Abstract
The utility model relates to a vacuum refrigerator, which is designed for reducing the compressor power of a refrigerator of the same volume and the same magnitude. The utility model is characterized in that a refrigerating system is an airtight circulation system which is composed of an evaporator, a double point control double channel temperature vacuum valve, an air tank, a pressurizing tank, and a compressor. The refrigeration system of the utility model has the advantages of simple structure and stable performance; the power consumption of the compressor can be greatly reduced by more than 50 percents, and cost of the refrigerator can be reduced by more than 50 percents.
Description
Technical field
The utility model relates to a kind of vacuum type refrigerator that designs for the compressor horsepower that reduces the equal star of equal volume.
Background technology
Refrigeration plants such as common in the market refrigerator and refrigerator-freezer, most vapor compression type refrigerating systems that adopt, this system is that the mechanical compress with compressor is a power, cold-producing medium is through the high temperature condensation, high pressure throttling, low pressure evaporation, be converted into gaseous state by liquid state, be converted into by gaseous state again that cyclic process that liquid states of matter changes realizes freezing.Its whole circulation system mainly is made up of 4 links, promptly compresses link, condensation link, throttling link, evaporation link.The evaporation link is that the liquid refrigerant of low pressure is vaporized in evaporimeter, becomes the process of low pressure gaseous state refrigeration.This process makes by the heat that absorbs surrounding space on the one hand that refrigerator is freezing, the refrigerating chamber refrigeration, and the temperature of the cold-producing medium of gaseous state itself raises on the other hand, and this moment, its obtained (i.e. absorption) heat.The compression link mainly is that the running by motor comes the work of drive compression machine, produces compression stress, makes the low pressure that enters compressor, and low-temperature refrigerant becomes the heat steam of HTHP being compressed the utmost point in the short time.At this moment, it has obtained the heat that the external force work done transforms again.The condensation link is the liquefaction process of high temperature, high-pressure gaseous refrigerant.Compressed machine compresses and the superheated vapor of discharge, through external condenser, discharges the total amount of heat that obtains previously, make cold-producing medium become cold highly pressurised liquid, the throttling link is to make the high pressure liquid refrigerant that becomes low temperature, through expansion valve (capillary) throttling, in flowing, owing to be obstructed pressure is reduced gradually, at last return to original low pressure again, the cryogenic liquid state goes round and begins again, the circulation that does not stop reaches the purpose of refrigeration.This method is not owing to be directly to consume external work to form kind of refrigeration cycle, and the middle process that a power conversion is arranged, thereby its maximum shortcoming is exactly that energy consumption is big.After entering 21st century, people have begun to pay close attention to energy problem, and along with the raising of people's living standard, the consumption of refrigerator is increasing, and refrigerator has become the rich and influential family that energy consumes now.Change the current refrigerator refrigeration system and form structure, imperative.
Summary of the invention
The purpose of this utility model is exactly that the vacuum principle is applied in the refrigeration system of refrigerator, reduces same isometric(al) with this, and the power of the compressor of equal star reaches the effect of energy savings.
It is as follows that its refrigeration system of vacuum type refrigerator described in the utility model is formed structure:
It is an airtight circulatory system that partly is made of evaporimeter, air accumulator, pressurized canister, temperature vacuum valve, compressor etc. five, and the temperature vacuum valve is a binary channels valve, links to each other with air accumulator with evaporimeter respectively.The unlatching of temperature vacuum valve needs to satisfy simultaneously two conditions, and the temperature of evaporimeter reaches the setting release line, and air accumulator also will reach the vacuum of setting simultaneously, and not so the temperature vacuum valve just is in the binary channels closed condition.The service condition of compressor is not open when air accumulator has vacuum, reaches vacuum and shuts down.
Vacuum type refrigerator refrigeration system operation principle:
The temperature that is in evaporimeter when the temperature vacuum valve reaches the setting release line, and air accumulator is not when having vacuum, and the temperature vacuum valve still is in the binary channels closed condition.Service condition because of compressor is that air accumulator does not have the vacuum unlatching again, so after the compressor energising, promptly begin air accumulator is vacuumized, gaseous refrigerant in the air accumulator is compressed in the pressurized canister, when the air accumulator vacuum reaches design vacuum, the temperature that adds evaporimeter again reaches when setting release line, the temperature vacuum valve is opened, and compressor quits work.Compressed refrigerant is ejected into gasification refrigeration in the evaporimeter by the temperature vacuum valve in the pressurized canister.Because of air accumulator is in vacuum state is negative pressure, and gaseous refrigerant is inhaled in the air accumulator by the temperature vacuum valve.After the pressure of pressure in the air accumulator and evaporimeter maintained an equal level, the temperature vacuum valve cut out because of having lacked a unlocking condition.Refrigerator is in keeping warm mode.At this moment air accumulator does not have vacuum, and the compressor energising promptly begins air accumulator is vacuumized.At this moment the temperature vacuum valve is just waiting for that the temperature rising of evaporimeter reaches release line and air accumulator reaches the vacuum unlatching.And so forth, the vacuum type refrigerator has just been finished refrigeration.
That the refrigeration system of vacuum type refrigerator described in the utility model is formed is simple in structure, stable performance, can reduce the energy consumption of compressor significantly, reduce the discharging of nuisance, make full use of the energy, the utility model refrigeration system is compared with former freon compressor refrigeration system, but energy savings is more than 50%, and the refrigerator cost can reduce more than 50%.
