Description
Technical field
The present invention relates to air-conditioning technical field, more particularly to a kind of refrigerating and heating type air conditioner and its indoor set.
Background technology
The refrigerating and heating type air conditioner of current market, in order to adapt to that in the colder region of weather enough heat can be exported
Amount, typically all can increase electric heater by pusher side, when environment temperature is relatively low, heating capacity can not be met by depending merely on air-conditioning system indoors
When, open electrical heating, quantity of heat given up.
As Figure 1-Figure 4, according to present conventional refrigerating and heating type air conditioner, electric heater 2 is all located in indoor set
The inner side of indoor heat exchanger 1, when air conditioner heat-production pattern and relatively low environment temperature, electric heater 2 is opened.Low temperature environment
Air first passes through electric heater 2 under the drive of indoor apparatus of air conditioner wind wheel and exchanged heat, and is then exchanged heat again by indoor heat exchanger 1.One
As for, indoor heat exchanger 1 include windward side and leeward side, wherein for air intake side be windward side, one for air-out
Side is leeward side.
Such a heat exchange mode has unfavorable factor for refrigeration system.Cryogenic air first passes through electric heater and added
Heat, air self-temperature has been improved, and is then exchanged heat, can be known according to the heat transfer temperature difference of thermal conduction study with indoor heat exchanger again
Road, now heat exchange efficiency is decreased, and air-conditioning system high-pressure side can cause system power and electric current because heat exchange amount is reduced
Increase.On the other hand, because electric heater is in the inside of heat exchanger, when air passes through heat exchanger, electric heater can have to air
Stop so that heat exchanger can not fully be contacted with air and exchanged heat, and now also reduce heat transfer effect.
On the other hand, because electric heater is placed on the inner side of indoor heat exchanger, because the space inside indoor heat exchanger
It is limited, so the selection of electric heater volume size can be also restricted.When environment temperature is relatively low, the heating capacity of air conditioner is more
When not enough, it is impossible to increase heating capacity from larger electric heater.
In summary, how to solve in the auxiliary thermal process of refrigerating and heating type air-conditioning, cause the problem of heat exchanger heat exchange efficiency is low, into
For those skilled in the art's technical barrier urgently to be resolved hurrily.
The content of the invention
It is an object of the invention to provide a kind of refrigerating and heating type air conditioner and its indoor set, to improve the heat exchange efficiency of heat exchanger
Problem.
To achieve these goals, the invention provides a kind of indoor set of refrigerating and heating type air conditioner, including indoor heat exchanger
And electric heater, the electric heater is arranged on the leeward side of the indoor heat exchanger.
Preferably, leeward side of the electric heater along the indoor heat exchanger be circumferentially.
Preferably, the electric heater is arranged with the leeward side of the indoor heat exchanger in the way of fitting.
Preferably, there is gap between the leeward side of the electric heater and the indoor heat exchanger.
Preferably, the electric heater heats for resistance-type.
Preferably, the resistance-type is heated to be Resistant heating.
Content, the indoor set of above-mentioned refrigerating and heating type air conditioner, by the way that electric heater is arranged in are introduced compared to background technology
The leeward side of indoor heat exchanger so that in the case where opening heating mode, can allow indoor low temperature air first to be exchanged heat with indoor heat exchanger,
And allow moving air with the abundant contact heat-exchanging of indoor heat exchanger, air passes through electric heater after heat exchanger and changed
Heat, because cold ambient air temperature is directly contacted with indoor heat exchanger, heat transfer temperature difference is larger, greatly improves the heat exchange effect of heat exchanger
Rate.Further, since electric heater is disposed in the interior the leeward side of heat exchanger, therefore electric heater can have larger heat-transfer surface
Product, can make up the heating capacity of air conditioner at low ambient temperatures, improve the comfortableness of air conditioner.
In addition present invention also offers a kind of refrigerating and heating type air conditioner, including indoor set, the indoor set for as described above either one
Indoor set described by case.Because the indoor set has above-mentioned technique effect, the refrigerating and heating type air conditioner with above-mentioned indoor set
There should be corresponding technique effect, will not be repeated here.
Preferably, the refrigerating and heating type air conditioner is ceiling type air conditioner machine.
