Description
One, technical field: a kind of waste heat recovery compensation type fresh air conditioner configuring method and device belong to the aircondition of electronic product, utilize this configuring technical and device, can effectively reclaim with conversion using waste gas (or not net air) in heat (low temperature or high temperature) obtain high efficiente callback and conversion utilizes again, the place and the environment that can be widely used in various industrial processes workshop, chemical industry workshop, rubber plastic processing, pharmacy and other special air quality requirements are realized brand-new wind constant temperature regulation and control.Said new wind is complete ozone.
Two, background technology: present known industrial production environment of people or manufacturing shop, general all is more airtight local space, a lot of industry is made to have a large amount of pernicious gases and emission of bad smell and causes the air severe contamination in the job shop, cause the deterioration of artificial environment condition.Traditional aircondition all is the mode that has adopted filter type and additional sterilizing and purifying mostly, is difficult to realize directly adopt brand-new wind to carry out the Thermostatic air exchanger air-conditioning, is difficult to reach the ideal effect of taking into account brand-new wind ventilation and energy efficient simultaneously.
When utilizing traditional mode to be used for the whole fresh wind air-condition in industrial premises or workshop (dusty gas is particularly arranged or have in the environment of certain noxious gas emission), in order to make the air quality in the working environment reach certain effect, usually need utilize contaminated air in a large amount of disposable air-conditioning (cold wind or hot blast) displacement working environment (workshop), because disposable new air heat-exchange is to the huge consumption of air conditioner energy, the refrigeration of air-conditioning equipment (heating) amount generally needs to increase several times of needs that can satisfy dynamic constant temperature regulation and control; The increase of air conditioner energy has simultaneously also caused the sharp increase of equipment investment; In addition, air-conditioning wind is the purpose that reaches regulating and controlling temperature and humidity in the local space circulation, traditional method just strengthens the supporting refrigeration of air-conditioning equipment or heats energy (increasing energy consumption power), to replenish because of the huge needed energy consumption of brand-new wind power consumption (generally being the doubly above supporting symbol lotus of 1-2 of common building thing room air conditioner at least), promptly cause a large amount of energy wastes, increased the investment of corollary equipment again; Traditional air-conditioning equipment and configuration-system are difficult to realize industrial waste gas or not effective recovery and reuse of clean environment thermal energy, are difficult to realize the economical operation and the configuration of brand-new pneumatic attitude constant temperature air conditioning.
Three, summary of the invention:, the purpose of this invention is to provide a kind of waste heat recovery compensation type fresh air conditioner configuring method and device according to the problem of above-mentioned existence.The technical program, adopt the mode of differential temperature heat exchange and waste heat feedback (positive feedback) compensation, can be with contained heat energy (high temperature or low temperature) high efficiente callback and conversion using in the large quantity of exhaust gas of different air conditioner surroundings (or workshop) discharging, thereby reach the operating condition condition, raising conversion efficiency, the reduction operation energy consumption that improve heat pump air conditioner, realize the purpose of whole fresh wind air-condition; Make the brand-new wind regulation and control of industrial aircondition realization in the process of refrigeration cool-down and winter heating heating in summer and reach high energy-conservation.
The method that present technique is taked is: design in air-conditioning system and increased the step differential temp type thermal energy exchange and reclaim and the waste heat feedback compensator, make a large amount of heat energy (low temperature or high temperature) of being discharged when changing wind in the air conditioner surroundings (workshop) obtain reclaiming conversion utilization again, thereby compensate a large amount of power consumptions of the air-conditioning unit that causes because of a large amount of disposable new wind displacements; Reclaim heat energy (low temperature or high temperature) by the step differential temp type exchange and carry out first preheating (or precooling) importing new wind, utilize positive (temperature required identical) feedback compensation again, the surface temperature (cross low temperature or cross high temperature) of outdoor heat exchanger is improved (improve or reduce), thereby improved the surface heat exchanging temperature difference of heat exchanger, heated (or refrigeration) effect thereby improved.
Device of the present invention is mainly by compressor, four-port conversion value group and first heat exchanger, double-effective dual temp conversion equipment part mechanism, and constitutes package unit with second heat exchanger, return-air surge tank, heat regenerator and suction blower fan and workshop pipeline loop.
The invention has the beneficial effects as follows can be on the basis of conventional air-conditioning device or two warm pump air-conditioning unit function systems, increase heat-energy recovering apparatus at the exhaust outlet place, just can make the heat energy that is discharged under the situation that no medium mixes, obtain high efficiente callback and conversion utilization again, make to reach in the various industrial environments and realize brand-new wind, can realize high energy-conservation industrial air-conditioning purpose again.Can be widely used in various industrial manufacturing, petrochemical industry, plastic cement processing, pharmaceutical production, cotton spinning etc. have varying environment and purify factory building workshop and the environment that requires; The synthesis energy saving that is particularly useful for common air conditioning system.
Four, description of drawings: as figure is structural principle schematic diagram of the present invention.
Among the figure 1, the import department of the exit 12 of the outlet 11 of the new wind air inlet 10 of compressor 2, four-port conversion value group 3, first heat exchanger 4, double-effective dual temp conversion equipment 5, second heat exchanger 6, return-air surge tank 7, heat regenerator 8, workshop pipeline loop 9, heat regenerator, heat regenerator, first heat exchanger, suction blower fan 13, first heat exchanger
