Description
Technical field
The present invention relates to a kind of defroster, especially relate to a kind of air-cooler energy-saving defrosting based on charging capacitor
Device.
Background technology
Air-cooler, is divided into refrigerating industry air-cooler and Household air cooler, industry air-cooler to be generally used for freezer, cold chain
In logistics refrigerating environment, domestic are again Water cooled air conditioners, are a kind of to integrate cooling, ventilation, dust-proof, taste removal
Evaporation type cool-down ventilation machine group.
Air-cooler (vaporizing type air conditioner) cool principle is: enters intracavity when fan operation and produces negative pressure, makes machine
The wet curtain surface that outer air flow crosses porous moistening forced the dry-bulb temperature of curtain air to be down to close to machine outer air
Wet bulb temperature, i.e. air-cooler outlet dry-bulb temperature lower than outdoor dry-bulb temperature 5-12 DEG C (xeothermic area up to
15 DEG C), air is the most xeothermic, and its temperature difference is bigger, and cooling-down effect is the best.It is from introduction room, outdoor all the time due to air
In, (being at this time positive pressure system) is so the fresh of room air can be kept；Simultaneously because this machine utilizes evaporation fall
Temperature principle, therefore have cooling and humidification dual-use function (relative temperature is up to about 75%), weaving, knitting
Use between waiting for bus, not only can improve decreasing temperature and increasing humidity condition, and air can also be purified, reduce the pin during pin spins
Wire broken rate, improves the quality of pin textile product.The surrounding of air-cooler (vaporizing type air conditioner) is equipped with using special type
The cellular wet curtain of material, has the biggest surface area, by water circulation system humidification continuous to wet curtain；In wet curtain
Air-cooler is built with efficient, low-noise energy-saving blower fan, when fan operation, and the generation negative pressure of wet curtain air-cooler, make outside machine
Air flows through in the wet curtain entrance machine that porous is moistening, owing in wet curtain, evaporation of water absorbs heat, forces system through wet curtain
Air cooling-down.Simultaneously because water in wet curtain is to flowing through the air evaporation of wet curtain, increase the humidity of air, because of
This wet curtain air-cooler has the dual-use function of decreasing temperature and increasing humidity.
Commonly use in industry is dry cold blower fan.It is to arrange battalion by air by the evaporation in air-cooler to come outside cooling tube
The air of forced flow.The terrace it being contained in freezer, is called console model air-cooler；It is contained on storehouse top, cries
Do ceiling mounting type air-cooler.
But air-cooler often runs under the operating mode being easier to frosting.Heat exchange thermal resistance will be made after air-cooler frosting to increase,
Efficiency reduces, so that the reduction of refrigeration system COP, fan energy consumption increase etc..Therefore, the most right
Air-cooler carries out defrosting extremely important.Carrying out defrosting for the vaporizer in air-cooler at present, it is electrically heated mostly to use
Mode, but the method has the shortcomings such as defrosting energy consumption is big, time length, efficiency are low, and need during defrosting
The major part of rime ice is melted into water, thus defrost, this is a bigger energy consumption；On the other hand, electrical heating wire
To the heat of storehouse radiation, become again extra thermic load when refrigeration machine freezes next time.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide a kind of based on charged electrical
The air-cooler energy-saving defrosting device held.
The purpose of the present invention can be achieved through the following technical solutions: a kind of air-cooler based on charging capacitor is energy-conservation
Defroster, is arranged on the pipeline of air-cooler, it is characterised in that described pipe surface arranges a layer insulating,
This surface of insulating layer plating film resistor, this resistance and electric capacity are connected in parallel on power supply, and are provided with control resistance connection
Or the switch module b disconnected, and control the switch module a that electric capacity is switched on or switched off；Program control switch assembly
A connects, and electric capacity is charged by power supply, after charging terminates, and program control switch assembly a dead electricity, when needing defrosting,
Program control switch assembly b connects, and electric capacity sparks, and the frost layer inner surface of resistive surface is heated by big electric current,
Being vaporized, frost layer comes off.
Described both ends of power tandem tap assembly a and current-limiting resistance R2 respectively, middle two branch roads in parallel, its
In a branch road be provided with electric capacity, another branch road is in series with switch module b, resistance and current-limiting resistance R2.
Described switch module a is made up of the relay coil KA1 connected and switch SB1；Described switches set
Part b is made up of the relay coil KA2 connected and switch SB2.
Compared with prior art, present invention defrost based on charging capacitor discharge and recharge mode, when electric capacity discharges, greatly
The inner surface of frost layer is heated by electric current so that it is melt, to gasification, the vapour pressure of inner surface and rime ice layer from
Recast use, frost layer comes off, and this invention is under the effect of big electric current so that frost layer inner surface transient evaporation, and without
Monoblock rime ice melts, and therefore, it can be greatly saved the energy of defrosting.
