Function of heating

Heating refers to the facilities used to keep out the cold in winter in northern China and countries and regions with low annual temperature. Broadly speaking, it refers to the products and methods that let everyone get the heating demand. It is a product that heats the heat medium and then heats the air through the heat source to form heat exchange, thus improving the ambient temperature. The common heating facility in the north is water heating scheme. In fact, the earliest design demand mainly comes from the freezing of water pipes in winter in areas where the temperature will reach below 0℃, and the countermeasures arising from this phenomenon.

In short, heating is a supporting service or incidental function of urban residents' water supply demand, and heating in a narrow sense refers to central heating facilities. It transports the steam or hot water generated by the boiler to the radiator indoors or in the car body through the pipeline, radiates heat, raises the indoor temperature, and then flows back to the boiler for reheating cycle. It is stipulated that heating must use clean water to benefit people's health, heating must use clean water to benefit the environment, and heating must use clean water to benefit the image of heating enterprises.

Central heating has obvious advantages, good heating effect, high resource utilization rate and low average cost. The main disadvantage is that residents have no choice but to adjust the temperature. The heating effect of high-rise residents is relatively poor, but the charge is the same. Some residents owe money, but the heating is still used as usual, which is unfair.
