Description

Domestic economical convenient environmental protection automatic heating system

The technical field is as follows: the invention relates to a household economical, convenient and environment-friendly automatic heating system, and belongs to the field of environment-friendly household equipment

Background

At present, heating work is related to the life of thousands of households, social stability is related, and for northern cities, the heating problem is still a hot spot problem reflected by residents in winter.

The main government heating problem solving method is central heating, which is a concept derived from household heating, and as the name suggests, central heating is that people collect heating from a centralized place instead of heating for each user. The professional point is that a centralized heat source is built in a certain unit, such as a city or a small town, each household leads warm air to the home from the heat source, and the whole centralized heating system can be divided into three parts, namely, a first part is a heat source, a second part is a heat network, and a third part is a user. The heat source is a source of heating air, generally classified into geothermal heat and a boiler, the fuel of the boiler is generally coal, natural gas, nuclear fuel, garbage and the like, and the heat supply network is a center for transporting heating air from the heat source to a user's home. And plays a role of connection.

The most obvious advantage of central heating lies in the integration of resources to achieve the purposes of saving energy and improving the energy utilization rate, the energy utilization rate can reach 80% by adopting the central heating, although China is a big energy country, along with the development of industry and the rapid increase of population in recent years, the energy has already faced the situation of shortage, and people know that the formation of coal and natural gas is very long, and the central heating belongs to non-renewable resources. Once used up, reformation requires lengthy waiting. Energy conservation has been the subject of the era. The centralized heating reduces the loss caused by transporting energy to a plurality of places, and the mature technology can greatly improve the energy utilization rate. Energy conservation is achieved to a great extent.

2. The second major advantage of central heating is that it can protect environment, and can be used by all residents in a city or a certain unit with only one or several heat sources, thus changing the pattern of multiple heat sources and multiple pollution. On the other hand, the method is also beneficial to the optimal layout of urban land, and when selecting the heat source address, a place with the minimum pollution to the city can be selected, so that the improvement of urban air quality and the improvement of the living environment of people are facilitated.

3. Convenient and safe, low in price and capable of supplying warm air for 24 hours.

The central heating has many advantages, and the inherent disadvantages are inevitable, the manufacturing cost in the early stage is very high, the construction scale is large, and the construction cost of the heat network is high, which is the fatal weakness of the central heating. The large and medium-sized cities generally adopt a mode of building a thermal power plant, and on one hand, power supply channels and self-power consumption of enterprises are increased. The problem of local central heating is solved at the same time, so that two purposes are achieved. But also addresses large-scale geographic and environmental conservation and capital and fuel sourcing issues. In small towns, many obstacles are faced to solve the problem. Even if allowed by national policy, land, environmental and capital sources are difficult obstacles to surmount.

Some disadvantages with respect to central heating. Due to the progress of household appliance production technology and the popularization of pipeline natural gas in China. In the areas with better economic conditions in China. And a plurality of families adopt the technology of heating by using the gas wall-mounted boiler.

Compared with the wall-mounted boiler, the central heating system has the following characteristics:

1. the wall-mounted gas stove has the advantages that the wall-mounted gas stove is high in controllability and capable of meeting the heating requirements of multiple rooms, each room can be set to be at a comfortable temperature at will according to the requirements, and one room can be determined to be independently closed for heating according to the requirements, and large-flow constant-temperature sanitary hot water can be provided for places such as family bathing and kitchens. The defects are that the cost is high, maintenance and regular cleaning are needed, corrosion prevention is added regularly, and the cost is saved without centralized heating.

2. The latter is warmer than a gas wall-mounted stove. Because the gas hanging stove has powerful family central heating function, can satisfy the heating demand in many rooms, each room can set for comfortable temperature according to the demand at will, just want how warm just to adjust how warm promptly.

3. In terms of economy, central heating is cheaper. The central heating is mainly a heating mode using an urban heat supply network, a regional heat supply network or large-scale central heating as a heat source. In China, a central heating mode is generally adopted.

Disclosure of Invention
