Described heat preservation hot water pot stores the hot water heated by solar thermal collector, and it is for household use or be evaporator with heat pump heat supply that hot water outlet connects attemperater; Air heat exchanger is had in hot-water cylinder, air after the dedusting of absorption dedusting tank heats in hot-water cylinder, be contained in warm and humid sensor on hot-water cylinder outlet thermal insulation wind pipe and detect the temperature and humidity of the rear air of heating, and data are transferred to centralized displaying operator, can be directly extremely more indoor by thermal insulation wind pipe when the air themperature heated in hot-water cylinder is higher, hot water is directly for household use without evaporimeter; When temperature is not high, the air after heating heats through the evaporimeter of heat pump again, and the hot water in hot-water cylinder also flows into heat supply in evaporimeter, and these operations are arranged through control PLC control valve to realize according to user by centralized displaying controller.
Described absorption dedusting tank has two adsorption tanks, and alternating sorbent regenerates.Adsorption tanks inside stuffing matter is activated carbon, and after circulating fan starts, fans entrance there will be negative pressuren zone, and outside air will be inhaled into, and the air of suction enters from adsorption tanks air intake, by active carbon bed dedusting.After an adsorption tanks absorption is saturated, just switch another adsorption tanks work, adsorb saturated adsorption tanks and carry out desorption and regeneration, desorption technique first passes into clean water, then pass into high-temperature vapor.
Described cold water tank cools the hot-air of discharging in room, absorbs the heat of discharging in air, enters solar thermal collector heating water tanks again after making cold water carry out preheating, improves energy utilization efficiency.
Described centralized displaying operator can gather the data of airduct and indoor warm and humid sensor collection, adds negative ion device and sends instruction, realize full-automatic operation to PLC control valve, compressor, circulating fan and humidification.
The present invention has the following advantages:
Native system capacity usage ratio, operating automation degree is high, and it takes full advantage of this energy that is clean, environmental protection of solar energy and carries out indoor heating, and solar energy and heat pump complementary combinations, solves the deficiency relying on separately solar heating; Native system not only heats to indoor, is combined simultaneously, is intended to improve indoor environmental quality with air exchange system, improves indoor air quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of patent of the present invention;
In figure: 1-cold water tank, 2, the warm and humid sensor of 12-, 3-expansion valve, 4-evaporimeter, 5-compressor, 6-condenser, 7-humidification, add negative ion device, 8-circulating fan, 9-PLC control valve, 10-thermal insulation air channel, 11-attemperater, 13-heat preservation hot water pot, 14-flat-plate solar heat collector, 15-solar thermal collector support, 16-hand-operated valve, 17-adsorbs dedusting tank, 18-centralized displaying operator
Detailed description of the invention
With reference to Fig. 1, the indoor heating scavenging utilities containing solar energy and heat pump that patent of the present invention provides, outside air first heats at heat preservation hot water pot 10 through the dedusting of absorption dedusting tank 7, again or after heat pump condenser 6 heats, blows into indoor heating by circulating fan 6 and change room air; Indoor hot-air is out discharged after cold water tank 1 cools; Water in water pipe first absorbs waste heat preheating in hot-air, is stored in heat preservation hot water pot 13 after heating after solar thermal collector 15 at cold water tank 1.
Heat pump cycle: gaseous state heat pump fluid (cold-producing medium) heat temperature raising in compressor 5, flow through condenser 6 heat release and be condensed into liquid state, heat passes to the air of thermal insulation wind pipe 10; Liquid refrigerant, through expansion valve 3 reducing pressure by regulating flow, absorbs the heat from the warm water in heat preservation hot water pot 13 in evaporimeter 4, and evaporation is converted into low-temp low-pressure gaseous state, again enters compressor, completes and once heat circulation.Constantly circulate with this, realize heating circulation.
The course of work of patent of the present invention: when interior sensor detects indoor temperature lower than user's set temperature, centralized displaying operator will send instruction to circulating fan, outside air will be inhaled in adsorption tanks, air after the dedusting of absorption dedusting tank heats in hot-water cylinder, be contained in warm and humid sensor on hot-water cylinder outlet thermal insulation wind pipe and detect the temperature and humidity of the rear air of heating, and data are transferred to centralized displaying operator, can be directly extremely more indoor by thermal insulation wind pipe when the air themperature heated in hot-water cylinder is higher, hot water is directly for household use without evaporimeter, when after heating in hot-water cylinder, air themperature is not high, heat pump cycle starts, centralized displaying controller can send instruction to PLC control valve, and the evaporimeter of air flow over heat pump is heated again, and it is for household use again that the warm water in hot-water cylinder first flows into heat supply in evaporimeter.Enter indoor air and can add negative ion device interpolation anion through humidification, when indoor humidity is less, this device also can increase the humidity of air.The air of indoor discharge flows in cold water tank and absorbs waste heat.
In this drying facility, energy-dissipating device is circulating fan and compressor, and its mean power is 0.15KW.The maximum feature of inner circulation type heat pump increases efficiency at double, consumes the transferable heat being equivalent to 6.46 times of electric energy of 1KW/h in theory, than directly increasing efficiency 6.46 times with electrical heating class.Actual value is nearly 1/2 of theoretical value.It is 90 DEG C that experiment records solar thermal collector heat-absorbent surface mean temperature, and the mean temperature of cover glass inner surface is 50 DEG C, and heat collector effectively recepts the caloric as 428W/m in theory 2, efficiency is 57%.
