Description
Technical field
The present invention relates to a kind of defroster, especially relate to a kind of air-cooler energy-saving defrosting device based on charging capacitor.
Background technology
Air-cooler, is divided into refrigerating industry air-cooler and Household air cooler, and industrial air-cooler is generally used in freezer, Cold Chain Logistics refrigerating environment, and family expenses are again Water cooled air conditioners, is a kind of evaporation type cool-down ventilation machine group that integrates cooling, ventilation, dustproof, taste removal.
Air-cooler (vaporizing type air conditioner) cool principle is: in the time of fan operation, enter and in chamber, produce negative pressure, the machine outer air of making flows through the moistening wet curtain surface of porous forced the dry-bulb temperature of curtain air to be down to the wet-bulb temperature close to machine outer air, be that the dry-bulb temperature of air-cooler outlet is than the low 5-12 of outdoor dry-bulb temperature DEG C (xeothermic area can reach 15 DEG C), air is more xeothermic, its temperature difference is larger, and cooling-down effect is better.Because air is indoor from outdoor introduction all the time, (being at this time positive pressure system) is so can keep the fresh of room air; Simultaneously because this machine utilizes evaporative cooling principle, therefore there is the dual-use function (relative temperature can reach 75% left and right) of cooling and humidification, between weaving, knitting waiting for bus, use, not only can improve decreasing temperature and increasing humidity condition, and can also purify air, reduce pin and spin the pin wire broken rate in process, improve the quality of pin textile product.The surrounding of air-cooler (vaporizing type air conditioner) is equipped with and uses the cellular wet curtain of special material, has very large surface area, by water circulation system to the wet continuous humidification of curtain; In wet curtain air-cooler, efficient, low-noise energy-saving blower fan is housed, in the time of fan operation, the generation negative pressure of wet curtain air-cooler, the machine outer air of the making moistening wet curtain of porous of flowing through enters in machine, because evaporation of water on wet curtain absorbs heat, forces the air cooling-down of system through wet curtain.Because the water on wet curtain is to the air evaporation of the wet curtain of flowing through, increased the humidity of air, therefore wet curtain air-cooler has the dual-use function of decreasing temperature and increasing humidity simultaneously.
What in industry, commonly use is dry cold blower fan.It is the air that carrys out the outer forced flow of cooling tube by air by the evaporation row battalion in air-cooler.It is contained in to the terrace in freezer, is called console mode air-cooler; Be contained in storehouse top upper, be called ceiling mounting type air-cooler.
But being everlasting, air-cooler moves under the operating mode of easier frosting.To make that heat exchange thermal resistance increases, Efficiency Decreasing after air-cooler frosting, make thus that refrigeration system COP reduces, fan energy consumption increase etc.Therefore, timely and effectively air-cooler is defrosted extremely important.Defrost and mostly adopt electrically heated mode for the evaporimeter in air-cooler at present, but the method has the shortcomings such as defrosting energy consumption is large, the time is long, efficiency is low, and in defrost process, need the major part of rime ice to be melted into water, thus defrost, and this is a larger energy consumption; On the other hand, electrical heating wire, to the heat of storehouse radiation, becomes again extra thermic load when refrigeration machine freezes next time.
Summary of the invention
Object of the present invention is exactly to provide a kind of air-cooler energy-saving defrosting device based on charging capacitor in order to overcome the defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions: a kind of air-cooler energy-saving defrosting device based on charging capacitor, be arranged on the pipeline of air-cooler, it is characterized in that, described pipe surface arranges a layer insulating, this surface of insulating layer plating film resistor, this resistance and Capacitance parallel connection are connected on power supply, and are provided with the switch module b that controlling resistance is switched on or switched off, and the switch module a that is switched on or switched off of control capacitance; Program control switch assembly a connects, and power supply is to capacitor charging, after charging finishes, and program control switch assembly a dead electricity, need to defrost time, program control switch assembly b connects, and electric capacity sparks, the frost layer inner surface heating of large electric current to resistive surface, is vaporized, and frost layer comes off.
