Description

Using nature heat source to the freezer of air-cooler defrosting
Technical field
The present invention relates to Cold Chain Logistics freezing and refrigeration technical fields, and in particular to a kind of utilizes nature heat source to air-cooler The freezer of defrosting.
Background technology
In Cold Chain Logistics freezing and refrigeration field, cooling blower structure is compact, and cooling rate is fast, and cold interior temperature is uniform, and by Wide hair is applied in freezer, but the cold interior temperature of low-temperature cold store be down to 0 degree hereinafter, air-cooler heat exchange pipe surface frosting, shape At thermal resistance, heat transfer coefficient is caused to reduce, heat transfer temperature difference increases, and evaporating temperature reduces, and the pressure ratio of refrigeration compressor increases, refrigeration The runnability of system declines.Generally use such as electrical heating defrosting, need to arrange motor heat pipe, consume electric energy, hot gas defrosting System complex, same power consumption increases, and the temperature of China some areas external environment is higher, as Hainan, Guangzhou, Yunnan etc., External environment minimum temperature was ten several years throughout the year, summer temp higher, and the natural heat source that utilization is richly endowed by nature, abundant melts The frost layer for changing refrigeration system evaporator heat exchange pipe surface, can reduce the energy consumption of refrigeration system, energy saving.
Invention content
The purpose of the present invention is being directed to technological deficiency existing in the prior art, a kind of Cold Chain Logistics freezing and refrigeration neck is provided Domain using nature heat source to the freezer of air-cooler defrosting.
The technical solution adopted by the present invention to solve the technical problems is:
Using nature heat source to the freezer of air-cooler defrosting, including:
The freezer for the heat source air door that can be unlatched and closed, the inside of the heat source air door and installation are installed on the wall of side The open end in the air duct that open at one end, the other end in the freezer block is connected;Side installation is closely blocked in the air duct Air-cooler is equipped with preceding wind on the air duct side wall towards the air outlet side in the directions Ku Men of the air-cooler by preceding air door Door, the air-cooler are equipped with rear air door, institute on the air duct side wall of the air inlet side in the directions Ku Men by rear air door It states air-cooler and is separately connected refrigerant inlet pipe, refrigerant outlet pipe.
The air-cooler respectively press by the reducing pressure by regulating flow element through refrigerant inlet pipe, refrigerant outlet pipe and refrigeration system and refrigeration The entrance sleeve of contracting machine connects.
The air duct is the open at one end formed by thermal insulation board, the rectangular parallelepiped structure of other end closure.
The freezer is the three-dimensional shape formed by thermal insulation board.
The air-cooler is fixed on by the hanger at the top of air duct in the library of freezer.
The present invention using nature heat source to the freezer of air-cooler defrosting, utilize the higher natural air of ambient temperature Heat source melts the frost layer of refrigeration system evaporator heat exchange pipe surface, effectively reduces the energy consumption needed for refrigeration system defrosting, save energy Source.
Description of the drawings
Fig. 1 show the structural schematic diagram using nature heat source to the freezer of air-cooler defrosting of the present invention;
Fig. 2 is shown as the sectional view along A-A of Fig. 1.
Specific implementation mode
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2, using nature heat source to the freezer of air-cooler defrosting, including:
Heat source air door 1, air duct 2, air-cooler 3, fan 4, hanger 5, freezer body 6, preceding air door 7, rear air door 8, refrigerant into Pipe 9, refrigerant outlet pipe 10, library door 11.
The freezer body 1 is the three-dimensional shape being made of thermal insulation board, and left side wall offers air door aperture, close to freezer Hanger 5 is fixed at the top of back wall, preceding wall offers doorframe, is sealed with library door 11.
The air duct 2 is the rectangular parallelepiped structure that the open at one end being made of thermal insulation board, the other end block, close to blocking in end Air-cooler 3 is placed in portion, and open end is fixed in the air door aperture that left side wall offers, and edge is matched with the sealing of heat source air door 1 It closes, heat source air door 1 can be opened and closed.
The air-cooler can be fixed on by the hanger 5 across 2 top of air duct in the library, and be located at the position of nearly back wall, The air duct 2 of air-cooler air outlet side (towards the directions Ku Men) offers preceding air door, and the edge of preceding air door is sealed with preceding air door 7 Cooperation, the air duct 2 in air-cooler air inlet side (backwards to the directions Ku Men) offer rear air door, the rear air door edge and rear air door 8 sealing cooperations, the air-cooler 3 (do not mark, pacify respectively through refrigerant inlet pipe 9, refrigerant outlet pipe 10, disengaging shut-off valve respectively In refrigerant inlet pipe 9, refrigerant outlet pipe 10) it is connect with the entrance sleeve of reducing pressure by regulating flow element and refrigeration compressor.
Wherein, the preceding air door 7 and rear air door 8 can be driven by motor, realize that fitting wind path wall sliding opens and closes.
Wherein, the size of the air-cooler is determined according to the library size, refrigerating capacity, duct dimension, front and back air door size according to It is determined according to the size of air-cooler.
When cold storage refrigerating system is run, heat source air door 1 is closed, and preceding air door 7 and rear air door 8 are opened, and cold air is in wind Fan blows down, and by air-cooler heat exchanger tube surface cooling after-blow in cold, the heat exchange pipe surface frosting of air-cooler stops refrigeration System, heat source air door 1 are opened, and preceding air door 7 and rear air door 8 are closed, and under the blowing of fan, the hot-air of external environment is through supercooling Wind turbine heat exchange pipe surface, melts frost layer, fan blows out the air of heat absorption through air door, water accumulating disc of the defrosting water through cold wind motor spindle (not shown) is released with discharge tube, heat source air door 1 is closed later, and preceding air door 7 and rear air door 8 are opened, and cold cooling is continued as.
The above is only a preferred embodiment of the present invention, it is noted that for the common skill of the art For art personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications Also it should be regarded as protection scope of the present invention.
