Description of drawings
Accompanying drawing is a complete machine structure schematic diagram of the present invention.
The specific embodiment
As shown in drawings, the present invention has a cabinet 20, one end of cabinet 20 is provided with a fresh inlet 13, and the length direction from fresh inlet 13 positions along cabinet 20 in cabinet 20 is provided with air cleaner 14, indirect evaporation cooler 15, evaporimeter 5, wet curtain 4, water fender 3 and air outlet 2 successively.Wherein, air cleaner 14, indirect evaporation cooler 15, evaporimeter 5, wet curtain 4, water fender 3 are all settled with cabinet 20 bottom vertical.Also being provided with on the cabinet 20 can be by the air inlet 12 of room air.Evaporative condenser 10 is arranged between indirect evaporation cooler 15 and the air cooled condenser 9, and indirect evaporation cooler 15 tops are provided with shower 18, and shower 18 employed spray waters are catchmented and provided by water pump 16 by indirect evaporation cooler 15 bottoms.Be provided with shower 18 too on evaporative condenser 10 tops, its water source provides by drip tray 19 and the water pump 11 that is positioned at evaporative condenser 10 bottoms.One side of air cooled condenser 9 is provided with water fender 8 and overfire air fan 7.
Compressor 17 both can be located in the cabinet 20, also can be located at outside the cabinet 20, and the cold-producing medium of compressor 17 outputs is delivered to air cooled condenser 9 and the evaporative condenser 10 that is connected in series.Evaporimeter 5 bottoms are communicated with the work loop that forms a compressor 17 again with compressor 17.Between evaporimeter 5 and evaporative condenser 10, also be provided with a choke valve 6.
The cold air of being sent by wet curtain 4 relies on pressure fan 1 to be expelled to indoor from air outlet 2.
The course of work of the present invention:
1, wind course of work
Outdoor new air enters hybrid in the cabinet 20 via fresh inlet 13, indoor return air enters mixing chamber via air inlet 12, filter by air cleaner 14 after outdoor air and indoor the mixing and enter indirect evaporation cooler 15 again, it is preliminary etc. but clammy that wind is obtained.Through a wind of preliminary cooling and then enter evaporimeter 5, to wind dry cooling or etc. clammyly enter wet curtain 4 after but, wet 4 pairs of wind of curtain carry out the air that the constant enthalpy cooling adds after the wet process and are sent to indoor by pressure fan 1 pressurization back by air outlet 2 via water fender 3 backs.
2, the secondary wind course of work
Secondary wind enters unit via indirect evaporation cooler 15 bottoms.At first secondary wind and indirect evaporation cooler 15 outer surfaces carry out heat exchange by the water of shower 18 ejections, and the result of heat exchange is lowered the temperature of secondary wind, and the temperature of cooling water also is lowered simultaneously, and the limit of reduction is the wet-bulb temperature of secondary wind.Then, the secondary wind of lower temperature enters the evaporative condenser 10 of mechanical refrigeration system and evaporative condenser 10 is carried out the convection current cooling, takes away the steam that evaporative condenser 10 outer surfaces produce simultaneously.Then, secondary is distinguished and admirable to go out evaporative condenser 10, enters the air cooled condenser 9 of mechanical refrigeration system, carries out after the heat exchange temperature of secondary wind being raise with air cooled condenser 9 outer surfaces, and last, the higher secondary wind of temperature drains into outdoor via blower fan 7.
3, the mechanical refrigeration system course of work
Compressor 17 sucks low-temp low-pressure freon steam, after pressurization, freon steam becomes the gas of HTHP, the gas of this HTHP is drained into air cooled condenser 9, the Freon gas of HTHP is tentatively cooled off in air cooled condenser 9, and the Freon gas that is tentatively cooled off enters evaporative condenser 10 again.After heat exchange, Freon gas is cooled into the liquid of HTHP, be delivered to evaporimeter 5 by pipeline after being become the liquid of low-temp low-pressure by throttling via choke valve 6 again, the freon liquid of low-temp low-pressure carries out heat exchange in evaporimeter 5, the Freon gas of heat absorption back evaporation becoming low-temp low-pressure, the Freon gas of low-temp low-pressure is sucked by compressor 17 again.The periodic duty that so goes round and begins again.
