Description

一种低噪音空气源热泵A low noise air source heat pump 技术领域technical field
本实用新型涉及一种空气源热泵，具体是指一种低噪音空气源热泵。The utility model relates to an air source heat pump, in particular to a low noise air source heat pump.
背景技术Background technique
空气源热泵(Heat Pump)是一种利用高位能使热量从低位热源空气流向高位热源的节能装置，其工作原理就是逆卡诺原理，即先通过极少的电能消耗一小部分的机械功，将处于低温环境，如大气或地下水等工况下的低温热能进行吸收，再通过压缩机的压缩变为高温热能，最后传输至热交换器内以加热其中的水，从而制取到高温的热水，所以它的运行过程具有能耗低、效率高、速度快、安全性好、环保性强等使用优点。Air source heat pump (Heat Pump) is an energy-saving device that uses high-level energy to make heat flow from low-level heat source air to high-level heat source. Its working principle is the reverse Carnot principle. Absorb the low-temperature heat energy in a low-temperature environment, such as the atmosphere or underground water, and then compress it into high-temperature heat energy through the compressor, and finally transmit it to the heat exchanger to heat the water in it, thereby producing high-temperature heat energy Water, so its operation process has the advantages of low energy consumption, high efficiency, fast speed, good safety, and strong environmental protection.
目前，空气源热泵的结构主要是由机壳、机壳背面的蒸发器、以及机壳内的风叶、压缩机和换热器等构成，具体工作过程是：压缩机将冷媒压缩后形成高温高压的冷媒，再经过换热器将热量传递给流经该换热器内的水，通过热交换后的低温高压冷媒经过膨胀阀后变为低温低压的冷媒，并流经蒸发器而吸取环境中的热量，从而形成温度略高的低压冷媒并回到压缩机进行下一次压缩循环，在这一运行过程中，由风叶驱动而流动的空气中的热量就会通过蒸发器被吸收导入冷媒中，冷媒再导入水中即可产生热水。At present, the structure of the air source heat pump is mainly composed of the casing, the evaporator on the back of the casing, the fan blades in the casing, the compressor and the heat exchanger, etc. The specific working process is: the compressor compresses the refrigerant to form a high temperature The high-pressure refrigerant passes through the heat exchanger to transfer heat to the water flowing through the heat exchanger. The low-temperature and high-pressure refrigerant after heat exchange passes through the expansion valve and becomes a low-temperature and low-pressure refrigerant, and flows through the evaporator to absorb the environment. In this process, the heat in the air flowing driven by the fan blades will be absorbed and introduced into the refrigerant through the evaporator In the process, the refrigerant is introduced into the water to generate hot water.
然而，常规空气源热泵在工作过程中往往会存在不少噪音，通常是压缩机工作噪音、整机及管路震动噪音、风机风扇工作噪音和气流噪音，除了压缩机工作噪音外，剩下的噪音直接或间接都由风叶运转产生的，这是因为常规空气源热泵采用轴流式风叶，这种轴流式风叶为了满足空气源热泵工作时的风通量，只能采用较高转速，由此就会带来极大的部件震动和气流扰动等噪音，而轴流式风叶又是正面出风的，也更加剧了噪音的传播和扩散。However, conventional air source heat pumps often have a lot of noise during the working process, usually compressor working noise, machine and pipeline vibration noise, fan fan working noise and airflow noise, in addition to the compressor working noise, the rest The noise is directly or indirectly generated by the operation of the fan blades. This is because the conventional air source heat pumps use axial flow fan blades. The speed of rotation will cause great noise such as component vibration and airflow disturbance, and the axial-flow fan blades are frontal, which also intensifies the transmission and diffusion of noise.

Its function is to not only ensure the use advantages of the centrifugal fan 3 at low speed and high air volume, but also solve the problem that the suction of the centrifugal fan 3 will be concentrated on the evaporator 15, which further causes the problem of easy frosting in the middle of the evaporator, that is, by adding the air guide sleeve 6 with air guide holes 61, the suction air of the centrifugal fan 3 can be diffused to the entire evaporator 15 during operation, This prevents frost from forming on the evaporator.
所述的导风孔61可采用图6、图7所示的锥台状导风孔，也可采用圆锥状导风孔。The air guide hole 61 can be a frustum-shaped air guide hole as shown in FIG. 6 and FIG. 7 , or a conical air guide hole can be used.
本实用新型所选用的离心式风叶3在低转速的情况下也能满足空气源热泵工作时的风通量，由此就会直接减少风叶运转过程中所产生的部件震动和气流扰动等工作噪音，并大 幅降低噪音等级，而且侧出风也能极大减少噪音的传播和扩散。The centrifugal fan 3 selected by the utility model can also meet the air flux when the air source heat pump is working at a low speed, thus directly reducing the component vibration and air flow disturbance generated during the operation of the fan blade. The working noise is greatly reduced and the noise level is greatly reduced, and the side air outlet can also greatly reduce the transmission and diffusion of noise.
以上所述仅是本实用新型的具体实施例，本领域技术人员应该理解，任何与该实施例类似的结构设计，均应包含在本实用新型的保护范围之内。The above descriptions are only specific embodiments of the present utility model, and those skilled in the art should understand that any structural design similar to this embodiment should be included in the protection scope of the present utility model.
