Description

Technical Field

[0001] The utility model relates to a refrigeration device for cold storage and air conditioning equipment, which is mainly suitable for a refrigeration device with a forced air cooling outdoor unit. Background Art

[0002] In daily maintenance, we found that many small and medium-sized air conditioners did not cool or had significantly reduced cooling effects during the dog days of summer. This was because the outdoor unit's air-cooled condenser had too much dust, which resulted in poor heat dissipation. Too much dust caused poor heat dissipation, which resulted in the actual energy consumption of the air conditioner being much higher than the designed energy consumption. Many compressors were damaged because the condenser had poor heat dissipation, which caused the compressor to run under high temperature and high pressure for a long time. Most air conditioner outdoor units are installed on the exterior walls of buildings, and manual dust removal poses a challenge to the safety of maintenance personnel. Summary of the invention

[0003] The utility model aims to solve the many problems caused by the automatic dust removal of the condenser and the poor heat dissipation due to too much dust in the outdoor unit of the forced air cooling refrigeration device, such as low refrigeration efficiency, high failure rate, the actual energy consumption of the refrigeration device after a period of cumulative operation is much higher than the designed energy consumption, reducing the number of high-altitude operations of air conditioner maintenance personnel, and extending the service life of the refrigeration device.

[0004] To this end, the utility model provides a refrigeration device with two-way air supply and automatic dust removal by water washing. Its composition structure is as follows: it comprises a casing (1), a water reservoir (3) installed on the top of the casing (1), the water reservoir (3) is connected to the condensation water pipe (9) of the indoor evaporator on the top, and is connected to the electromagnetic valve (7) and the spray water pipe (6) on the bottom, and an electronic water level meter (5) is installed in the water reservoir (3). The fan (2), the fin tube cluster (4) and the spray water pipe (6) are installed in the casing (1), the spray water pipe (6) is on the top of the fin tube cluster (4), the fan (2) is on the side of the fin tube cluster (4), and a waste water pipe (10) is installed at the bottom of the casing (1). And a capillary tube (11) and a compressor (8).

[0005] Through the study of existing air conditioners and refrigeration devices, it is found that the dust accumulated on the fin clusters of the outdoor unit condenser is mostly catkins, poplar hair, dandelion-like flocs and fine dust. The reason for the formation of floc dust is that the flocs cannot pass through the gaps of the fins and are blocked and deposited on the fins.

[0006] In order to solve the problem of floc deposition on the flap tube cluster, the present invention provides a two-way air supply device, that is, after the refrigeration and air conditioning equipment is shut down, the digital control circuit of the refrigeration and air conditioning equipment automatically jumps to the outdoor fan reversal mode, and the fan (2) is reversed for one minute to blow off the flocs on the flaps by reverse air supply. Reverse air supply is a simple and effective method to solve the problem of floc deposition.

[0007] In order to solve the problem of fine dust deposition on the fin tube cluster, the present invention provides a fin tube washing device, which uses the waste condensed water generated by the indoor evaporator to wash the condenser of the outdoor unit. The condensed water of the indoor evaporator is recovered into the water reservoir (3) on the top of the casing (1) through the condensed water pipe (9). After the water accumulates to a predetermined water level, the electronic water level meter (5) controls the solenoid valve (7) through the air conditioner digital control circuit to open after the fan reverse air supply is completed, and supplies water to the spray water pipe (6) installed on the top of the fin tube cluster (4), so as to clean the fin tube cluster (4). The water flows from the upper part of the fin tube cluster (4) to the bottom and is discharged through the waste water pipe (10) on the casing (1).

[0008] Only by keeping the condenser clean can the air conditioner operate under the designed energy consumption. Otherwise, the dirtier the condenser, the greater the energy consumption of the air conditioner. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the structure of the utility model invention. DETAILED DESCRIPTION

[0010] The accompanying drawings are an embodiment of the invention of the utility model, comprising a housing (1), a water reservoir (3) installed on the top of the housing (1), a condensation water pipe (9) of an indoor evaporator connected to the water reservoir (3) above, and a solenoid valve (7) and a spray water pipe (6) connected to the bottom, and an electronic water level meter (5) is installed in the water reservoir (3). A fan (2) and a fin tube cluster (4) and a spray water pipe (6), a compressor (8), and a capillary tube (11) are installed in the housing. The spray water pipe (6) is at the top of the fin tube cluster (4). A waste water pipe (10) is installed at the bottom of the housing (1). The air conditioner is turned on to enter the cooling mode. When the room temperature reaches the set temperature, the air conditioner is shut down, and the fan (2) reverses under the control of the air conditioner digital control circuit to reversely supply air to the fin tube cluster (4) for one minute to blow off the flocculent sediment outside the fin tube cluster. A reverse air supply dust removal is completed.

[0011] When the air conditioner is in cooling mode, condensed water formed by the indoor evaporator is continuously collected into the water reservoir (3) through the condensed water pipe (9). When the water level reaches a predetermined height, the electronic water level meter (5) controls the solenoid valve (7) through the air conditioner digital control circuit to open and supply water to the spray water pipe (6) after the fan reverses the air supply, so as to clean the flap tube cluster (4). After the water in the water reservoir (3) has flowed out, the electronic water level meter (5) controls the solenoid valve (7) through the air conditioner digital control circuit to close, and the air conditioner enters the standby mode, waiting for the next cooling operation. Thus, one water washing and dust removal is completed.

[0012] It can be seen from the above that the present invention has the characteristics of two-way air supply and automatic dust removal by water washing, and solves many problems caused by the automatic dust removal problem of the outdoor unit condenser of the air conditioner and the poor heat dissipation caused by too much dust, such as poor refrigeration effect, high failure rate, actual energy consumption is much higher than the designed energy consumption, reducing the number of high-altitude operations of air conditioner maintenance personnel, and extending the service life of the refrigeration device.
