Description

Technical Field

[0001] The invention relates to the technical field of air heat source pumps, and in particular to an energy-saving and high-efficiency heat exchange type air heat source pump system. Background Art

[0002] An air heat source pump is a system that uses the heat energy in the air for heating and cooling. It absorbs heat from low-temperature air and raises the temperature, and then transfers it to the indoor or outdoor environment to achieve the purpose of heating or cooling. The heat in the air is absorbed into the refrigerant through a circulation system, and it is compressed into a high-temperature and high-pressure state. The high-temperature and high-pressure refrigerant is then transmitted to the indoor unit through a pipeline to release heat for heating or cooling. The existing air heat source pump realizes the exchange of heat with the outside air through an electronic expansion valve, a heat exchange fan fin, and a compressor. When the outside air flows to the heat exchange fan fin, the heat exchange effect is achieved. However, the conventional heat exchange fan fins are in contact with the outside air for a long time, and are easily adhered to by dirt such as dust, resulting in a decrease in heat exchange efficiency.

[0003] For example, the self-cleaning air-energy water heater main unit disclosed in the announcement number CN214038964U realizes the flushing of the filter screen outside the condenser by setting a water pump connecting pipe and a nozzle. The reduction motor drives the threaded rod to raise and lower the nozzle on the mounting plate to fully flush the entire condenser, reducing the impact of dust collection on the casing and improving practicality.

[0004] The self-cleaning air-energy water heater water tank disclosed in the announcement number CN213657129U drives the rotating rod by meshing the second gear with the first gear, so that the cam is operated to separate the scale covered on the heat-resistant soft plate. The water pump sucks the clean water and hydrochloric acid stored in different water tanks into the nozzle through the three-way pipe and sprays them out from the nozzle. The hydrochloric acid can react chemically with the scale to make it easier to separate from the heat-resistant soft plate. The clean water can have a good flushing and cleaning effect on the heat-resistant soft plate, so that the scale at the bottom of the water tank is easier and more convenient to clean.

[0005] However, the above-mentioned air heat source pump with self-cleaning function still has the following problems in actual use: usually a large area of ​​water spraying is used for cleaning and descaling, but this type of cleaning mechanism continues to work for a long time, and the medium inside the heat exchange pipe and the fan fins needs to evaporate and absorb heat. This type of cleaning mechanism affects the efficiency of evaporative heat exchange and increases the time of evaporative heat absorption. At the same time, the efficiency of evaporative heat exchange achieved only between a single heat exchange pipe and the fan fin is low, resulting in slow heat exchange speed and insufficient temperature rise, which affects the operation of the air heat source pump.

[0006] Therefore, we proposed an energy-saving and efficient heat exchange air heat source pump system to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide an energy-saving and high-efficiency heat exchange type air heat source pump system. In order to solve the problem that the existing air heat source pump usually adopts a large-area water spraying cleaning and descaling, but such cleaning mechanism works continuously for a long time, and the medium inside the heat exchange pipe and the fan wing needs to evaporate and absorb heat. Such cleaning mechanism affects the efficiency of evaporative heat exchange and increases the time of evaporative heat absorption.

The specific contents are as follows:

[0022] 1. The heat exchange water inlet pipe enters the drainage circulation pipe and heat exchange fan fins inside the main heat exchange frame and the auxiliary heat exchange frame, and the drainage fan module works, so that the external air enters the main heat exchange frame and the auxiliary heat exchange frame through the front and rear side support brackets, and is discharged through the drainage fan modules on both sides, so that the heat exchange water stored in the drainage circulation pipe and the heat exchange fan fins evaporates and absorbs heat, and finally is discharged from the heat exchange outlet pipe to complete the heat exchange work;

The energy-saving and high-efficiency heat exchange air heat source pump system according to claim 1 is characterized in that: A self-cleaning mechanism is provided above the heat pump main unit (1), and the self-cleaning mechanism includes a main self-cleaning brush rod (21), and the right end of the main self-cleaning brush rod (21) is fixedly connected to the outer end of the driving rack (20) included in the driving mechanism, and the main self-cleaning brush rod (21) slides on the outside of the supporting bracket (5) on the front and rear sides of the heat pump main unit (1), and dust is removed from the drainage circulation pipe (12) and the heat exchange fan fins (13) inside the auxiliary heat exchange frame (8) through the main self-cleaning brush rods (21) on the front and rear sides.

5. The energy-saving and high-efficiency heat exchange air heat source pump system according to claim 4 is characterized in that: The self-cleaning mechanism comprises a secondary self-cleaning brush rod (22), wherein the left end of the secondary self-cleaning brush rod (22) is fixedly connected to the left end of the main self-cleaning brush rod (21), and the secondary self-cleaning brush rod (22) is fitted and slidably connected to the drainage circulation pipe (12) and the heat exchange fan wing (13) on the front and rear sides of the secondary self-cleaning brush rod (22), and the secondary heat exchange frame (8) and the main heat exchange frame (7) are cleaned and self-cleaned respectively by the main self-cleaning brush rod (21) and the secondary self-cleaning brush rod (22) to prevent the air drainage of the heat exchange mechanism from causing the adhesion of dust.

6. The energy-saving and high-efficiency heat exchange air heat source pump system according to claim 4 is characterized in that: The self-cleaning mechanism comprises a spray supply box (23) mounted on the top surface of the heat pump main unit (1), and reciprocating threaded rods (24) are rotatably arranged on both the front and rear sides of the top of the spray supply box (23) via bearings, and one end of the symmetrically arranged reciprocating threaded rods (24) is meshedly connected via a second sprocket mechanism (25), and the other end of the front reciprocating threaded rod (24) is meshedly connected to the outer wall of the driving shaft (9) via a third sprocket mechanism (26).

7. The energy-saving and high-efficiency heat exchange air heat source pump system according to claim 6 is characterized in that: The self-cleaning mechanism comprises an atomizing sprayer (27), and the atomizing sprayer (27) is threadedly connected to the outer walls of the reciprocating threaded rods (24) on the front and rear sides, and the atomizing sprayer (27) is connected to the spray supply box (23). After the auxiliary self-cleaning brush rod (22) included in the self-cleaning mechanism descends and squeezes the spray supply box (23), the atomizing sprayer (27) can clean the drainage circulation pipe (12) and the heat exchange fan fins (13) to prevent the heat absorption efficiency of the heat exchange evaporation from being affected.
