2) density is sunken to bottom more greatly, dirty gas sucks through dirty gas air inlet (9), flow through total-heat exchanger (21) heat exchange, heat is absorbed by the new wind of outdoor low temperature sucked through fresh wind inlet (10), after dirty gas cooling under the effect of external dirty gas exhaust blower outside dirty gas exhaust outlet (23) discharge chamber, new wind after heat exchange is delivered to evaporimeter centrifugal blower (11) through ventilation centrifugal blower (20) and is entered indoor, reduce new wind and the room air temperature difference, these have just entered indoor new wind and have been sucked through indoor circulation return air inlet (5) by evaporimeter centrifugal blower (11) again very soon, and flow through fluorine system evaporator (22), again indoor overhead is sent into by evaporimeter centrifugal blower (11) after again being heated by this evaporimeter (22), form circulating-heating, by regulation and control system in use procedure, preset temperature is interval, make compressor when indoor temperature reaches predetermined value, automatic startup or closedown, guarantee that indoor temperature remains on predetermined interval, simultaneously by control system, setting timing ventilation, reduce room air and cause thermal loss because starting air exchange system continuously, reduce energy consumption.Meanwhile, condenser exhaust outlet (25) can be connected to neighbouring refrigerating chamber through air channel, chilled goods is lowered the temperature.
Embodiment three, dries: heighten determining hot temperature degree, connects the auxiliary temperature at air outlet (4) place that makes of electricity and reaches 60 DEG C ~ 85 DEG C, reach drying effect.
Embodiment four, new wind ventilates, ventilation, Total heat exchange reclaims: when needs ventilation, the MOD of circuit ON fresh wind air inlet (10) and dirty gas exhaust outlet (23), start ventilation centrifugal blower (20), evaporimeter centrifugal blower (11) and the external dirty gas exhaust blower of dirty gas exhaust outlet (23), outdoor fresh air and foul indoor gas are aspirated through total-heat exchanger (21) heat exchange, reduce the indoor-outdoor air temperature difference, dirty gas is outside dirty gas exhaust outlet (23) discharge chamber, new wind after heat exchange is delivered to evaporimeter centrifugal blower (11) through ventilation centrifugal blower (20) and is entered indoor, realize cold and hot conversion, reclaim energy-conservation.
Embodiment five, ground source heat and the heat utilization of useless source: when environment does not need to start compressor, underground water or steam, hot water etc. can be utilized long-term constant temperature, by water through frequency conversion water system access water system evaporimeter (22 '), and start evaporimeter centrifugal blower (11) and heat pump, allow water circulate in evaporimeter, blower fan by indoor recycle heat, reach cooling, heat up and energy-conservation.
Embodiment six, heat pump utilizes heat against card principle, heat energy, underground water and used heat in air is absorbed, and realizes heating up or cooling.
