Abstract
The utility model provides an open-type refrigerating system. The open-type refrigerating system uses water which does not pollute environment or water and liquid which is added with small quantity of alcohol as refrigerant. The circulating mode of the utility model is different from the closed circulation of evaporation, compressing, liquefying, and cooling processes used by the existing refrigerating systems. The refrigerant of the open-type refrigerating system is used once in the refrigerating process, and is directly exhausted into atmosphere after evaporation and heat absorbing. With the advantages of low power consumption, simple structure, low cost, non environmental pollution, etc., the utility model is an economical and practical device for cooling and dehumidifying a room in summer.
Description
The utility model relates to refrigerating system.
Existing refrigerating system adopts the mode of refrigerant cycle, makes refrigerant evaporation heat absorption, then a working cycles is finished in gaseous refrigerant compression, liquefaction, cooling.Mainly there is following shortcoming in this type systematic: 1, the refrigerant that is adopted mostly is environmentally harmful material, for preventing its leakage, the sealing of whole system, cooperation, intensity etc. are required high, thus to material selection, to cause the requirement of making, assembling just high, this just makes the product cost height, has limited its application scenario.2, energy consumption height.For making the refrigerant liquefaction after the evaporation, compression power need be provided, according to the law of thermodynamics, this part energy will be converted into the heat merging that absorbs in heat and the refrigeration processes and be present in the refrigerant, in cooling procedure, be subjected to the cooler environment Temperature Influence again, make in the refrigerant after-heat enter next circulation, thereby refrigerating capacity is reduced, energy consumption increases.3, owing to can not guarantee the positive confinement of system sometimes, cause refrigerant to leak and the harm environment.
The purpose of this utility model is to provide a kind of refrigerating system that can overcome above-mentioned shortcoming to a great extent.
The utility model provides a kind of open type refrigerating system, the same with existing closed-cycle refrigeration system, also be to utilize the evaporation heat absorption of the refrigerant in it to make by the refrigeration space to lower the temperature through heat exchanger, it is characterized in that: said refrigerant is not environmentally hazardous easy evaporating liquid, it is contained in one or more and places by the heat exchanger in refrigeration space, said heat exchanger is provided with the liquid filling hole that attaches refrigerant and is used to observe the refrigerant marking device of liquid level in it, one place by outside the refrigeration space or among air extractor be connected with said heat exchanger sealing ground through pipeline, the gas outlet of this air extractor is positioned at by outside, refrigeration space, and the refrigerant after the evaporation enters atmosphere through this gas outlet.
Because the surface temperature of heat exchanger and connecting pipe is more much lower than ambient temperature, contained humidity will be an aqueous water in these surface condensations in the surrounding environment, so also played the effect of cooling simultaneously.For collecting these condensate water, the gatherer of the lip-deep condensate water of collection its each can be set in the bottom of heat exchanger.
For saving the energy and adapting to different temperature adjustment needs, can regulate the speed of evacuation and the start/stop time of air extractor, also can in this refrigerating system, install the automatic temp controller that adopts in the existing enclosed refrigerating system.
Said refrigerant can adopt water or add the water of a small amount of alcohol.
This open refrigerating system that the utility model provides has overcome the shortcoming of foregoing existing enclosed refrigerating system, and it is simple in structure, cost is low, and energy consumption is low, and does not endanger environment.
Accompanying drawing is the schematic diagram of this system.Each label is represented among the figure:
1--heat exchanger 2--refrigerant adds the heat absorbing sheet of the gas outlet 8--condensate collector 9--heat exchanger of hole 3--refrigerant 4--refrigerant liquid level height marking device 5--air extractor 6--connecting pipe 7--air extractor
The applicant once carried out experiment with following embodiment:
As air extractor, its speed of exhaust is 2 liters/second with the 370W rotary-vane vaccum pump, and maximum vacuum 10mm mercury column is used 1M
2Panel radiator is done connecting pipe as cryogen vessel (heat exchanger) with the welding steel pipe of 20 millimeters of internal diameters, with the water that adds a small amount of alcohol as refrigerant.Cryogen vessel (heat exchanger) is installed in 10M
2On the wall in room, air extractor (vavuum pump) is installed in outdoor.Open air extractor, through refrigeration in 20 minutes, room temperature is reduced to about 24 ℃ by 32 ℃, and (this moment, the heat-exchanger surface temperature was 10 ℃, and indoor air humidity reduces to 70% by 85%.
Claims (5)
