The flowing air absorbs the heat of the compressor, the working conditions of the compressor are improved, the flowing air transfers the heat to the evaporator, the fins are prevented from frosting, the refrigeration liquid evaporation temperature is improved, and electricity energy is saved.
Description
Technical field
The present invention relates to a kind of Teat pump boiler evaporator room structure.
Technical background
Along with development of science and technology and human living standard's raising, the consumption of hot water also increases rapidly, and under the active demand of energy-saving and emission-reduction, Teat pump boiler replaces the big electric heater of power consumption in a large number in the whole society, and the trend of its replacement from strength to strength.
Existing Teat pump boiler places between compressor and the evaporimeter in the outdoor evaporator room and is provided with the next door, and evaporimeter faces the air inlet on the vaporization chamber leg, and Fig. 1 is an existing Teat pump boiler evaporator room work sketch map.The outside air that blower fan when running sucks from air inlet during through the evaporator fin gap with the heat transferred evaporimeter after fan blade air outlet from the evaporimeter leg blow out.
Existing Teat pump boiler evaporator room structure exists two big deficiencies not locate; The one, evaporimeter heat absorption fin is wanted frosting when outside air temperature is low, has increased energy consumption, even can not work.The 2nd, the heat that compressor operating produces is difficult for discharging, deterioration the compressor operating condition, even burn compressor.
Summary of the invention
The objective of the invention is to be prone to frosting and compressor to evaporimeter in the above-mentioned Teat pump boiler evaporator room structure, to be difficult for two places of heat radiation not enough, provides a kind of and can absorb avoid evaporating evaporator room's structure of device frosting of compressor heat.
The technical scheme that the present invention solves its technical problem is; A kind of absorption compressor heat is prevented frosting Teat pump boiler evaporator room; Comprise compressor, blower fan and be located at the evaporimeter that constitutes by band heat-exchange fin refrigerating fluid pipe group between the Compressors and Fans, blower fan, compressor; Evaporimeter all is located at by base plate; Evaporator room's leg is provided with air outlet at the fan blade rear side in the evaporator room that leg and top cover constitute, and it is inboard that compressor is installed on the leg corner, and these leg both sides, place are provided with air inlet.
Fig. 2 is that the present invention absorbs the anti-frosting Teat pump boiler evaporator room of compressor heat work sketch map.Blower fan forward running during three seasons of spring and summer autumn; Outside air is inhaled into the air outlet on the evaporimeter leg; Moving air with heat transferred evaporimeter in the air, takes away when the low temperature moving air after cooling passes through the compressor outer surface on the compressor behind the heat that air inlet blows out from evaporator room's leg during through the evaporator fin gap.
When winter, outside air temperature was lower than design temperature, the temperature detect switch (TDS) closure in the evaporator room made relay coil energising action, and the disjunction of relay normally-closed contact and normally opened contact closure have been switched the capacitor power wiring of fan electromotor makes the blower fan reverse rotation.Capacitor and relay are located in the electrical box.
Fig. 4 is capacitor power wiring automatic switchover control circuit figure.
The blower fan reverse rotation; Cool ambient air sucks from the air inlet on evaporator room's leg; Moving air absorbs the compressor heat through time around the compressor; Moving air after temperature raises with the heat transferred evaporimeter, blows out from evaporator room's air outlet through fan blade when the evaporator fin gap is flow through then.Work sketch map when Fig. 3 is a winter low temperature of the present invention.
The present invention utilizes moving air absorption compressor heat to improve the compressor operating situation, has reduced compressor exhaust temperature and has helped the alternative R22 cold-producing mediums that are about to forbidding of cold-producing medium such as R32.Moving air absorbs the avoid evaporating device fin frosting and improved the cold-producing medium evaporating temperature and reduced energy consumption of compressor heat transferred evaporimeter during winter low temperature.
As preferentially; Said compressor periphery is provided with wind-collecting cover; Wind-collecting cover one end ventilating opening connects the air inlet on evaporator room's leg, and wind-collecting cover other end ventilating opening is open in the evaporator room, and moving air is concentrated the compressor outer surface of flowing through to improve the effect that absorbs the compressor heat by wind-collecting cover.
Described compressor case is provided with fin, strengthens its radiating effect.
The lid of described evaporator room and leg inboard are provided with heat insulating coat, prevent that heat runs off in the low temperature season evaporator room, and the high temperature season external heat is delivered to indoor.

The specific embodiment
Below through specific embodiment and combine accompanying drawing that the present invention is described further.
Spring, summer, autumn are during operation of heat pump; Blower fan (2) also rotates; Outside air from evaporator room's air outlet (6) be inhaled into vaporization chamber after during evaporator fin gap with the heat transferred evaporimeter, the moving air that is cooled passes through then and blows out from evaporator room's air inlet (5) after compressor (4) outer surface absorbs compressor (4) heat.
During winter low temperature; Outside air is reduced to when preestablishing temperature, and the normally opened contact of the inboard temperature detect switch (TDS) (9) that is provided with of evaporator room's air inlet (5) is closed, the power supply of engage relay coil (10); The actuating of relay; Its normally-closed contact (11) breaks off and normally opened contact (12) closure has been switched the power supply wiring of blower fan capacitor (13), makes blower motor (14) reverse rotation.Air is with regard to reverse flow.Capacitor and relay are located in the electrical box (15).
Blower fan conversion steering controling circuit figure when Fig. 4 is a low temperature of the present invention.
After Fig. 3 represented that the blower fan direction of rotation changes, moving air flowed to the duty that thereupon changes.Blower fan reverse rotation outside air absorbed its heat from compressor (4) outer surface of flowing through after the air inlet (5) of evaporimeter leg corner is inhaled into and passes through the evaporator fin gap again with heat transferred evaporimeter (1) when winter, outside air temperature was low, blew out from evaporator room's air outlet (6) through fan blade then.
In order to make concentrated compressor (4) outer surface of flowing through of air improve endothermic effect; In compressor (4) periphery wind-collecting cover (7) is set; Be equipped with ventilating opening (8) on the relative cover wall of wind-collecting cover (7), one of which ventilating opening (8) connects evaporator room's air inlet (5), and another ventilating opening (8) is open in the evaporator room.
Fin is set on compressor (4) outer wall increases heat dissipation capacity.
Set up thermal insulation layer at evaporator room's top cover and leg medial surface, can prevent that external high temperature from importing into summer, can prevent that heat from distributing winter.
