The specific embodiment
Introduce the utility model in detail below in conjunction with the drawings and specific embodiments:
As depicted in figs. 1 and 2, a kind of preferred embodiment that provides for the utility model, a kind of integrated freezing unit, comprise host groups 1 and evaporimeter 2, both are fixed together by connecting rod 3, therefore, both are fixed together and form integrated connection, move and install all very convenient, saved a large amount of time.During installation, earlier on a wall of freezer, offer through hole, then connecting rod 3 is arranged in the through hole, make host groups 1 be fixed in the outside of freezer wall, evaporimeter 2 is fixed in the inboard of freezer wall, just shortened the length of cold air path between host groups and the evaporimeter greatly, not only saved a large amount of tubing, made that also refrigeration improves greatly simultaneously.
Integrated freezing unit of the present utility model comprises refrigeration and hot gas defrost two systemic circulations.
Described host groups 1 comprises a cabinet 4, the condenser 6 that this cabinet inner bottom part is provided with, the top of this condenser is installed with a compressor 5, gas-liquid separator 7 and electric cabinet 8, wherein the high-pressure side 51 of compressor is communicated with by high-voltage tube 52 with an end of described condenser, the other end of described condenser is communicated with an end of described evaporimeter 2 by an input pipe 21, be in series with device for drying and filtering 211 and expansion valve 213 on the described input pipe successively, the other end of described evaporimeter is communicated with gas-liquid separator 7 in being located at cabinet 4 by an efferent duct 22, and this gas-liquid separator is communicated with the low-pressure end 53 of described compressor by a low-voltage tube 54.These structures have constituted described kind of refrigeration cycle.
The operation principle of above-mentioned kind of refrigeration cycle is: the refrigerant gas of low-temp low-pressure is entered in the compressor by the low-pressure end 53 of described compressor 5, through becoming the gas of HTHP after the compressor effect, after coming out by the high-pressure side 51 of compressor then through the effect of described condenser 6, the condensation of gas release heat is to external environment, become the refrigerant liquid of high pressure after the condensation of gas of HTHP, then enter into the device for drying and filtering 211 on the input pipe 21, may contain a spot of moisture and incoagulable gas in the cold-producing medium and pass through the effect of device for drying and filtering moisture absorption, make incoagulable gas filter out, then enter described expansion valve 213, the refrigerant liquid of high pressure is become the refrigerant liquid of low pressure by the expenditure and pressure effect of expansion valve, the refrigerant liquid of low pressure just enters in the evaporimeter 2 then, evaporation makes cold air enter into freezer from air outlet 9 in evaporimeter, in becoming the process of gas, evaporation absorbs heat, thereby the heat in the freezer is taken away, to reach the effect of refrigeration; The refrigerant gas that evaporation becomes gas comes out to enter into described gas-liquid separator 7 along efferent duct 22 from the other end of evaporimeter, owing to may have still unevaporated liquid in a small amount, the effect of gas-liquid separator is exactly that the impurity such as liquid that are mixed in the refrigerant gas are separated, enter in the compressor through the low-pressure end 53 of the gas after the gas-liquid separation from compressor 5, finish a kind of refrigeration cycle, the gas that becomes HTHP through the effect of compressor comes out from high-pressure side 51 again, thereby carries out next kind of refrigeration cycle.
After above-mentioned refrigeration system is moved a period of time, can be above the described evaporimeter 2 because temperature crosses low the situation frosting that occurs freezing, can make the interior heat exchange deleterious of evaporimeter and freezer like this, heat exchange is thorough inadequately, influence refrigeration, just need carry out defrost this moment.Therefore, some parts in cooling cycle system, have been added again, between described device for drying and filtering 211 and expansion valve 213, be provided with a refrigeration magnetic valve 212, the high-voltage tube 52 of described compressor 5 is provided with an arm 521 that directly is communicated with described evaporimeter 2, and this arm is provided with a defrosting magnetic valve 522.In kind of refrigeration cycle, at first open described refrigeration magnetic valve 212, close defrosting magnetic valve 522.
And the operation principle of described hot gas defrost circulation is: at first close refrigeration magnetic valve 212, open defrosting magnetic valve 522, the gas of the HTHP that is come out by described compressor 5 high-pressure sides 51 is flowed directly in the described evaporimeter 2 through the defrosting magnetic valves by arm 521, condense in frost above the evaporimeter absorb high temperature refrigerant gas heat and melt, absorb when melting the temperature of refrigerant gas is lowered, getting back to described gas-liquid separator 7 through the refrigerant gas of supercooling gets back in the compressor 5 from low-voltage tube 54 again, promptly finish a hot gas defrost circulation, through becoming the gas of HTHP after the effect of compressor, carry out next hot gas defrost circulation again.
Be provided with an electric cabinet 8 in the described cabinet, described hydrojet magnetic valve 222, defrosting magnetic valve 522 and pressure controller 41 all are electrically connected with described electric cabinet.Be communicated with by a sparge pipe 221 between described input pipe 21 and the efferent duct 22, and this sparge pipe is provided with a hydrojet magnetic valve 222, this hydrojet magnetic valve is in closed condition usually, when the sensor sensing in the electric cabinet 8 surpasses setting value to the temperature of described compressor 5 high-pressure sides 51, control panel in the electric cabinet will be controlled the hydrojet magnetic valve automatically and open and work, the refrigerant liquid that the described condenser 6 of process cools down will be got back to the high-pressure side 51 of compressor 5 by sparge pipe 221, thereby cooling compressor plays the effect of overtemperature prote; Also be provided with a pressure controller 41 in the described cabinet 4; this pressure controller is provided with two tubules 50 that are communicated with the high-voltage tube 52 and the low-voltage tube 54 of described compressor 5 respectively; this pressure controller plays the height pressure side of protection compressor, and it is low excessively to prevent that high pressure from crossing high and low pressure.Described host groups 1 is provided with air outlet 9.Therefore, the very advantages of simple of this structural design, meet hommization.
