Household thermoelectric cold and warm air conditioning system

Abstract

The invention relates to a room thermoelectric cold heat air conditioning system, which is formed by one or several electric heat pump groups, fan coil tube or ground heat coil tube, outdoor heat absorber, cooling tower, low-height water tank, water pump, electric control valve, and connecting tubes, wherein the middle of electric heat pump groups is high-efficiency low-energy consumption thermoelectric elements as semi-conductor refrigerating chips, whose two sides are plate energy conductive water tanks, that serially and parallel connected, via tube, fan coil tube or ground heat coil tube, electric control valve, cooling tower or outdoor heat absorber, low-height water tank, heat storage water tank, and water pump, to form cycle loop. The invention has high efficiency, low cost and non pollution.

Description

Technical field: [0001] The invention relates to a cooling and heating device, in particular to a household thermoelectric heating and cooling air-conditioning system. Background technique: [0002] At present, refrigeration and air-conditioning technology has been widely used in industry, commerce, civil and daily life, and has become an indispensable and important technology in modern society. In refrigeration and air conditioning technology, the vapor compression refrigeration method is the most common application, such as household air conditioners, the refrigeration system uses Freon as the refrigerant, and the refrigeration equipment includes compressors, condensers, evaporators, and expansion valves. and other auxiliary equipment. However, there are some problems that cannot be ignored in the air-conditioning products of this cooling method: [0003] First of all, it cannot meet the needs of environmental protection: protecting the earth and the environment is the c...

Problems solved by technology

The second is noise pollution. Due to the existence of rotating parts such as compressors, noise pollution is inevitable. Especially when the per capita housing area of ​​my country's urban population is not large and the housing conditions are not perfect, this kind of pollution is more direct and more serious. Prominent, directly affecting people's quality of life

Compressors, condensers, evaporators, heat-absorbing coils, and expansion valves have high material requirements, and the manufacturing process is also quite complicated. Correspondingly, the detection methods are also very strict. These all determine the large investment and production cost of compressor air conditioners. higher

At the same time, the control technology is extremely complicated, especially for household air-conditioning systems, it is difficult to achieve precise control, which affects the further improvement of the overall performance of air-conditioning products

[0005] In order to solve the above problems of Freon air-conditioning products, many people of insight and manufacturers organize their own technical research, but due to the constraints of various factors, a substitute that is both technically and economically reasonable has not been found so far, or the efficiency is too low. Energy consumption high, or the cost is too high

For example, lithium bromide central air-conditioning units use oil, gas, coal, etc. as fuel, and the waste gas produced pollutes the atmosphere. For example, such products are no longer used in cities with high environmental protection requirements such as Hong Kong and Singapore; second, the investment is large, and the investment is The investment of single low-fluorine air-conditioning products is about two times. Third, the operating cost is high. The refrigeration coefficient of lithium bromide is only about 1.3, which is not enough for low-fluorine R 22 Half of the refrigerant, that is, its operating cost is more than twice that of low-fluorine air conditioners. It can be seen that the lithium bromide air conditioner system is not an ideal product
