The working principle of sewage source heat pump noise elimination

Release Time：2021-07-21

Sewage source heat pump, as the name suggests, is mainly an innovative technology that uses urban sewage as a cold and heat source for extracting and storing energy, and uses the material circulation change of the refrigerant inside the heat pump unit system to consume a small amount of electricity to achieve the cooling effect.
The main working principle of the sewage source heat pump is to use the sewage source heat pump compressor system to consume a small amount of electricity, extract the low heat stored in the water in the winter, provide heat for the user, extract the indoor heat in the summer, release it into the water, reduce the room temperature, achieve the cooling effect, water source heat pump energy source flow is the use of heat pump unit energy (electricity) to absorb all the heat energy (that is, electricity to absorb the heat) together to the high temperature heat source, the energy consumption is the medium compressed to high temperature and high pressure state, so as to achieve the absorption of low temperature heat source in the role of heat energy.
The interests of environmental protection, heat saving coal, gas, oil and other boiler room system, no combustion process, avoid smoke pollution of cooling tower, avoid noise and mold pollution of cooling tower, do not produce waste residue, waste water, waste gas and smoke, environmental benefits are significant.
In winter, the temperature of the sewage body is higher than the ambient air temperature, the evaporation temperature of the heat pump cycle is increased, and the energy efficiency is also improved. In summer, the water temperature of the water source heat pump is lower than the ambient air temperature, the condensation temperature decreases, and the cooling effect is better than that of the air cooling type and the cooling tower type, which improves the unit efficiency.
Because the operation, management and maintenance of water source heat pump is more convenient, with the dual function of cooling and heating, the heat dissipation of the unit does not need a cooling tower, therefore, more and more applications. However, the noise of the unit is easy to have a certain impact on the surrounding environment, which requires us to take measures to control.
From the noise source and noise characteristics of water source heat pump, as well as the noise control examples of the unit, and the technical point of view of noise control and control, in order to reduce the noise pollution of water source heat pump, one of the more common methods in the market is to adopt a fully enclosed sound insulation muffler on the unit, which can better solve the problems of ventilation, heat dissipation, air intake and exhaust of the unit and ensure the normal operation of the heat pump.
Especially when the exhaust residual pressure of the heat pump is low or the specific residual pressure is not known, there can be a specific calculation basis in the design of the air inlet and exhaust system of the sound insulation muffler device. The water source heat pump itself has the characteristics of energy saving and environmental protection, and the control of its noise highlights its characteristics. It is believed that the application of water source heat pump equipment in the market will be more and more widely.
