Abstract
The utility model discloses a refrigerating device of a fresh-keeping storehouse controlled by a low-temperature compressor. The refrigerating device comprises the low-temperature compressor and a condenser which are installed inside the free-keeping storehouse, and an evaporator installed indoors. The evaporator is communicated with the low-temperature compressor and the condenser through a liquid inlet pipe and a gas outlet pipe. The compressor and the condenser are connected with a refrigerating device controller. A shell body is arranged outside the evaporator, an air exhaust device is arranged on the top portion of the shell body, the air exhaust device is communicated with the inner portion of the shell body, a temperature sensor is further arranged inside the fresh-keeping storehouse, and the temperature sensor is connected with the refrigerating device controller. Due to the fact that the shell body is arranged outside the evaporator inside an existing refrigeration house in a sleeved mode, the air exhaust device is arranged on the top portion of the shell body and the temperature sensor is installed indoors, the refrigerating house provided with the low-temperature refrigerating device can be used for a 0 DEG C-7 DEG C fresh-keeping storehouse, and after the shell body outside the evaporator is taken down, the refrigerating house can also be used as a below-ten-DEG C fresh-keeping storehouse.
Description
Technical field
The utility model belongs to refrigerating plant, relates in particular to a kind of refrigerating plant that cryogenic compressor is applied to fresh-keeping warehouse.
Background technology
The cryogenic compressor refrigerating plant generally comprises and is installed in outdoor low temperature compressor, condenser and expansion valve and is installed in indoor evaporimeter.Whole refrigeration system is connected by circulation line, constitutes an airtight loop.Fill cold-producing medium in the pipeline.Compressor plays a part the conveying refrigerant gas of compression in refrigeration system, namely the low-pressure low-temperature gas that produces in the evaporimeter is sucked back, and is collapsed into high temperature and high pressure gas again and sends into condenser.Condenser is used for the high temperature and high pressure gas that compressor is pressed into is cooled off and condensation, under certain pressure and temperature, the gas liquefaction of HTHP is become normal temperature and pressure liquid.Expansion valve is installed between liquid reservoir and the evaporimeter, is a separation of system inner high voltage district and low-pressure area, and its effect is that highly pressurized liquid throttling is expanded, and becomes low pressure liquid, and it also is the outpost of the tax office of regulating and control refrigerant flow.In evaporimeter, the low pressure refrigerant after the throttling expansion absorbs heat and is evaporated to gas from storehouse, makes the storehouse temperature drop low, reaches the purpose of refrigeration.In whole refrigeration system, higher-pressure region and low-pressure area two parts are arranged, be the higher-pressure region from the active section of exhaust end before expansion valve of compressor; Active section to the compressor air suction end behind the self-expanding valve is low-pressure area; By exhaust gas pressure gage and this two-part pressure of pressure of inspiration(Pi) table difference approximate representation.Compressor plays action of the heart in whole refrigeration system, provide the process of energy compensating.Condenser and evaporimeter are two heat exchangers, and the former makes the gas heat release of high-pressure refrigerant, and is converted into liquid; The latter makes the liquid heat absorption of low pressure refrigerant, and is converted into gas.Cold-producing medium becomes the delivery vehicle of heat energy in the process that moves in circles.In whole process, also needing to have controller, controller is electrical connections, and controller is electrically connected with compressor and expansion valve respectively, according to indoor temperature, regulates compressor and expansion valve by adjustment control, thereby regulates temperature in the freezer.
Present low temperature compression refrigerating system, evaporimeter are to be directly installed in the freezer, the direct and storehouse inner air flow of evaporimeter, main suitable low-temperature cold store below-10 ℃.Being not suitable for 0 ℃ of-7 ℃ of fresh-keeping warehouse uses.
Same like this freezer can only be used as refrigerated products, and the time spent can not done the fresh-keeping warehouse use, is unfavorable for saving storehouse.
Summary of the invention
The purpose of this utility model is to overcome the refrigerating plant that above-mentioned deficiency provides a kind of cryogenic compressor control fresh-keeping warehouse.
For achieving the above object, the utility model is by the following technical solutions:
A kind of refrigerating plant of cryogenic compressor control fresh-keeping warehouse, comprise low temperature compressor reducer and the condenser that is installed in the fresh-keeping warehouse and be installed in indoor evaporimeter, evaporimeter is communicated with low temperature compressor reducer and condenser by feed tube and escape pipe, compressor is connected with the refrigerating plant controller with condenser, at the sheathed housing in evaporimeter outside, be provided with air exhausting device in case top, air exhausting device is communicated with enclosure interior, also be provided with temperature sensor in fresh-keeping warehouse, temperature sensor is connected with the refrigerating plant controller.
The refrigerating plant of above-mentioned cryogenic compressor control fresh-keeping warehouse, described air exhausting device is ventilating fan.
The refrigerating plant of above-mentioned cryogenic compressor control fresh-keeping warehouse, the control system of described ventilating fan is connected with the refrigerating plant controller.
Adopt technique scheme, the utility model has following advantage: a sheathed housing outside the evaporimeter in original freezer, add an air exhausting device in case top, the temperature sensor that indoor installation one is electrically connected with the refrigerating plant controller, the freezer of cryogenic refrigerating unit installation both can use as 0 ℃ of-7 ℃ of fresh-keeping warehouse like this.Take down the housing that is enclosed within the evaporimeter outside and can also do the use of freezer below-10 ℃.The utility model can make the freezer storehouse, according to the different product requirements of different times, can make fresh-keeping storehouse and use, and removing shell body, can to make freezing storehouse again used, reaches the effect that use more in a room.
