model is for above-mentioned technical problem, it is necessary to provide a kind of two-way pressure convection of heat wind defrosting heat pump.
Technical scheme:
A kind of two-way pressure convection of heat wind defrosting heat pump, including vaporizer, condenser, fan, controller, gas-liquid separation Device, compressor, fluid reservoir, filter, expansion valve, filter screen, shell, by vaporizer, condenser, gas-liquid separator, compressor, storage Flow container, filter, expansion valve connects, and installs in the enclosure, and fan is arranged on cover top portion, and filter screen is arranged on shell side, control Device processed is installed in the enclosure, and fan is controlled to open by controller.
This two-way pressure convection of heat wind defrosting heat pump is owing to using two-way pressure convection fan, when working medium is compressed into condenser During heating, starting fan suction cold air is to outdoor heat radiation, when evaporimeter frosting, controls fan and reversely rotates, outdoor suck Hot blast, reduces heat convection thermal resistance, defrosts to vaporizer, simplifies defrosting process, reduces heat pump energy consumption, has saved and run into This.
Four, accompanying drawing explanation
Fig. 1 is the principle schematic of two-way pressure convection of heat wind defrosting heat pump of the present utility model.
1 is vaporizer, and 2 is condenser, and 3 is fan, and 4 is controller, and 5 is gas-liquid separator, and 6 is compressor, and 7 is liquid storage Tank, 8 is filter, and 9 is expansion valve, and 10 is filter screen, and 11 is shell.
Following detailed description of the invention will further illustrate this utility model in conjunction with above-mentioned accompanying drawing.
Five, detailed description of the invention
A kind of two-way pressure convection of heat wind defrosting heat pump, it is by vaporizer 1, condenser 2, gas-liquid separator 5, compressor 6, Fluid reservoir 7, filter 8, expansion valve 9 connects, and is arranged in shell 11, and fan is arranged on cover top portion, outside filter screen 10 is arranged on Shell 11 side, controller 4 is installed in the enclosure, and fan 3 is controlled to open by controller 4.After startup, fans in operation 3, outdoor air Carrying out heat exchange by vaporizer 1, outside the air after cooling is by fan 3 discharge chamber, new wind filters from filter screen 10 and sucks, meanwhile, Working medium within vaporizer 1 is inhaled into compressor 6 by fluid reservoir 7 vaporization of absorbing heat, and compressor 6 is by this low pressure working fluid gas pressure Shorten high temperature into, gases at high pressure send into condenser 2, and condenser 2 is cooled directly with water, and working medium is cooled into liquid, the expanded valve of this liquid 9 Again flowing into vaporizer 1 after throttling cooling, such iterative cycles works, and the heat energy in air is constantly delivered in water, makes water temperature Gradually rise.When vaporizer 1 forms frosting, starting fan 3 reversed operation, sucked by outdoor air, hot blast is from filter screen 10 mistake Filter is discharged, and improves forced convertion effect, hot blast is passed to evaporator surface, reaches the purpose effectively defrosted.
