Description
The present invention relates to a kind of air-conditioner, and relate more particularly to a kind of heat pump type air conditioner.
Usually, pump type heat (heat pump type) air-conditioner produces from the heat of outdoor heat exchanger so that the interior space heats up by indoor heat exchanger emission, and off and on recycled back refrigerant to remove the frost on the outdoor heat exchanger.
A kind of air-conditioner like this is shown in Fig. 1, as shown in the figure, heat pump type air conditioner be provided with one be used for the conversion cryogen flow to flow to reversal valve 13.Flow to reversal valve 13 and be provided with four valve port P1, P2, P3 and P4.In heating mode, the first valve port P1 that flows to reversal valve 13 that is connected to compressor 11 outlet sides is communicated with the second valve port P2 that is connected to indoor heat exchanger 20.The 3rd valve port P3 that is connected to compressor 11 inlet sides is communicated with the 4th valve port P4 that is connected to outdoor heat exchanger 30.
Simultaneously, in defrosting mode, the first valve port P1 is communicated with the 4th valve port P4, and the second valve port P2 is communicated with the 3rd valve port P3.Heat is conigenous outdoor heat exchanger 30, thereby the frost on it is removed.
As depicted in figs. 1 and 2, outdoor heat exchanger 30 is equipped with a single coolant channel 31, is formed with refrigerant mouth 32 that is connected to the coolant channel 31 that flows to reversal valve 13 the 4th valve port P4 and the swelling part 40 that is used for the expansion refrigeration agent respectively in the upper and lower of outdoor heat exchanger 30.
So, when from the downward refrigerant of the cryogen flow mouth 32 of last refrigerant mouth 32, the temperature of refrigerant reduces, thereby the frost on the outdoor heat exchanger 30 can not be removed effectively.In addition, spend the oversize time to remove frost on the outdoor heat exchanger 30, thereby the efficient that the interior space is heated up reduces.
Therefore, the purpose of this invention is to provide a kind of heat pump type air conditioner, can be by removing the heat exchanger effectiveness that frost on the outdoor heat exchanger improves outdoor heat exchanger rapidly and effectively.
For realizing above-mentioned purpose of the present invention, provide a kind of heat pump type air conditioner with a plurality of series connection and coolant channel in parallel.
Outdoor heat exchanger is formed with one and is connected to first coolant channel that flows to reversal valve first valve port, and one is series at second coolant channel and three coolant channel in parallel with second coolant channel of first coolant channel.First coolant channel is formed on the bottom of outdoor heat exchanger, and second coolant channel is formed on the top of outdoor heat exchanger, and the 3rd coolant channel is formed between first and second coolant channels.One side of the second and the 3rd coolant channel is connected to the swelling part of an expansion refrigeration agent.
The refrigerant that has been compressed by compressor is removed the frost on the outdoor heat exchanger for the first time when flowing through first coolant channel, defrost once more when flowing through the second and the 3rd coolant channel.
According to characteristic of the present invention, the frost on the outdoor heat exchanger is removed rapidly and effectively, has improved heat exchanger effectiveness, and the interior space can be heated effectively.
Explain preferred embodiment by consulting accompanying drawing, above-mentioned purpose of the present invention and other benefit will become clearer, wherein:
Fig. 1 is the schematic diagram of a conventional heat pump type air-conditioner;
Fig. 2 is the perspective view of an outdoor heat exchanger shown in Fig. 1; And
Fig. 3 is the schematic diagram of the heat pump type air conditioner of one embodiment of the present invention.
Fig. 3 represents the heat pump type air conditioner 100 of one embodiment of the present invention.In Fig. 3, the air-conditioner 100 of the preferred embodiment of the present invention comprises a compressor 112 that is used for compression refrigerant, a flow direction that is used for optionally changing compressed refrigerant flow to reversal valve 114, with the outdoor unit 110 that disposes outdoor heat exchanger 116, this heat exchanger has a plurality of coolant channels 118,120 and 122.
In heating mode, flow to reversal valve 114 the first valve port P1 that is connected to compressor 112 1 outlets is communicated with the second valve port P2 that is connected to indoor heat exchanger 140.In addition, the 3rd valve port P3 that is connected to compressor 112 1 inlet is communicated with the 4th valve port P4 that is connected to outdoor heat exchanger 116.
Simultaneously, in defrosting mode, flow to reversal valve 114 and the first valve port P1 is communicated with the 4th valve port P4 and the second valve port P2 is communicated with the 3rd valve port P3.
The swelling part 130 that is used for the expansion refrigeration agent comprise one connect with the second and the 3rd coolant channel 120 and 122, in order to prevent the check-valves 132 of cryogen flow to outdoor heat exchanger 116; Connect in order to first capillary 134 of expansion refrigeration agent with check-valves 132 for one; With one be in parallel with check-valves 132 and be used for second capillary 136 of expansion refrigeration agent.First capillary 134 is connected in indoor heat exchanger 140.
The operation of the heat pump type air conditioner 100 of the preferred embodiment of the present invention hereinafter will be described.
Under heating mode, the first valve port P1 that flows to reversal valve 114 is communicated with the second valve port P2 being introduced indoor heat exchanger 140 by the refrigerant that compressor 112 compresses.The 3rd valve port P3 is communicated with the 4th valve port P4 on the other hand, thereby the refrigerant of discharging from outdoor heat exchanger 116 is introduced into compressor 112.
Refrigerant and the room air of introducing indoor heat exchanger 140 exchange its inner heat so that interior space intensification is arranged then to first capillary 134.Refrigerant expands by first capillary 134 and second capillary 136, is introduced into outdoor heat exchanger 116 then.
Refrigerant carries out exchange heat the coolant channel 118,120 of the outdoor heat exchanger 116 of flowing through and with outdoor air at 122 o'clock, to be introduced into compressor 112 by flowing to reversal valve 114.
Simultaneously, in the refrigeration pattern, introduced first coolant channel 118 via the first and the 4th valve port P1 that flows to reversal valve 114 and P4 by the refrigerant that compressor 112 compresses.Refrigerant is at first removed the frost on the outdoor heat exchanger 116 when flowing through first coolant channel 118, be introduced into the second and the 3rd coolant channel 120 and 122 then.When flowing through the second and the 3rd coolant channel 120 and 122, refrigerant is removed the frost on the outdoor heat exchanger 116 repeatedly, is introduced into swelling part 130 then.Refrigerant expands to be introduced into indoor heat exchanger 140 when flowing through first capillary 134 via check-valves 132.
According to heat pump type air conditioner of the present invention, the frost on the outdoor heat exchanger is removed rapidly and effectively to shorten defrosting time.By means of this operation, the efficiency of heating surface of indoor heat exchanger is improved.
Though the present invention is had been described in detail with reference to specific embodiment, should be appreciated that under the condition that does not deviate from spirit and scope of the invention, can make change on various forms and the details to the present invention.
