Problems solved by technology

[0003] The traditional heat pump unit adopts the left and right matching design of the fan cavity + compressor cavity or the top and bottom matching design. The fan blades are placed close to the unit air cavity and facing the air outlet. The fan cavity is equipped with a fan guard. The inner "extraction" blows to the front or directly above, because the fan and the fan blades in the fan chamber rotate, and the wind flows through the fan guard net and blows out of the unit directly into the human ear, the vibration noise is relatively large, which affects the user experience; and usually the inverter board The heat sink is located on the top of the air cavity, and is located in the vertical direction of the fan blades. The air volume flowing through the heat sink during the air outlet process is not sufficient, and only accounts for a small proportion of the total air volume. The heat dissipation effect is poor, and the temperature of the drive board is high. Conducive to the stability of frequency conversion unit operation

Embodiment 1

[0030] Such as Figure 1-Figure 5 As shown, this embodiment provides a heat pump unit with a multi-stage air chamber, including a unit housing, the unit housing includes a fan chamber 20 for setting a fan 22 and a heat exchanger 21, and a fan chamber for setting a compressor unit. A compressor chamber 30, the heat exchanger 21 is arranged on the side of the fan 22 away from the compressor unit, an air outlet chamber 10 is also arranged between the fan chamber 20 and the compressor chamber 30, the The air outlet cavity 10 is provided with a side air outlet 14 whose air outlet direction is perpendicular to the air outlet direction of the fan 22 .

[0031] The wind flow direction of the present invention is as follows: the fan chamber 20 is provided with an air inlet, the air inlet is arranged on the side of the fan 22 away from the compressor chamber 30, and the air inlet is correspondingly provided with The heat exchanger 21, the heat exchanger 21 is arranged on the back of th...

Embodiment 2

[0049] In an embodiment of the present invention, the first partition 23 is provided with at least two fans 22 along its longitudinal direction, and the positions corresponding to the adjacent fans 22 in the air outlet cavity 10 are horizontal. A second partition 31 is provided.

[0050] It should be noted that when at least two fans 22 are arranged on the first partition 23, the two fans 22 are distributed up and down, and the upper and lower sides of the air outlet cavity 10 can be controlled by the fans 22. cooling at the same time, without up and down disturbance; the fan 22 includes a motor, fan blades mounted on the motor, and a mount for fixing the motor on the first partition 23 .

[0051] Wherein, the surroundings of the second partition 31 are respectively connected with the side walls of the air outlet cavity 10 .

[0052] Specifically, the second baffle 31 separates the air outlet chamber 10 into an upper part and a lower part where there is no disturbance up and ...

Abstract

The invention discloses a heat pump unit with multistage air cavities. The heat pump unit comprises a unit shell. The unit shell comprises a fan cavity for arranging a fan and a heat exchanger and a compressor cavity for arranging a compressor unit, and the heat exchanger is arranged on the side, far away from the compressor unit, of the fan. An air outlet cavity is further formed between the fan cavity and the compressor cavity, and a side air outlet with the air outlet direction perpendicular to the air outlet direction of the fan is formed in the air outlet cavity. By means of the heat pump unit, the direction of an air channel can be effectively changed, vibration and noise generated when air is directly blown out of the heat pump unit from fan blades through an air guide ring and flows through the side air outlet are reduced, noise generated by rotation of the fan is effectively dissipated in the heat pump unit, the overall noise of the heat pump unit is obviously reduced compared with an existing structure, and the heat pump unit runs stably; and as the fan is arranged in the fan cavity, the shape of the side air outlet is variable, the appearance structure can be designed in a diversified manner, and more space is provided for the overall structure design of the heat pump unit.

Description

technical field [0001] The invention relates to the technical field of heat pump units, in particular to a heat pump unit with multi-stage air chambers. Background technique [0002] The air source heat pump unit is a cycle system composed of compressor, condenser, throttling device, evaporator and other devices. The refrigerant circulates in the system under the action of the compressor. It completes the process of increasing the pressure and temperature of the gaseous state in the compressor. After entering the condenser, it exchanges heat with cold water to realize the process of producing high-temperature hot water. The refrigerant is cooled and converted into a liquid state. When it runs into the evaporator, The liquid refrigerant quickly absorbs the heat of the surrounding air, the temperature of the air around the evaporator drops rapidly, the refrigerant evaporates and turns into a gaseous state, and returns to the compressor to complete a cycle of the refrigerant. ...
