Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification heat pumps, and in particular to a sound insulation and noise reduction structure for a three-in-one dehumidification heat pump. Background Art

[0002] A three-in-one dehumidification heat pump is a heat pump that integrates three functions: pool water heating, pool room air dehumidification, and indoor air conditioning. The fan of the equipment draws warm and humid air from the pool room, and the air flows through the evaporator coil, transferring the recovered heat energy to the cold liquid refrigerant while cooling and dehumidifying. This energy exchange causes the air temperature to drop below the dew point, forming condensation on the evaporator coil. The formed moisture flows into the liquid receiving pan of the equipment and is discharged through the drain pipe, and the humid air is transformed into dry cold air. The three-in-one dehumidification heat pump tends to generate loud noise when working, and in order to avoid the impact of noise on the external environment, a sound insulation and noise reduction structure is usually required.

[0003] Upon checking, the disclosure (announcement) number: CN218645757U discloses a sound insulation and noise reduction structure for a three-in-one dehumidification heat pump, which includes a frame, a support seat is fixedly installed at the bottom of the frame, an air inlet is opened at one end of the top of the frame, and an air outlet is opened at the other end of the top of the frame. A sound-absorbing plate body is fixedly installed on the frame, a noise reduction pad is arranged between the sound-absorbing plate body and the frame, and the frame is sleeved on the outside of the unit. The beneficial effect of the utility model is that the utility model can effectively reduce noise by sleeved a frame on the outside of the unit, and a sound-absorbing plate body is fixedly installed on the frame, a noise reduction pad is arranged between the sound-absorbing plate body and the frame, and a sound-absorbing layer and a noise reduction layer are arranged inside the sound-absorbing plate body, thereby playing the role of noise reduction and noise reduction.

[0004] A silencer plate is arranged on the outside of the unit to reduce noise to a certain extent. However, an air inlet and an air outlet are arranged on the unit. When the unit is working, the airflow directly enters along the air inlet or is discharged directly from the air outlet. The collision of the airflow with the components of the air inlet and the air outlet will also generate a large noise. For this reason, we propose a sound insulation and noise reduction structure for a three-in-one dehumidification heat pump to solve the above problem. Utility Model Content

[0032] Working principle:

[0033] When the utility model is used, by arranging a silencer plate 11 on the inner wall of the dehumidification heat pump housing 1, the interior of the dehumidification heat pump housing 1 can be soundproofed and noise reduced. The silencer plate 11 is a common prior art. When the dehumidification heat pump housing 1 is working, the airflow enters along the air inlet box 2 and is discharged along the air outlet box 3. When the airflow enters along the air inlet box 2, the airflow is restricted by a plurality of airflow silencers 4 in the air inlet box 2, so that the airflow generates a large number of airflow vortices at the position of the air inlet box 2, greatly reducing the flow rate of the airflow, and reducing the noise generated when the airflow passes through the air inlet box 2. At the same time, the noise generated when the airflow passes through the silencer cotton 10 on the inner side of the airflow silencer 4 is reduced. The noise is absorbed to prevent the noise from being emitted to the external environment; when the airflow is discharged along the air outlet box 3, the airflow is restricted by a number of airflow silencers 4 in the air outlet box 3, the airflow velocity is reduced, and the noise generated when the airflow passes through the air outlet box 3 is reduced, and the dehumidification heat pump box body 1 is subjected to all-round sound insulation and noise reduction treatment; the positioning frame 6 is detachably installed on the top of the air inlet box 2 or the air outlet box 3 through the elastic clip 7 and the locking card strip 8. The positioning frame 6 can restrict the airflow silencer 4 inside the air inlet box 2 or the air outlet box 3 to ensure the stability of the airflow silencer 4 during operation, and at the same time facilitate the disassembly and assembly of the airflow silencer 4.
