Description

Evaporative condenser heat pump formula full heat recovery fresh air unit

 

Technical field

The present invention relates to a kind of full heat recovery fresh air unit, particularly relate to a kind of evaporative condenser heat pump formula full heat recovery fresh air unit.

 

Background technology

Existing building, in order to meet the requirement of comfortableness (heating or refrigeration), has generally been installed air-conditioning.Air-conditioning is conditioner, refers to the device that the parameters such as the temperature of surrounding air in building/structures, humidity, cleanliness factor, speed is carried out to regulation and control.The structure of air-conditioning comprises the elements such as compressor, condenser, evaporimeter, cross valve, check valve capillary module.Wherein, the specified course of work that between cog volume is right in compressor of air conditioner.Female screw, positive screw rod turn to cater to mutually a side gas by compression, this side is called higher-pressure region; On the contrary, screw rod turns to the side between cog volume deviating from each other expanding and being in expiratory phase, is called low-pressure area.Higher-pressure region, low-pressure area are separated by the contact wire between female screw, positive screw tooth surface.Can think approx: two screw rods axis place plane is the interface in high and low pressure district.Compressor sucks the working substance steam from evaporimeter lower pressure out, make it after pressure raises to send into condenser, in condenser, be condensed into the liquid that pressure is higher, after choke valve throttling, after becoming the liquid that pressure is lower, send into evaporimeter, in evaporimeter, heat absorption is evaporated and is become the steam that pressure is lower, thereby completes kind of refrigeration cycle.Capillary module comprises capillary and check valve, and wherein check valve is widely used in air-conditioner outdoor unit, and it is comprised of assisted capillary and check valve, and the check valve assembly of the machine of air-conditioning different model is similar.On check valve, have an arrow, it represents that air-flow can only be to flow according to the direction of arrow, oppositely stops, and can only pass through from assisted capillary.Check valve assembly is arranged on the lower rear of off-premises station, conventionally has the snubber block of a black color wrapping, and bag pitch has been the effect of noise reduction.

But existing air-conditioning only can regulate temperature, can not exchange of air or purify air, of long duration will cause air pollution, affect health.

The specific embodiment

Below in conjunction with accompanying drawing, provide preferred embodiment of the present invention, to describe technical scheme of the present invention in detail.

As shown in Figure 1, evaporative condenser heat pump formula full heat recovery fresh air unit of the present invention comprises framework 1, wet-membrane humidifier 2,evaporimeter 3, filter 4,new wind entrance 5,condenser 6,compressor 7,return air entrance 8,ajutage 11,exhaust duct 12, dividingplate 15, wet-membrane humidifier 2,evaporimeter 3 is all betweennew wind entrance 5 andajutage 11,condenser 6,compressor 7 is all betweenreturn air entrance 8 andexhaust duct 12,new wind entrance 5,return air entrance 8 is all positioned at a side of framework 1,ajutage 11,exhaust duct 12 is positioned at the opposite side of framework 1, dividingplate 15 is positioned at the centre of framework 1 andnew wind entrance 5 andreturn air entrance 8 is separated.

One side ofajutage 11 is provided with thefirst peep hole 13, and a side ofexhaust duct 12 is provided with thesecond peep hole 14, convenient like this air-supply and the air draft situation of observing.

The side ofreturn air entrance 8 is provided withdistribution box 10, convenient like this power supply.
