Specific embodiment
With embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings:
With reference to Fig. 3 Fig. 4: brooder air dewetting energy saver, include housing (1) and be arranged at the heat exchange inside housing (1) Device (2) it is characterised in that: is divided into two paths (a) not connected and that air circulation can be connected and logical inside heat exchanger (2) Road (b).The path (a) of heat exchanger (2) carries out the circulation of room air, is furnished with the indoor fan (3) of air draught or blowing, makes interior Air flows in heat exchanger (2) path (a).The path (b) of heat exchanger (2) carries out outdoor air flow, is furnished with air draught or blows The outdoor fan (4) of wind, makes outdoor air flow in heat exchanger (2) path (b).Heat exchanger (2) path (a) bottom is water receiving Box (5), water spilage tray (5) connects drain pipe (6) and discharges condensed water, is provided with temperature controller (7), temperature controller (7) on housing (1) simultaneously There are indoor temperature transmitter (8), outdoor temperature sensor (9), indoor humidity sensor (10).
The operation principle of the present embodiment: brooder air dewetting energy saver, including housing (1) be arranged in housing (1) The heat exchanger (2) in portion it is characterised in that: be divided into inside heat exchanger (2) two not connected and the logical of air circulation can be connected Road (a) and path (b).The path (a) of heat exchanger (2) carries out the circulation of room air, is furnished with the indoor fan of air draught or blowing (3) room air, is made to flow in heat exchanger (2) path (a).The path (b) of heat exchanger (2) carries out outdoor air flow, joins There is the outdoor fan (4) of air draught or blowing, so that outdoor air is flowed in heat exchanger (2) path (b).Heat exchanger (2) path (a) Bottom is water spilage tray (5), and water spilage tray (5) connects the condensed water that drain pipe (6) is discharged, and housing (1) is provided with temperature controller simultaneously (7), temperature controller (7) has indoor temperature transmitter (8), outdoor temperature sensor (9), indoor humidity sensor (10).Described warm Canopy air dewetting energy saver outdoor temperature sensor (9) detection outdoor temperature be less than 0 DEG C when, indoor temperature transmitter (8) Detection indoor temperature be higher than 20 DEG C, indoor humidity sensor (10) detection humidity be higher than 65% when, indoor fan (3) and outdoor wind Work opened by machine (4), and the outdoor air flowing through in heat exchanger (2) path (b) is less than 0 DEG C, flows through in heat exchanger (2) path (a) Room air be higher than 20 DEG C, now two strands of air carry out conduction of heat by heat exchanger (2) due to the temperature difference.Temperature when heat exchange Drop under room air dew point, room air condensed water is discharged, condensed water is discharged to water spilage tray (5) under gravity, finally leads to Cross drain pipe (6), be discharged to appointed place, reach the purpose reducing room air water capacity.When humidity reaches target setting value, By autostop.Advantage: when outdoor temperature is less than 0 DEG C, brooder indoor/outdoor temperature-difference big it is ensured that indoor temperature minimum change In the case of, timely and effective discharge the condensed water of air in booth, keep in booth rationally relative humidity, beneficial to plant, fruit and vegerable etc. The growth of plantation product, prevents the pathological changes because the excessive generation of humidity is gone mouldy, the normal growth of impact crop.Utilize natural epidemic disaster in booth simultaneously Difference, its power consumption is low, more energy-conservation.
Compare with steam compression type dehumidifying mode, this brooder air dewetting energy saver total energy-conservation expense includes the section of cost The energy-conservation expense of about expense and operating electricity consumption, the energy-saving benefit estimation of this brooder air dewetting energy saver:
Taking the dehumidifier of 3 steam compression type dehumidifying modes as a example, the size of brooder: long 60 meters, wide 4 meters, high 2.5 meters, Spatial volume is: 60 × 4 × 2.5=600 cubic meter.
Table look-up: air parameter,
25 DEG C of atmospheric density ρ: 1.173 (kg/m3)
15 DEG C of atmospheric density ρ: 1.218 (kg/m3)
When outdoor temperature is less than 0 DEG C, 12.5 DEG C of theoretical mean temperature after its heat exchange is 25 DEG C less than room air 18 DEG C of dew point temperature value.
Refrigeration work consumption calculates: 600 × 1.173 × (73.6-36.5)/3600/3=2.417kw
The power consumption of brooder air dewetting energy saver is 0.5kw
Calculated according to above-mentioned parameter:
Reach same effect on moisture extraction, brooder air dewetting energy saver consumed power ratio steam compression type power is few: 2.417kw-0.5kw=1.917kw.It is to calculate for 100 days by winter time, daily operation 20 hours.Power cost saving is calculated as follows:
Year economize on electricity (spending)=1.917 kw × 20 hour × 100 day=3834kw h;
1 energy-conservation expense/year (first)=3834kw h × 0.52 yuan/degree=1993.68 yuan;
10000 energy-conservation expense/years (first)=1993.68 ten thousand yuan;
By 3 air-conditioning cost calculations, compressor, two devices etc. save 1000 yuan, use by 10 years, and Cost comparisons calculate such as Under:
1 cost savings expense/year (first)=1000 yuan ÷ 10 years=100 yuan/year;
10000 energy-conservation expense/years (first)=1,000,000 yuan;
Then, for steam compression type dehumidifying mode energy-conservation, use 10,000 brooder air dewetting energy savers permissible in year The social benefit of energy-conservation is 2093.68 ten thousand yuan/year.
This utility model brooder air dewetting energy saver belongs to air adjustment dehumidifying technology field, using such as warm Canopy, heliogreenhouse facility, make full use of the brooder of the mode of heatings such as solar energy, electric energy, boiler, carry out vegetable in cold district and get over Winter cultivates, spring autumn and winter farming and animal husbandry lagging facility.It is specially arviculture brooder, cultivating seeds brooder, seedling culture brooder, Brooder, flower culture brooder, Peasants Joy brooder etc. are fattened in the cultivation such as horse, sheep, pig, cattle, chicken, duck.
The explanation of above example is only intended to help understand method of the present utility model and its core concept.Should refer to Go out, for those skilled in the art, on the premise of without departing from this utility model principle, can also be to this Utility model carries out some improvement and modifies, and these improve and modification also falls into this utility model scope of the claims Interior.