4, the evaporative condenser water system course of work
Evaporative condenser 10 is divided into drip tray 19, and shower 18 is established on evaporative condenser 10 tops, and water circulating pump 11 is connected between drip tray 19 and the shower 18.
Recirculated water pressurizes after shower 18 sprays to evaporative condenser 10 outer surfaces through water pump 11, because of evaporative condenser 10 hull-skin temperatures very high, water is vaporized very soon and becomes steam, does not have the water of vaporization to fall into the circulation that bottom drip tray 19 is gone round and begun again by water pump 11 suctions again.Simultaneously, the secondary air temperature degree that is flowed out by indirect evaporation cooler 15 is lower, enter evaporative condenser 10 after, the first, can make a part of steam of generation be cooled to liquid, drop onto hot surface and continue evaporative condenser 10 coolings; The second, air that temperature is lower and evaporative condenser 10 outer surfaces carry out heat convection; The 3rd, can take away the steam that evaporative condenser 10 surfaces are produced, reduce the partial pressure of water vapor of evaporative condenser 10 outer surfaces, quicken the vaporization of water, improve heat exchange efficiency; The 4th, secondary wind and recirculated water that temperature is lower carry out heat exchange, make the water that participates in circulation obtain cooling.
5, the indirect evaporative cooler recirculated water course of work
Indirect evaporation cooler 15 circulations are to be made of shower 18, water pump 16.Water pond is established in indirect evaporation cooler 15 bottoms, establishes secondary wind air inlet between water pond and the indirect evaporation cooler 15.
Recirculated water is after water pump 16 pressurizations promote, evenly be showered into indirect evaporation cooler 15 outer surfaces through spray comb 18, under the acting in conjunction of indirect evaporation cooler 15 surfaces and secondary wind, make a part of water vapor, do not have the water droplet of vaporization to fall into the bottom water pond, sucked the back periodic duty by water pump 16.Carry out heat exchange between recirculated water and the secondary wind, water temperature is reduced, the limiting temperature of water temperature can be reduced to secondary rheumatism bulb temperature, and the water of low temperature cools off wind one time in the mode of conduction, convection current, finishes the work requirements of indirect evaporation cooler 15.
The effect of said two water fenders 3,8 is to stop respectively that carrying out after the heat exchange in the air entrained moisture by wet curtain 4, air cooled condenser 9 can not discharge outside the cabinet 20.
The just an example of the present invention that drawings and Examples are represented, other structure of making according to inventive concept all should belong to protection scope of the present invention.
Energy-efficient air conditioner group of the present invention institute produce an effect is:
1, with evaporative cooling, water-cooled, air-cooled combining, constitute jointly the condenser system of multi-functional many effects, collect the advantage of the various types of cooling, learn from other's strong points to offset one's weaknesses, bring out the best in each other, the refrigerating efficiency height need not to increase cooling water system.
2, the Secondary Air of indirect evaporation cooling can provide temperature lower air, and the condensation efficiency of evaporative condenser and air cooled condenser is improved greatly.
3, indirect evaporation cooler carries out pre-cooledly to air, has reduced mechanically refrigerated pressure, is more conducive to energy-conservation.
4, winter, indirect evaporation cooler also can use as the heat regenerator of indoor exhaust wind.
When 5, mechanical refrigeration Winter heat supply operating mode is moved, can prevent the cold junction frosting, improve heat utilization efficiency.
6, do not have refrigerating medium in the system, avoided the refrigerating loss of refrigerating medium, overall efficiency improves.
