Domestic air heating

Is domestic air heating reliable? If you meet these three points, you can use it with confidence.

With the large-scale implementation of coal-to-electricity conversion in northern China, air-source heat pump heating has been recognized and quickly accepted by the majority of users. In winter, the temperature in northern China is low, and many areas began to centralize heating in October.

As the main fuel for central air heating in northern China, a large amount of carbon dioxide will be generated after combustion.

Due to the large number of pollutants produced, the frequent occurrence of smog disasters in recent years has made people realize that the traditional coal heating method in northern China must be eliminated.

Local governments are actively promoting coal-to-electricity replacement so that energy-saving, environmentally friendly, safe, and comfortable, zero-emission air source heat pump heating replaces traditional boilers for heating with coal.

Users don’t have to worry about using the air energy heat pump for heating at night, they can sleep comfortably until dawn, saving the trouble of adding coal to the coal-fired boiler at night.

The traditional coal-fired transformation projects in northern China are in full swing, and the cold and humid southern users feel itchy. Is it really reliable and easy to use air for home heating?

In the air heating system, the entire heating system is usually divided into three parts: the most part, the indoor terminal part, and the system control part. The key to the design of the air source heat pump heating system lies in the heat load calculation, the reasonable configuration of the unit, the selection of the type of terminal heating equipment, and the reasonable layout of the control system.

1. Heat load calculation

First, the calculation of the heat load should be carried out according to the engineering drawings and the requirements of the residents. Generally, the heat load area index method is used to estimate the heating load in winter. Thermal loads include all loads brought about by building structure thermal insulation, human body heat dissipation, building floor height, heating conditions of home appliances, and fresh air heat through doors and windows.

2. Heat pump equipment selection

According to the climate conditions of the project area, the actual installation location, the distribution of indoor pipelines, the distance of unit pipelines, economic conditions, and the total heat load, considering the heating load coefficient of household air energy, and the premise of winter heating, ultra-low temperature air energy is preferred in North China and other severe cold regions. heating unit.

3. Terminal heating equipment type

There are three kinds of common terminal heating equipment: fan coil heating system, floor heating system, and radiator heating system; among them, the floor heating system is recognized as the most comfortable way of home heating. warm feet” theory.

The temperature of hot water required for floor heating is generally around 40°C. When the temperature of the hot water generated by the air energy heat pump is around 40°C, the efficiency is high.

The use of 45°C feed water and 40°C return water temperature can meet the requirements of the indoor temperature of the floor heating system at 18~20°C, the ground at 28°C±2°C, and the spacing between the floor heating pipes at 150mm-250mm. The pipe length of each loop connected to the same temperature control center should be kept equal as far as possible, but should not exceed 100m.

Therefore, looking at the above three points, you can know whether the installed household air energy heating is reliable. In an environment where traditional energy sources are continuously exhausted, air energy heating has become a major development trend. At present, the total installed capacity of air energy heat pumps in China has exceeded 10 million units. It is one of the main equipment in the heating market in China and the preferred equipment for the “coal-to-electricity” project in northern China.

Compared with traditional boilers, air energy heat pumps do not use coal, oil, natural gas, and other fuels. When working, there will be no open flames, and no toxic and harmful gases will be emitted.

Therefore, heating using air energy heat pumps is not only environmentally friendly, but also eliminates accidents such as fire, explosion, and poisoning. The power consumption of the air energy heat pump is low, only 25% of the ordinary electric heater.

Therefore, if you want to install a reliable household air energy heating system, you must pay attention to considering the above three aspects, so that the air energy heating after installation is reliable, truly saving money and environmental protection!
