Abstract
The utility model discloses a refrigerator with cold air, comprising two evaporators. One is the freezing chamber evaporator which is arranged in a freezing chamber and is used for freezing food. The other is the cold air evaporator which is arranged in a cold air chamber and is used for cooling the air in the room. The freezing chamber is isolated with the cold air chamber through insulation materials. An electromagnetic valve is arranged between the two evaporators. The utility model can send cold air to rooms for adjusting the indoor temperature and meanwhile can refrigerate and freeze food.
Description
The utility model relate to a kind ofly both can refrigerate, frozen food, can produce the refrigerator of cold wind again.
The major function of existing refrigerator is refrigeration, frozen food, and function is more single, and the condensation of its cold-producing medium all is to adopt the natural wind condensation, because the heat conductivility of air is poor, condensation of refrigerant efficient is lower.The heat that refrigerator produces mainly by natural wind condensation coil pipe, compressor, utilizes the nature type of cooling to be lost to the room, and room temperature is raise to some extent, the power of refrigerator is big more, and the heat of generation is just many more, and room temperature is also high more, especially during the broiling summer, make the people feel uncomfortable.
The purpose of this utility model is for refrigerator increases a kind of new function, and it be in refrigeration, in the frozen food, can send cold wind to the room, makes the room cool and comfortable that becomes, and improves the condensation efficiency of cold-producing medium simultaneously, stops refrigerator to dispel the heat to the room.
The purpose of this utility model is achieved in that
Two evaporimeters are housed in refrigerator, and one is freezer evaporator, is contained in refrigerating chamber, is used for the refrigerator frozen food; Another is the cold wind evaporimeter, is contained in cold air chamber, is used for the cool room hot-air.Separate with insulation material between refrigerating chamber and the cold air chamber, be connected with solenoid electric valve between two evaporimeters, it is positioned at cold air chamber's one side, link to each other the flow direction and the assignment of traffic in two evaporimeters of control low temperature, low-pressure, liquid refrigerant with cold wind evaporimeter feed tube and freezer evaporator outlet.Be surrounded by insulation material around cold wind evaporimeter feed tube, solenoid electric valve and the cold air chamber, the air inlet of cold air chamber and air outlet are equipped with the insulation sealed door, can stop scattering and disappearing of cold.Blower fan is housed in the cold air chamber, makes the room hot-air by cold air chamber, cooling is cooled.Compressor inleting pipe links to each other with the outlet of cold wind evaporator refrigerant, solenoid electric valve, and outlet capillaceous links to each other with import, the cold wind evaporimeter feed tube of freezer evaporator.When use in refrigerator during in frozen food, solenoid electric valve is in off-position, and low temperature, low-pressure, liquid refrigerant all flow through freezer evaporator, and the heat of absorbing food product is evaporated to gaseous refrigerant, by solenoid electric valve, enters into compressor inleting pipe; When refrigerator when the room send cold wind, the solenoid electric valve energising starts, most of low temperature, low-pressure, liquid refrigerant enter into the cold wind evaporimeter, absorbed the heat of hot-air, become gaseous refrigerant, flow in the compressor inleting pipe again, and small part low temperature, low-pressure, liquid refrigerant enter into freezer evaporator, the heat of absorbing food product is evaporated to gaseous refrigerant, passes through solenoid electric valve, also flow in the compressor inleting pipe, therefore refrigerator is when sending cold wind, also can frozen food, guarantee that food can Yin Wendu raise and goes bad.
Natural wind condensation and water condensation dual mode are adopted in the condensation of refrigerator refrigerant, at the natural wind condensation coil pipe of refrigerator condenser are housed topmost, and subcooler is being housed bottom, and condenser, subcooler are a kind of water coolers of water condensating refrigerant.The refrigerant inlet of condenser links to each other with compressor exhaust pipe, and outlet links to each other with natural wind condensation coil pipe.The refrigerant outlet of subcooler links to each other with device for drying and filtering, and import links to each other with natural wind condensation coil pipe.Be with cooling jacket on compressor case, it is movable, can take down from shell.When the running water temperature is lower than air themperature, can be used as cooling water uses, one of cooling water inlet pipe is terminated on the water supply pipe, the other end is connected on condenser, on the water inlet of subcooler and compressor cooling jacket, one of cooling water outlet pipe terminates at condenser, on the delivery port of subcooler and compressor cooling jacket, the other end is connected on the cool-bag, like this, behind the connection running water, running water enters into condenser, in subcooler and the compressor cooling jacket, with cold-producing medium, compressor carries out heat exchange, absorbed the heat that cold-producing medium and compressor produce, temperature raises, and becomes hot water, by cooling water outlet pipe, flow in the cool-bag.The high temperature, the high-pressure gaseous refrigerant that come out from compressor at first enter into condenser by compressor exhaust pipe, are condensed into lower liquid state of temperature or gaseous refrigerant by running water, and heat is absorbed by running water, have stoped the heat radiation of cold-producing medium to the room; Again by natural wind condensation coil pipe, enter into subcooler then, cooled off again by running water, temperature is lowered again, and is last, absorbs moisture and impurity through device for drying and filtering again, enters into capillary by throttling.Because the running water temperature is lower than air themperature, in subcooler, the condensation temperature of cold-producing medium is dropped to is lower than air themperature, and adopting the natural wind condensation, condensation temperature can not be lower than air themperature, according to refrigeration principle as can be known, condensation temperature is low more, and condensation efficiency is high more, and compressor power consumption is few more.
Magnetic valve is housed on cooling water inlet pipe, can controls the supply of running water automatically, when compressor operating, need running water cooling compressor, condensating refrigerant, the magnetic valve energising is opened, and supplies water; When compressor shutdown, do not need the running water cooling, the magnetic valve outage is closed, and stops to supply water, and realizes that the method that both work asynchronously is: two power lines of magnetic valve are connected on the two ends that compressor electric motor moves winding, and making both is in parallel the electrical connection.
Be surrounded by insulation material on condenser, subcooler, device for drying and filtering, the compressor exhaust pipe, stop heat to scatter and disappear, heat-insulation layer is movable, during without the water-condensed refrigerating agent, heat-insulation layer is dismantled, and is beneficial to heat radiation.
Cooling water inlet pipe, cooling water outlet pipe all are utilidors, carry out heat exchange to stop running water and air.
When without the water-condensed refrigerating agent, can use natural wind condensation coil pipe condensating refrigerant separately, its shape and area of dissipation can satisfy the condensation requirement of cold-producing medium.
When refrigerator send cold wind, must adopt the water condensation mode, running water can be collected into the room heat absorption in the cool-bag, and not dispel the heat to the room like this.
Can find out by such scheme,, reduce the condensation temperature of cold-producing medium, improve condensation efficiency, stop the heat radiation of refrigerator to the room owing to adopted the water condensation mode; Compressor uses water cooling, and good heat dissipation effect has been protected compressor; Simultaneously, available refrigerator send cold wind to the room, makes air nice and cool, and this is the existing not available function of refrigerator.Though use running water to make cooling water, use back water quality not contaminated, can be used for having a bath etc., can reuse, can not cause waste.
