Good application；Cobble bed 12 is closely piled up by several cobbles, and wherein the average diameter of cobble is 1cm~10cm, is convenient for
It closely piles up, thus better accumulation of heat.
The course of work of Winter-summer dual purpose recuperation of heat indirect evaporating-cooling air-conditioning system of the present invention with cobble bed accumulation of heat is specific
It is as follows:
1. the course of work of whole system is as follows:
(1) in summer operation, opens check valve b11 closes check-valves a10, using above sending formula next time, specific works mistake
Journey are as follows:
Indoor environment return air is sent into buried air ducts 30 through return air outlet 29, then by buried air duct 30 through backwind tube 18, return
Wind entrance 22 is sent into recuperation of heat-evaporation cooling combined air conditioner unit, by filter b14 (bag filter) to Indoor environment
Return air carries out purified treatment, forms clean return air；Clean return air enters the return air channel 27 of 5 lower section of plate-fin heat exchanger
Interior, high-pressure spraying unit a4 can spray water into return air channel 27 and form moisture film in return air channel 27, and clean return air is in return air
With moisture film hot and humid area occurs for flowing from bottom to top in channel 27, makes the lower Indoor environment return air temperature of script temperature into one
Step is lowered, and forms low temperature return air；
Simultaneously with the above process, outdoor fresh air enters in recuperation of heat-evaporation cooling combined air conditioner unit through air inlet 21, by
Filter a1 (bag filter) carries out purified treatment to outdoor fresh air, obtains clean fresh air；Clean fresh air enters plate wing
In fresh air runner in formula heat exchanger 5, and low temperature after cooling is transferred heat to by the heat exchanger plates in plate-fin heat exchanger 5
Clean fresh air is pre-chilled in return air using low temperature return air, form low temperature fresh air；Low temperature fresh air flows into direct evaporative cooler,
Direct evaporating-cooling is carried out at wet direct evaporating-cooling filler 7, further decreases temperature, and formation meets air-supply condition
Cold wind；The cold wind for meeting air-supply condition is sent out under the action of pressure fan 8 through air outlet 26, then is sent into and is built through air supply tube 20
In object room.
(2) when working in winter, opens check valve a10 closes check-valves b11, formula next time, specific works mistake is sent under
Journey are as follows:
The higher return air of Indoor environment temperature is sent into buried air duct 30 through return air outlet 29, then is passed through back by buried air duct 30
Air hose 18, return air inlet 22 are sent into recuperation of heat-evaporation cooling combined air conditioner unit, right by filter b14 (bag filter)
Indoor environment return air carries out purified treatment, forms clean return air；Clean return air enters returning for 5 lower section of plate-fin heat exchanger
In wind channel 27, does not supply water, i.e., do not sprayed water into return air channel 27 to high-pressure spraying unit a4 at this time；
Simultaneously with the above process, outdoor fresh air enters in recuperation of heat-evaporation cooling combined air conditioner unit through air inlet 21, by
Filter a1 (bag filter) carries out purified treatment to outdoor fresh air, obtains clean fresh air；Clean fresh air enters plate wing
In fresh air runner in formula heat exchanger 5, the higher return air of temperature is transferred heat to by the heat exchanger plates in plate-fin heat exchanger 5
Clean fresh air, preheats fresh air in fresh air channel；Fresh air flows into direct evaporative cooler after preheating, by dry
It is sent out under the action of pressure fan 8 through air outlet 26 after direct evaporating-cooling filler 7, then successively through air supply tube 20, connection air hose
19 enter in cobble bed thermal storage unit；Solar energy air heat collector 13, which absorbs solar thermal energy, can be pre-stored in cobble bed 12,
Cobble bed 12 can be used for heating the air after the preheating being sent into through connection air hose 19, further increase the temperature of fresh air,
Form warm wind；Warm wind is sent into Indoor environment through floor air supply register 28.
2. the course of work of water system is specific as follows:
(1) in summer operation:
Periodically clean water is sent into header tank 16, then water is sent into height through water supplying pipe 24 under the action of water pump b17
It presses in spray unit a4, water is sprayed to the return air channel to 5 lower section of plate-fin heat exchanger from top to bottom by high-pressure spraying unit a4
In 27, the return air of Indoor environment carries out hot and humid area in return air channel 27, and extra water flow returns to middle continuation in header tank 16
Circulation；
In direct evaporative cooler, high-pressure spraying unit b6 fills out the water spray in water storage box 23 in direct evaporating-cooling
On material 7, direct evaporating-cooling filler 7 is soaked, the outdoor fresh air and wet direct evaporating-cooling filler 7 after pre-cooling carry out directly
Evaporation cooling, temperature continue to be admitted to Indoor environment after reducing, and extra water flow returns to water storage on direct evaporating-cooling filler 7
It is continued cycling through in case 23.
