Abstract
The heat pump type air-cooled air conditioner utilizing the afterheat of compressor includes mainly refrigerant loop comprising compressor, outdoor heat exchanger, throttle unit and indoor heat exchanger; and outdoor blower capable of changing its rotation direction in winter. In winter and while the room is heated, the outdoor blower rotates in reverse direction, so that air from outdoor flows first through the compressor to exchange heat with the compressor casing to raise temperature and then through outdoor heat exchanger to exchange heat with refrigerant. The present invention recovers the heat of compressor to raise the air intake temperature, improve the low temperature working performance of the air conditioner and the winter operation performance of the air conditioner.
Description
Technical field:
The present invention relates to the air-cooled air-conditioner of a kind of pump type heat, relate in particular to a kind of heat of compressor that utilizes and improve the air-cooled air-conditioner of the pump type heat of heating capacity under the worst cold case, belong to the Refrigeration ﹠ Air-Conditioning technical field.
Background technology:
Heat pump type air conditioner is used for refrigeration summer, be used to heat winter, is a kind of energy-conservation heat-supplying mode.Yet when environment temperature was lower than 5 ℃, the easy frosting of outdoor evaporimeter of Wind-cooling type air-conditioner caused heat exchange property to worsen.So, after air-conditioner moves a period of time by the mode of heating, will switch to refrigeration modes by four-way change-over valve and defrost.After the commutation, original outdoor heat exchanger has become condenser by evaporimeter, by the cold-producing medium heat release heat exchanging device defrosting of high temperature.Simultaneously, original indoor heat exchanger has become evaporimeter by condenser, the heat in the absorption chamber.
Owing to there is the part heat to pass through compressor case in (1) compression process directly to environmental emission; (2) air-conditioner can cause thermal loss and increase consumption of compressor when Defrost operation, and this has restricted the coefficient of performance when air-conditioner moves in the winter time to a great extent, when serious even cause the heating efficiency of air-conditioner to be lower than electrical heating and no longer energy-conservation.
Summary of the invention:
Be deficiency and the defective that overcomes prior art, the present invention's design provides a kind of heat of compressor that utilizes to improve the air-cooled air-conditioner of the pump type heat of heating capacity under the worst cold case, mainly comprise the refrigerant loop of forming by compressor, outdoor heat exchanger, throttling arrangement and indoor heat exchanger, and the off-premises station blower fan that can change direction of rotation in the winter time under the operating mode.
Air-conditioner is when summer operation, and outdoor heat exchanger plays the effect of condenser.Under the effect of off-premises station blower fan, air is earlier through outdoor heat exchanger, carries out heat exchange with wherein cold-producing medium; When the part air is through compressor then compressor is cooled off the back and discharge, the remainder air is directly discharged.
When air-conditioner moved in the winter time, outdoor heat exchanger played the effect of evaporimeter.The reverse rotation of off-premises station blower fan.Under the effect of off-premises station blower fan, the part air earlier through the casing of compressor, carries out heat exchange, passes through outdoor heat exchanger more then with after the remainder air mixes, and carries out discharging after the heat exchange with wherein cold-producing medium.
The present invention has significant advantage and good effect.At first, the present invention has reclaimed compressor and has discharged heat to environment originally when air conditioner heat-production moves, help improving the coefficient of performance in winter of air-conditioner.Secondly, the EAT of evaporimeter is higher than environment temperature because of being heated, and makes the environment temperature of evaporator non-frost operation can be lower than 5 ℃.Even if finish frost under lower environment temperature, defrosting cycle also can prolong, and this helps improving the coefficient of performance in winter of air-conditioner equally.
Description of drawings:
Fig. 1 is the principle schematic of the air-cooled air-conditioner of pump type heat of the present invention.
Among the figure, 1 is compressor, and 2 is outdoor heat exchanger, and 3 is throttling arrangement, and 4 is indoor heat exchanger, and 5 is the off-premises station blower fan, and 6 is the casing of off-premises station.
Among the figure, the air flow when solid arrow is represented summer condition, the air flow when dotted arrow is represented winter condition.
The specific embodiment:
Below in conjunction with accompanying drawing technical scheme of the present invention is further described.
As shown in Figure 1, the present invention mainly comprises the casing 6 of compressor 1, outdoor heat exchanger 2, throttling arrangement 3, indoor heat exchanger 4, off-premises station blower fan 5, off-premises station.Air-conditioner is when summer operation, the import of the blast pipe junction chamber external heat exchanger 2 of compressor 1, the outlet of outdoor heat exchanger 2 connects the import of throttling arrangement 3, and the outlet of throttling arrangement 3 connects the import of indoor heat exchanger 4, and the outlet of indoor heat exchanger 4 connects the air intake duct of compressor 1; When air-conditioner moves in the winter time, the blast pipe of compressor 1 connects the import of indoor heat exchanger 4, the import of the import of the outlet connection throttling arrangement 3 of indoor heat exchanger 4, the outlet junction chamber external heat exchanger 2 of throttling arrangement 3, the outlet of outdoor heat exchanger 2 connects the air intake duct of compressor 1.Off-premises station blower fan 5, outdoor heat exchanger 2, compressor 1 all are included in the casing 6 of off-premises station.
Air-conditioner is when summer operation, and outdoor heat exchanger 2 plays the effect of condenser.Under the effect of off-premises station blower fan 5, air is earlier through outdoor heat exchanger 2, carries out heat exchange with wherein cold-producing medium; When the part air is through compressor 1 then compressor 1 is cooled off the back and discharge, the remainder air is directly discharged.
When air-conditioner moved in the winter time, outdoor heat exchanger 2 played the effect of evaporimeter.5 reverse rotations of off-premises station blower fan.Under the effect of off-premises station blower fan 5, the part air earlier through the casing of compressor 1, carries out heat exchange, passes through outdoor heat exchanger 2 more then with after the remainder air mixes, and carries out discharging after the heat exchange with wherein cold-producing medium.
In addition, for the air that makes more shares participates in and the heat exchange of compressor case, can on compressor case, install fin additional.
