Temperature automatic test controller 18 possesses and can send instruction control air-conditioning according to setting automatic detected temperatures, realizes freezing, heats, air cleaning, renews the function of wind.This temperature automatic test controller 18 is made up of temperature detection sensor user instruction setting apparatus and microcomputer controller.Temperature sensor is two, one is installed in air inlet, another and user instruction setting apparatus are positioned on indoor, microcomputer controller is installed in the temperature automatic test controller 18, temperature sensor, be connected with lead between user instruction setting apparatus, air intake machine 3, air exhauster 16, electric heater unit 5, negative oxygen ion generator 5 and the temperature automatic test controller 18, temperature automatic test controller 18 be installed in electric heater unit 5 above.
Described air intake machine 3 and air exhauster 16 and pump motor 7 can be alternating current generators, also can be direct current generators.
The course of work and the principle of utility model patent are as follows:
1, when indoor and outdoor temperature all lower, and when need improving indoor temperature, can send instruction by temperature automatic test controller 18 by setting the temperature value that need reach, make 3 work of air intake machine, start electric heater unit 5 simultaneously, the atmosphere temperature rising that allows into, when temperature reached set temperature value, temperature automatic test controller 18 can send instruction, stop the temperature function that adds of electric heater unit 5, only keep air intake machine 3 and 6 work of water evaporation for cooling heat exchanger.Make the indoor-outdoor air exchange reach heat insulation function by water evaporation for cooling heat exchanger 6 simultaneously, make indoor temperature constant.Longer when running time, indoor temperature decreases, and the temperature automatic checkout system restarts electric heater unit 5 and heats up, reciprocation cycle like this, the interior temperature constant of holding chamber.
2, all higher when indoor and outdoor temperature, when needing refrigeration cool-down, can send instruction by temperature automatic test controller 18 and make water sprinkler system 19 work by setting the temperature value that need reach.Water pump 7 running enters spray with the pressurization of the water in the water tank 8 and chews 9 and chew 9 by spray and be sprayed onto equably on the water evaporating heat exchanger 6 appearance capillary suction nonwoven 26.Do not flowed in the ponding dish 11 and get back to water tank 8 by the water of capillary nonwoven 26 absorption.Then, control system starts air exhauster 16, because of suction function, indoor air is entered the outer gas flow passage 24 of water evaporation for cooling heat exchanger 6 by indoor air inlet, because the evaporation of the water on the capillary nonwoven 26 on the mobile heat exchanger 6 that evaporates the water of air, taken away by flow air, because evaporation of water must absorb the principle of a large amount of heats, can make hot water sweat cooling heat exchanger 6 and air cooling-down, gas in the outer gas flow passage 24 after the cooling again and the outdoor fresh air of coming in the internal layer gas channel 25 heat exchanges take place by the heat exchanger plates between the ectonexine gas channel 23, make gas in the internal layer inlet chamber become low temperature, healthy, fresh comfort air.Simultaneously, because the suction function of air exhauster 16, the damp atmosphere in refrigerated heat exchanger 6 outer layer channels 24 that evaporate the water is discharged in the outdoor environment, reaches air exchange, the purpose of refrigeration.Water evaporation for cooling heat exchanger 6 outer ripple heat-conducting plates 21 are set to corrugated, and purpose is to strengthen disengagement area and heat exchange area, improves the heat exchange effect.When temperature dropped to setting value, water sprinkler system 19 stopped water spray, and air exhauster 16 is still worked, and the refrigerated heat exchanger 6 that evaporates the water continues operation, and the air of indoor extraction and outdoor air of coming in carry out heat exchange, reach heat insulation effect.After operation a period of time, indoor temperature raises to some extent, and temperature automatic test controller 18 can send instruction again and carry out the water spray, realizes above water evaporation for cooling function.So, reciprocation cycle has realized the function that the air-conditioner refrigeration is incubated.
3, relatively poor when air quality, in the time of need carrying out sterilizing, can carry out the air aeration clearing according to setting, send the air cleaning instruction by temperature automatic test controller 18, start negative oxygen ion generating device 4.Simultaneously, start air exhauster 16 or air intake machine 3 and renew wind.The fresh air of coming in can be killed bacterium and the virus that contains in the air under the effect of negative oxygen ion, the content that increases oxygen simultaneously enters into indoor, and indoor ropy air can be discharged in the outdoor environment.Can under air conditioner heat-production, refrigeration work mode state, carry out synchronously according to setting this function.
Advantage of the present utility model and good effect: simple in structure, refrigerating/heating is effective, does not use powerful compressor, only uses blower fan, and energy consumption is the 10%-50% of traditional air-conditioning under the condition of identical refrigeration, than traditional air conditioner energy saving 50%-90%.Owing to do not use parts such as compressor, condenser, expansion valve, radiator, relatively low cost of manufacture.Water is as refrigerant, non-environmental-pollution; The humid air that is produced by water evaporation for cooling has been discharged to outdoor, can not increase the humidity of room air, simultaneously because the effect of negative oxygen ion, and the function that renews wind has guaranteed the quality of room air and fresh.Favourable health, the setting of temperature automatic detection and control system make the utility model air-conditioner automaticity height easy to operate.
