Description

Technical Field

[0001] The present invention relates to the technical field of air source heat pump units, and in particular to an air source heat pump unit with high safety. Background Art

[0002] An air source heat pump is a device that uses the heat in the ambient air for cooling or heating. The air source heat pump unit consists of four main components: an evaporator, a condenser, a compressor, and an expansion valve, forming a closed system, which is filled with an appropriate amount of working fluid. The basic operating principle of the unit is based on the reverse Carnot cycle principle: the liquid working fluid first absorbs heat from the air in the evaporator and evaporates to form steam (vaporization), and the latent heat of vaporization is the recovered heat. It is then compressed into a high-temperature and high-pressure gas by the compressor, and enters the condenser to condense into a liquid (liquefaction) and send the absorbed heat to the required heated water. The liquid working fluid returns to the evaporator after the pressure is reduced and expanded by the expansion valve, absorbing heat and evaporating to complete a cycle, and so on, continuously absorbing heat from the low-temperature source and outputting it to the heated water, directly reaching the predetermined temperature; the water is circulated in the water tank and the condenser through a circulating pump, and the refrigerant is The water flowing in the coil in the condenser absorbs the heat of the coil and is heated. The minerals in the water will gradually condense on the coil due to the increase in temperature, resulting in a decrease in heat exchange capacity, and in severe cases, the coil will be corroded. The evaporator is mainly composed of fin tubes and fans. The fan can increase the air flow rate around the fin tubes, and the refrigerant absorbs the heat of the air flow in the fin tubes. During the cooling process of the fin tubes, the moisture in the external air will condense on the surface of the fin tubes.

The third solenoid valve 959 is higher than the cleaning liquid tank 92 to ensure that the oxalic acid solution entering the purification box 951 can flow out.

[0029] Working principle:

[0030] Step 1, the compressor 7, the circulating pump 5 and the fan 83 are controlled by the controller 3 to work, the compressor 7 compresses the refrigerant into high-temperature and high-pressure gas, the gas flows in the coil in the condenser 6, the filter 10 filters the refrigerant, the expansion valve 11 changes the refrigerant flow, the refrigerant absorbs heat when passing through the fin tube 82, and is converted into low-temperature and low-pressure steam, and then returns to the liquid storage tank of the compressor 7 to realize the refrigerant circulation, the circulating pump 5 draws the air-conditioning water in the water tank 4 under the action of its own suction force, and the air-conditioning water passes through the condenser 6, the second solenoid valve 958, the water wheel shell 955, the purification box 951 and the third solenoid valve 959 in sequence to return to the water tank 4, the coil in the condenser 6 heats the air-conditioning water, the impact force of the water flow drives the water wheel 957 to rotate, and then the stirring rod 956 stirs the softening resin 954, so that the softening resin 954 is fully in contact with the air-conditioning water, the softening resin 954 adsorbs the minerals in the air-conditioning water, purifies the water, and heats the air conditioner through the air-conditioning water;

[0031] The fan 83 increases the airflow around the fin tube 82, and the refrigerant absorbs the heat of the external gas, and the low-temperature gas is used for air conditioning and refrigeration;

[0032] Step 2: When the softened resin needs to be flushed, the controller 3 controls the second solenoid valve 958 and the third solenoid valve 959 to change the passage, and the water pump 93 delivers the cleaning liquid in the cleaning liquid tank 92 to the water wheel shell 955 under its own suction, so that the water wheel 957 drives the stirring rod 956 to rotate, and the softened resin 954 is broken up. After the cleaning liquid enters the purification box 951, it takes away the calcium ions and magnesium ions of the softened resin 954, flushes the softened resin 954, and allows the softened resin 954 to be reused, so as to realize the circulation treatment of the air conditioning water and prevent the coil in the condenser 6 from being wrapped by water stains;

[0033] Step 3: When it is necessary to remove the frost or ice on the surface of the fin tube 82, the controller 3 is used to operate the first solenoid valve 85, the motor 868 and the heating plate 867. The motor 868 drives the rotating shaft 862 to rotate. The two first connecting rods 864 are driven by the two gears 863 to swing downward at the same time. The angle between the first connecting rod 864 and the second connecting rod 865 gradually increases. The lifting plate 866 drives the heating plate 867 to move downward. The heating plate 867 is at the same height as the fin tube 82. The heating plate 867 radiates heat to the outside to heat the fin tube 82, so that the frost or ice on the surface melts and is discharged from the first solenoid valve 85.

[0034] When the first connecting rod 864 is swung upward by the motor 868, the lifting plate 866 drives the heating plate 867 to rise back to the initial position, thereby completing the defrosting of the fin tube 82 and preventing the fin tube 82 from failing to work.
