Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pumps, in particular to a variable frequency air source swimming pool heat pump. Background Art

[0002] The swimming pool heat pump is a high-tech in the field of thermal energy application in the world. It is a device that uses electric energy to transfer heat from a low-temperature heat source to a high-temperature heat source. According to the reverse Carnot cycle principle, it uses very little electric energy to drive. The air heat source above minus 15 degrees in the air is transferred to the air generator through the heat-absorbing working medium, and the heat generated by the refrigerant in the air exchanger is heated and vaporized to be released to the outside. It is a heat transport device. The liquid working medium in the device first absorbs the heat in the air in the evaporator and evaporates to form steam (vaporization). The latent heat of vaporization is the recovered heat, and then it is compressed into a high-temperature and high-pressure gas by the compressor, enters the condenser and condenses into a liquid (liquefaction), and then the absorbed heat is sent to the required heated pool water. The compressor inside the existing device is fixed in the frame with bolts. When it needs to be repaired and replaced, personnel need to open the outer protective shell and enter the frame to remove bolts and other parts to complete the maintenance. Because the compressor is too heavy, it is extremely inconvenient to repair. For this reason, a variable frequency air source swimming pool heat pump is proposed. Utility Model Content

[0023] Combination Figure 1-5As shown, the utility model provides a variable frequency air source swimming pool heat pump, including a shell 1, the surface of the shell 1 is provided with strip holes 19, the strip holes 19 are used for air intake, the device needs to continuously absorb the surrounding air during operation, absorb the heat in the air and then use it to heat the cold water, an inspection door 18 is provided on one side of the shell 1, the inspection door 18 is generally in a closed state, and is only opened when the device needs maintenance, avoiding the more complicated process of disassembling the entire shell 1, a steel frame 2 is fixedly installed inside the shell 1, the steel frame 2 ensures the stability of the components inside the shell 1, and prevents damage to the parts due to external factors, a fan 3 is fixedly installed on the top of the shell 1, and the fan 3 mainly circulates air, promotes heat exchange, and heats the In order to realize the rapid heating process, the bottom of the fan 3 is fixedly connected with an evaporator 4. When the device is running, the evaporator 4 absorbs heat energy from the surrounding environment, and the refrigerant enters the evaporator 4. Since the refrigerant itself has a low boiling point, it will naturally evaporate after absorbing heat energy. At this time, the temperature of the evaporator 4 will be lower than the normal temperature of the outside world, realizing heat energy conversion. A support plate 5 is fixedly installed at the bottom of the steel frame 2. The support plate 5 carries components to avoid damage caused by direct contact with the ground. A condenser 6 is fixedly connected to the top of the support plate 5. The condenser 6 is responsible for cooling the high-pressure gas and lowering the temperature. The cold water is converted into hot water through heat exchange in the condenser 6 and discharged to the swimming pool to realize heating. A spring 7 is clamped inside the support plate 5. The spring 7 A stopper 8 is fixedly installed at one end, and guide rails 9 are fixedly installed on both sides of the stopper 8. When the part enters the inside of the support plate 5, the part is successfully stuck on the surface of the support plate 5 under the action of the spring 7 to avoid instability caused by movement. An inlay 10 is attached to the top of the support plate 5, and a fixed cover 11 is clamped on both sides of the inlay 10. Slide rails 12 are fixedly installed on both sides of the fixed cover 11.

The compressor 16 is used to compress the gaseous refrigerant and transfer the heat energy to the condenser 6 to achieve heat conversion. A buffer pad 17 is fixedly installed at the bottom end of the bottom plate 14. The bottom end of the buffer pad 17 fits with the inlay 10 to avoid damage caused by the rigidity problem of the compressor 16, and can also reduce the noise pollution generated when the compressor 16 is working. The outside of the compressor 16 is fixedly connected with an air pipe 20, one end of the air pipe 20 is fixedly connected to the condenser 6, and the air pipe 20 is responsible for transferring the refrigerant containing heat energy to the condenser 6 for conversion to achieve heating.An arc-shaped opening 21 is provided on one side of the fixing cover 11, and the arc-shaped opening 21 does not fit the compressor 16 to avoid being stuck and inconvenient to install.

[0024] The working principle and use process of the utility model are as follows: first, since the compressor 16 is fixedly connected to the base plate 14, it is only necessary to place the compressor 16 in the top clearance groove of the inlay 10.
