Description

A kind of air conditioner indoor unit having for fresh air and wind screen inducing function
Technical field
The present invention relates to air-conditioning system end equipment, more particularly to the changes in temperature with energy conservation and environmental protection and comfort The indoor end device of type air-conditioning.
Background technology
Northern China and part southern area are in winter generally using coal-fired or fuel oil heating system, fossil fuel combustion at present Burning, especially not concentrated combustion are also easy to produce substantial amounts of pollutant emission, and it is relatively low with heat supply efficiency to burn, the wasting of resources and environment It is seriously polluted.
To solve the above problems, the Chinese government is wideling popularize the heating system of this clean and effective of heat pump heating.But It is that, since northern China winter environment temperature is relatively low, the hot water temperature that common single stage compress heat pump system generates is not high enough, and The efficiency of Two-stage Compression system generates great demand again than relatively low to the air conditioner indoor unit of small different transfer of heat.
Fan coil is generally used in current heat pump heating scheme as air conditioning terminal, fan coil installation of ceiling and on Air-supply, in order to meet heat exchange amount requirement, design air flow is larger, wind speed is higher, is presented in room during upper plenum heating and goes up the low temperature of relative superiority or inferiority Gradient is spent, comfort requirement of the human body to " cold foot heat " can not be met with summer in winter simultaneously.
In recent years, heat pump radiant type heating technology is suggested and applies, including floor, ceiling, metope or vertical radiation Heat transfer etc., radiant heat transfer scheme have preferable comfort when heating in winter, shortcoming cannot be taken into account simultaneously for warm cooling Otherness and comfort, and need to set larger radiation heat transfer area.
The content of the invention
The present invention be to avoid the shortcoming present in the above-mentioned prior art, provide it is a kind of have lured for fresh air and wind screen It leads the air conditioner indoor unit of function, the shortcomings that upper air-supply single to avoid air conditioner indoor unit, meets " cold foot heat " and super-silent etc. Comfort requirement;The present invention also provides the mating room for meeting small temperature difference heat supply for low temperature season air source heat pump system efficient operation Interior air conditioning terminal also provides variation using end for comfort air conditioning system.
The present invention adopts the following technical scheme that solve technical problem:
