Features and advantages of sewage source heat pump central air conditioning

In the northern region of China, winter heating is mainly obtained by burning fossil fuels such as coal, oil and natural gas. Heating and environmental protection have become a pair of intractable conflicts. Municipal sewage is an indispensable heat pump cold and heat source in the cold northern region. Its temperature is relatively stable throughout the year, higher than the ambient air temperature in winter and lower than the ambient air temperature in summer. This temperature characteristic makes the sewage source heat pump operate more efficiently than the traditional air conditioning system, and the energy saving and operation cost saving effect is remarkable.　Raw sewage source heat pump unit takes raw sewage as the heat source, collects low-grade heat energy from sewage in winter, and with the help of heat pump system, supplies the obtained energy to indoor heating by consuming part of electric energy; and takes out the indoor heat and releases it into the water in summer, in order to achieve the purpose of air-conditioning in summer. It has the following characteristics:

Energy efficient

The sewage source heat pump system has the advantages of stable heat output, high COP value, good heat transfer effect, compact unit structure, etc. It is an effective way to realize sewage resource utilization. Sewage source heat pump phase coal-fired boilers environmentally friendly, the emission of pollutants than air-source heat pumps to reduce more than 40%, more than 70% less than electric heating. It saves energy, saving more than 2/3 of electricity than electric boiler heating, saving more than 1/2 of fuel than coal-fired boilers. Because the temperature of the heat source of the sewage source heat pump is more stable throughout the year, its cooling and heating coefficient is about 40% higher than that of the traditional air-source heat pump, and its running cost is only 30%~55% of the ordinary central air conditioning.

Green

The system does not require boilers, cooling towers and other equipment. There is no pollution from coal, oil and natural gas combustion emissions, no outdoor unit, no uncomfortable heat conduction effect, and the noise is much lower than traditional air conditioning. In winter heating, the use of 10,000 tons of sewage to heat the building for four months, can reduce CO2 emissions of 5040 tons.

Long life

Low maintenance costs of the system host equipment designed to last up to 25 years, sewage resistance machine and sewage heat exchanger life of up to 20 years or more, the system does not set up an outdoor unit, not set up cooling towers, equipment maintenance is simple, low-cost, normal use of the conditions of normal conditions under normal conditions only need to be maintained for each cooling and heating season, without coal, slag, the machine room can be done online monitoring, unattended. The machine room can do on-line monitoring, unmanned.

Multi-purpose

Small footprint system multi-purpose, a system can replace the original boiler plus air conditioning two sets of devices. It can realize three functions of heating, cooling and domestic hot water. The machine room covers an area of only 1/3 of the coal-fired boiler and 1/2 of the gas-fired unit.

Operation stability

Safety and reliability of the sewage temperature is relatively stable in all seasons, and its fluctuation range is much smaller than the fluctuation of the outdoor temperature, which makes the heat pump unit operate reliably and stably. Sewage source heat pump system uses electricity to drive the heat pump, absorbing sewage heat (or discharging heat to the sewage), without the need for combustion equipment, so there is no explosion, combustion and other hidden dangers.

Widely used

At home and abroad, there are many successful cases of sewage source heat pump system to determine its irreplaceable industry position, Reynolds & Nephew according to the different habits of people around the world, the formation of the composition of the complex raw sewage status quo, the use of indirect heat transfer principle, a systematic solution to the obstacles to the utilization of raw sewage, the more direct access to the form of heat pump unit in the form of investment risk, system stability, as well as maintenance cycle and cost. The system stability and maintenance cycle and cost, has an incomparable advantage.
