Description

It is a kind of to strengthen radiation and heat convection and the indoor apparatus of air conditioner of comfortableness
Technical field
The present invention relates to air-conditioning system end equipment, more particularly to the changes in temperature with energy-conserving and environment-protective and comfortableness The indoor end device of type air-conditioning.
Background technology
Northern China and part southern area are in the winter time 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, because northern China winter environment temperature is relatively low, hot water temperature caused by common single stage compress heat pump is not high enough, and The efficiency of Two-stage Compression system generates great demand again than relatively low to the indoor apparatus of air conditioner 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, presented in order to meet that heat exchange amount requires that design air flow is larger, wind speed is higher, during upper plenum heating in room and go up the low temperature of relative superiority or inferiority Gradient is spent, comfortableness requirement of the human body to " a cold pin heat " can not be met with summer in the winter time simultaneously.
In recent years, heat pump radiant type heating technology is suggested and applied, including floor, ceiling, metope or vertical radiation Heat transfer etc., radiant heat transfer scheme have preferable comfortableness when heating in the winter time, shortcoming can not take into account heating and cooling simultaneously Otherness and comfortableness, and need to set larger radiation heat transfer area.
The content of the invention
The present invention is to avoid the weak point present in above-mentioned prior art, there is provided one kind strengthens radiation and heat convection With the indoor apparatus of air conditioner of comfortableness, the shortcomings that to avoid indoor apparatus of air conditioner single upper air-supply, meet " a cold pin heat " and super-silent Equivalent comfort requirement;The present invention also provides for low temperature season air source heat pump system efficient operation meets the supporting of small temperature difference heat supply Room conditioning end, also provide variation for comfort air conditioning system and apply end.
The present invention adopts the following technical scheme that to solve technical problem:
It is cold-warm type air-conditioning room that the present invention, which strengthens radiation and heat convection and the indoor apparatus of air conditioner of comfortableness, the indoor set, Interior machine, it is structurally characterized in that:The body of the indoor set is cuboid, uptake is set on the top plate of body, in body The bottom of preceding facade sets lower air port, in the horizontally disposed wind screen air-out in long and narrow in the top of the preceding facade of body Mouthful, the inclined inside for being placed in body of heat exchanger;In the body, the lower section of uptake is in, and is located at the top of heat exchanger Portion sets two-way ventilating cross flow fan;Preceding facade in the body, it is between the lower air port and wind screen air outlet and sets Exchange heat panel, and the wind screen air outlet passes through the wind screen air supply duct being arranged in body and the air pump positioned at the bottom of body It is connected, the porch of the air pump is empty by the part before lower air port air-out using the air pump at the back in lower air port Gas is through the air-out in wind screen air outlet of wind screen air supply duct;The working condition of the indoor apparatus of air conditioner is set including being:
