Description

A kind of method to indoor air purification refrigeration and dual unit cooling air-conditioner

Technical field

The present invention relates to a kind of indoor air handler, particularly there is the conditioner with water evaporation for cooling, indoor and outdoor ventilation energy and purifying fresh air several functions and recovery is taken a breath.

Background technology

Along with the raising of people's living standard, people to the refrigeration of the air in room, indoor and outdoor ventilation and reclaim ventilation energy and the demand that purifies the air of a room more and more urgent, but the air processor market simultaneously possessing these functions is also had no precedent, people have to meet these demands with multiple devices such as compressed air conditioner device, fresh air ventilator air purifiers, not only invest high, floor space is large, and has some to be difficult to the shortcoming overcome.

The power consumption of compressed air conditioner device is high, complex structure, manufacturing cost are high, cold-producing medium is the chlorine Lyons destroying atmospheric ozone layer, its development does not meet the world trends of environmental protection and energy saving, there is no the current of effective substitute, its a large amount of uses are a kind of unavoidable makeshift.In recent years many people attempt to solve this problem with water evaporative cooling, the evaporation type air conditioner domestic type of the direct evaporative cooling of water is utilized to be commonly called as " air cooler ", commercial style is commonly called as " environment-friendly air conditioner ", but its principle is air equal-enthalpy humidifying, can only lower the temperature and can not freeze, China most area higher to humidity all can not replace compressed air conditioner.Number of patent application is 201210168743.0, it is by name that " dew point is indirect, direct evaporative cooler modularization Evaporative Cooling Air Conditioning " creativity and innovation disclose the technical scheme that a kind of direct evaporating-cooling and indirect evaporating-cooling combine, but its indirect evaporating-cooling is wall-type heat exchange, efficiency is very low, the equal-enthalpy humidifying being still direct evaporating-cooling played a major role, its effect is not improved than evaporation type air conditioner at all, outdoor air after treatment full heat drop is seldom low, can only close to its wet-bulb temperature, can not close to dew point, structure is more complicated on the contrary, water consumption is more.Even if can close to dew point, much regional in China, high temperature season dew point, more than 23 DEG C, can not replace air-conditioning.

For overcoming the shortcoming of existing compressed air conditioner, industry has carried out a large amount of trials, mainly in absorption type air-conditioner and dehumidification air conditioner etc.Absorption type air-conditioner is except equipment investment is than except compression height, and also there is the corrosivity of hygroscopic agent, system sealing and need thermal source, the not energy-conservation difficult problem of economize on electricity, industry thinks that this is this Air-conditioning Development insurmountable barrier.There is heat source in dehumidification air conditioner, though the limitation that sharp solar energy and other low-grade heat source can save energy equipment investment and domestic consumer constrains applying of it, their overall economics far away can not be comparable with compressed air conditioner equally.

From refrigeration principle, above various technical scheme does not all break through single evaporation refrigeration or the limitation of dehumidifying, thus their technical-economic index also difficulty have breakthrough improvement.

At home and abroad market dominates fresh air ventilator is cross-flow plate type heat exchanger, the short economic worth almost making it lose actual use in low, service life of its heat recovery rate.

Today that indoor air cleaner becomes in air pollution the focus that people pay close attention to becomes the required household effects of average family very soon, but it can only eliminate the solid particle in room air, can also decomposing or formaldehyde adsorption of minority, the pernicious gases such as benzene, but because its process air quantity is very limited, must close the door during use, indoor carbon dioxide, the savings of carbon monoxide, the health of shortage to people of fresh oxygen brings new harm, with health care maximum magic weapon---ventilation runs in the opposite direction, saying nothing of the configuration of its family expenses is exactly unit even up to ten thousand of thousands of unit easily, ordinary consumer is allowed to hope and to halt.

In addition this three kind equipment is that Each performs its own functions, and a general human residential space needs three complete, both uneconomical, aobvious numerous and diverse again, even becomes the burden of family.

Consumer look forward to have a kind of there is compressor-free simultaneously, the refrigeration of non-freon, indoor and outdoor ventilation and the conditioner reclaiming the ventilation several functions such as energy and purifying fresh air be born, but have not yet to see such technical scheme so far.

Summary of the invention

The object of the invention is to overcome prior art function singleness, the needs of each side of air-treatment can not be met simultaneously, and existing air-conditioner power consumption is high, complex structure, manufacturing cost are high, contaminated environment, existing ventilator heat recovery rate is low, service life is short, existing air purifier can not the shortcoming of ventilation, there is provided a kind of and possess the function of above three kind equipments and the air-treatment technology of high efficiency, low cost and equipment simultaneously, particularly provide a kind of area at all high dew points of China can replace the environmental protection and energy saving refrigeration plant of compressed air conditioner.

The working condition of dehumidification system is identical with embodiment 1.

Above each embodiment all can be used for damp and hot load higher district use air-conditioner, the present invention is when the xeothermic area lower for dew point in summer, can omit dehumidification system in enforcement, this is that any technical staff does not add any performing creative labour according to the present invention and all can realize.Below two specific embodiments.

Embodiment 5:

This example is used for the lower xeothermic area of dew point, substantially identical with embodiment 1,2 agent structure, also be a kind of rotary-type air-conditioner, difference is only: this example does not need the second level to freeze, and fully phases out whole fresh air dehumidifying system 60, because new wind can wait and wetly cool to close to dew point in filtration heat exchanger, if dew point 22 DEG C, new wind etc. are wet when cooling to 26 DEG C, and relative humidity is 78%, so all dew points are not higher than the place of 22 DEG C, the requirement of comfort air conditioning system can be met by this example.

Figure 14 is the enthalpy-wet figure of the wet cooling refrigeration process such as grade of a worst hot case, before the initial state of this operating mode and air-conditioning work, indoor-outdoor air state point a1 is: dry-bulb temperature 45.0 DEG C, relative humidity 20%, enthalpy is 76.4 kJ/kg, water capacity 12.0 g/kg, dew point about 18 DEG C.Refrigeration work process is as follows:

1), start after, state be a1 room air to be discharged filtration heat exchanger in equal-enthalpy humidifying to wet-bulb temperature, state becomes b1 point, its dry-bulb temperature, relative humidity, enthalpy, water capacity distinguish 25.7 DEG C, 95%, 76.4 kJ/kg, 19.8 g/kg.The temperature of the filtration heat exchanger of directly contact is with it also close to 25.7 DEG C simultaneously;

2), state is that the outdoor air of a1 enters filtration heat exchanger, be in direct contact with it the wet refrigeration such as heat exchange, temperature drops to close to 25.7 DEG C, becomes state a2 after entering the thermic load in indoor absorption chamber, and temperature about 31 DEG C, enthalpy are that 62.0 kJ/kg, water capacity do not become 12.0 g/kg;

3), the room air of state a2 is more after filtration outside heat exchanger discharge chamber, and in filtration heat exchanger, equal-enthalpy humidifying is to wet-bulb temperature, and state becomes b2 point, and exhaust drops to about 21.9 DEG C with the temperature of filtration heat exchanger;

4), state is that the outdoor air of a1 enters filtration heat exchanger, be in direct contact with it the wet refrigeration such as heat exchange, temperature drops to close to 21.9 DEG C, becomes state a3 after entering the thermic load in indoor absorption chamber, and temperature about 25 DEG C, enthalpy are that 55.8 kJ/kg, water capacity do not become 12.0 g/kg;

5), so constantly circulation, the room air wet cooling such as constantly, state point constantly along etc. wet line move down into a4, a5 ... point, until reach its limiting condition---dew point.

Above ai point is the state variation track of room air when air-conditioning work, ai by a1 along etc. wet line move down, to the last approach dew point.

But because outdoor heat constantly can import indoor into from wall, the refrigerating capacity of each circulation is also limited, and in fact ai differs and reaches dew point surely, but when the refrigerating capacity of real system is equal with indoor-outdoor air enthalpy difference, temperature no longer reduces, and process of refrigerastion reaches equalization point.

Because relative humidity does not feel like oneself starting more than 70% people, so state a4 can be taken as desirable operating point, now air dry-bulb temperature 22.0 DEG C, relative humidity 72%, enthalpy are that 52.7 kJ/kg, water capacity do not become 12.0 g/kg;

Usually get on very well, all dew points are lower than 22 DEG C or the water capacity climatic condition lower than 17.0 g/kg, use the machine all can obtain the air-conditioning effect of temperature 26 DEG C, relative humidity about 70%, can replace compressed air conditioner, in China, most of regional highest temperature all can meet this condition season.

Embodiment 6:

This example is used for the lower xeothermic area of dew point, agent structure is substantially the same manner as Example 4, also be a kind of rotary valve air-conditioner, difference is only: this example does not need the second level to freeze, fully phase out whole fresh air dehumidifying system 60, the remainder of embodiment 4 need not change completely, and wet process of refrigerastion enthalpy such as its grade-wet figure also as shown in figure 14.This example is used for summer dew point lowlyer can replace compressed air conditioner completely as the area higher than 22-23 DEG C.

Each example all can do window or wall-hanging, tableland formula installation above, if furred ceiling has sufficient space, being installed in furred ceiling is also a well selection.If connect bellows at fresh wind port and exhaust outlet to do portable installation, be more suitable for the custom of the states such as America and Europe.

These are only and implement several concrete structure of the present invention, industry technical staff need not carry out according to the method to indoor air purification refrigeration provided by the invention the dual unit cooling air-conditioner that any performing creative labour also can design much different concrete structures.
