Description
Technical field
The present invention relates to air-conditioning technique field, more particularly to a kind of total-heat exchanger, control method and air-conditioning.
Background technology
Energy-saving and emission-reduction are the life style that present society is advocated, and major electronics firms also focus on to reduce product in product design
The energy consumption of product.
Reference picture 1, total-heat exchanger includes being provided with Total heat exchange core body 02 in housing 01, housing 01, is opened up on housing 01
There are indoor wind inlet 011 and the fresh air outlet 014 in communication chamber, and connection outdoor indoor air outlet 012 and fresh air inlet
013, after inletting fresh air pattern is started, orthogonal thereto fork mode flows through Total heat exchange core body (in such as Fig. 1 respectively for fresh air and indoor exhaust wind
Direction shown in arrow), because the sidewind of splitter plate two has the temperature difference and vapor partial pressure is poor, two strands of air-flows pass through demarcation strip
Shi Chengxian heat and mass phenomenons, cause Total heat exchange process, and fresh air can obtain cold or heat from indoor exhaust wind, so as to reclaim
Energy, reaches the purpose of energy-conservation.
When outdoor air poor (such as severe haze weather), inletting fresh air is carried out according to total-heat exchanger, easily by room
The air of outer pollution brings interior into, so as to reduce the air quality of interior；Or when room air and outdoor air the temperature difference compared with
When big, inletting fresh air is carried out using total-heat exchanger, after outdoor air carries out heat exchange through total-heat exchanger, room air with it is outdoor
The temperature difference of air is still larger, therefore, the air themperature of interior can be reduced, reduce indoor comfortableness.
