North and south universal electric heating system

Abstract

The invention discloses a north and south universal electric heating system. The north and south universal electric heating system comprises a heating device, a warm air output channel, a warm air driving draught fan, a cooling protection device and a cold and warm air exchange channel; the heating device comprises a first shell and a heat making device, the heat making device is arranged in the first shell, the warm air output channel is communicated with hot air outlets of the first shell and the cooling protection device, the warm air driving draught fan is arranged in the first shell, and the cooling protection device is a second shell with a hollow inner cavity; the heating device is arranged in the hollow inner cavity of the second shell, and the cold and warm air exchange channel is used for enabling cold air in heating space to flow back and be conveyed to the heating device; and meanwhile, warm and hot air is conveyed to the heating space. The north and south universal electric heating system can be suitable for small, medium and large space heating, is particularly suitable for heating in north places, can overcome the defect that a coal heating system is adopted in north places, atmospheric pollution is generated, the heating efficiency is low, and energy consumption is large, and can improve the indoor heating comfort to a certain degree.

Description

technical field [0001] The present invention relates to a heating system, in particular to a north-south electric heating system for indoor adjustment of room temperature in the cold season of winter. Background technique [0002] In the cold winter, especially in the north, because the weather is extremely cold, it is usually necessary to heat the room. The current heating system mainly includes hot water heating system, steam heating system and hot air heating system. At present, the hot water heating system is the most used one. The main advantages of the hot water heating system are: its room temperature is relatively stable, and the sanitary conditions are good; it can be adjusted centrally The water temperature is convenient to adjust the heat dissipation according to the change of outdoor temperature; the service life of the system is long. However, the hot water heating system also has the following disadvantages: because the hot water heating system generally uses ...

Problems solved by technology

However, the hot water heating system also has the following disadvantages: because the hot water heating system generally uses boilers for centralized heating, although coal-fired heating is economically cost-effective, this heating method consumes a lot of energy and is limited in terms of resources alone. There is another important problem. While we are consuming these disposable resources, we have also caused serious pollution to the atmospheric environment and the air we breathe, especially the air pollution caused by the smog weather in recent years. It is related to the central heating of boilers in the north in winter

On the one hand, we need a warm winter, and on the other hand, we need a fresh and clean air environment for us to breathe. As far as the actual situation and technical means at this stage are concerned, this contradictory problem cannot be effectively resolved, and it can only be minimized. Pollution

[0003] The mature heating and air-conditioning units have not been widely used for heating or heating in cold winter. There are many constraints in this regard, the most important of which is that the heating and air-conditioning units cannot function normally in the severe cold weather in the north. Its heating effect, and for example, in the cold weather in the south in winter, the current refrigeration and air conditioning mechanism is turned on for heating and heating, and the indoor air feels a little uncomfortable. This uncomfortable feeling includes the indoor air The freshness seems to be gone, and whether it is cooling or heating, the indoor air is relatively dry, and human skin tissue always feels dry due to the existence of these conditions. The lack of sufficient humidity in the air also causes people to feel uncomfortable. one of the factors
