The device that is used for indoor fresh air dehumidification, purification and air draft recuperation of heat
The utility model belongs to the hvac equipment technical field, relate to a kind of device that is used for the indoor fresh air dehumidification of building, purification and air draft recuperation of heat, its product is mainly used in the air humidity of indoor temperature and humidity independence control air conditioner system and handles and the recuperation of heat utilization, also can be used for the fresh-air ventilation recuperation of heat in the conventional air-conditioning.
Traditional building indoor purifying and air draft heat reclamation device generally all adopt the runner heat exchange mode, belong to the temperature difference and transmit naturally.The device of this structure is because wind speed is very fast, heat-exchange time is short, so energy recovery efficiency is lower, and because the running of runner can cause new wind to pollute inevitably, has also reduced air quality.In addition, traditional air conditioner condensation unit dehumidifying can cause room temperature to descend when moving, and generally also need open other aircondition and promote room temperature.
The utility model content
The purpose of this utility model is the problem that prior art exists is solved, so provide a kind of rational in infrastructure, design is easy to use, the device that is used for indoor fresh air dehumidification, purification and air draft recuperation of heat of energy saving economy, high efficiency.
Be used to realize that the technical solution of foregoing invention purpose is such: what provided is used for indoor fresh air dehumidification, the device of purification and air draft recuperation of heat has one and have new wind inlet on the wall side, indoor new wind outlet and indoor exhaust wind inlet, the housing of wind exhausting outlet, in housing, be provided with by compressor, four-way change-over valve), condenser, choke valve, the air-conditioning unit that evaporimeter is formed, the gas outlet of compressor joins by a siphunculus mouth of four-way change-over valve and condenser or evaporimeter, another siphunculus mouth of condenser and evaporimeter interconnects by choke valve, the air inlet of compressor is inserted in the gas outlet of four-way change-over valve, vaporizer side at housing is equipped with a cold scattering blower fan, at the condenser side of housing a cooling fan is housed.
The utility model utilizes air draft to carry out the refrigeration and heating change working as the unit Cooling and Heat Source and by cross valve, the operation logic of its air-conditioning unit is consistent with vapor compression refrigeration system, the high temperature and high pressure gas that compressor is discharged enters condenser through four-way change-over valve, carry out exchange heat with air draft, refrigerant temperature reduces after enter evaporimeter after the choke valve step-down, after carrying out exchange heat with new wind, low-temperature low-pressure refrigerant enters compressor and finishes systemic circulation.When the utility model freezes summer from new wind draw heat be dispersed in the air draft, during winter heating from air draft draw heat be discharged in the new wind, the transition season unit is out of service, only carries out replacement aeration and does not carry out exchange heat.Unit is when summer operation, owing to utilize air draft as low-temperature receiver, temperature of outgoing air is lower than outside air temperature, and condensation temperature reduces, and unit operation efficient improves; During winter operation, utilize air draft as thermal source, because winter, temperature of outgoing air was higher than outside air temperature, the unit evaporating temperature improves, and operational efficiency improves.The utility model is owing to utilize air draft as Cooling and Heat Source, obviously improved the air-conditioning system operating condition, improved unit operation efficient, can save the air displacement operating cost greatly, again because when the air-conditioning unit carries out the heat conversion, new wind is separate with exhaust system, avoided the conventional apparatus existence air pollution problems inherent.This device is annual all can to carry out purified treatment to introducing indoor new wind and room air, helps promoting indoor air quality, when dehumidifying operation separately, can not cause indoor temperature to reduce.
Device described in the utility model both can be lifted under the indoor ceiling, also can land installation.

The specific embodiment
Below with reference to drawings and Examples content of the present utility model is described further, but actual fabrication structure of the present utility model is not limited in following embodiment.
Referring to accompanying drawing, the device that is used for indoor fresh air dehumidification, purification and air draft recuperation of heat described in the utility model mainly comprises air-conditioning unit, VMC, exhaust system three parts.
The air-conditioning unit connects to form successively by pipeline and forms by being located at compressor 1, four-way change-over valve 2, condenser 3, throttling arrangement 4, evaporimeters 5 in the housing 20, wherein the gas outlet of compressor 1 joins by the siphunculus mouth of four-way change-over valve 2 with condenser 3 or evaporimeter 5, another siphunculus mouth of condenser 3 and evaporimeter 5 interconnects by choke valve 4, the air inlet of compressor 1 is inserted in the gas outlet of four-way change-over valve 2, utilizes air draft to carry out the refrigeration and heating change working as the unit Cooling and Heat Source and by cross valve during work.VMC comprises the cold scattering blower fan 6 that is located at the device vaporizer side, new wind inlet and indoor return air outlet 10, said new wind inlet is a triplet type mouth with outdoor new wind inlet 15 and indoor return air inlet 10, be provided with air cleaner 13, air purifier 12 and new wind control valve 14 at its outdoor new wind 15 ends that enter the mouth, be provided with return air control valve 11 at its indoor return air 10 ends that enter the mouth.During new wind operating mode, outdoor new wind is by outdoor new wind 15 accesss to plant that enter the mouth, carry out exchange heat and dehumidifying with evaporimeter 5 after air cleaner 13, air purifier 12 carry out the air preliminary treatment, dry new wind utilizes cold scattering blower fan 6 to send into indoor through indoor new wind outlet 9; When requirement is carried out dehumidification treatments to indoor return air, open return air control valve 11, close new wind control valve 14, indoor return air enters fresh air treatment system through indoor return air inlet 10, sends back to indoor after evaporimeter 5 carries out dehumidification treatments.When needs are handled new wind simultaneously and indoor return air are carried out dehumidification treatments, can open return air control valve 11 and new wind control valve 14 simultaneously, but by control and regulation indoor return air of valve opening free adjustment and outdoor fresh air proportion.
Exhaust system comprises cooling fan 7, wind exhausting outlet and the indoor exhaust wind inlet 8 that is located at the device condenser side, said wind exhausting outlet is a triplet type mouth with outdoor wind exhausting outlet 16 and indoor air-supply outlet 19, be provided with air draft control valve 17 at its outdoor wind exhausting outlet 16 ends, export 19 ends in its indoor air-supply and be provided with air-supply control valve 18.During the ventilation operating mode, air draft is carried out utilizing cooling fan 7 to drain into outdoor through outdoor wind exhausting outlet 16 after the exchange heat with condenser 3 through indoor exhaust wind 8 accesss to plant that enter the mouth.Close air draft control valve 17 when requiring indoor dehumidification winter, opens air-supply control valve 18, room air through dehumidification treatments after indoor air-supply outlet 19 is sent back to indoor.
When device described in the utility model dehumidifies operation separately, can switch wind exhausting outlet, again send back to air draft indoor, the heat that air draft is drawn is still got back to indoor, so can not cause indoor temperature to reduce, room temperature reduces the sense of discomfort that causes to the people when having avoided traditional dehumidifier dehumidifying to move, also noting be used in dehumidifying operation and starting other aircondition simultaneously and heat keeping room temperature, thereby having saved aircondition because the operating cost that additionally heats demand and produced that the dehumidifying operation causes.
