Heat exchange system adopting cold source control method to realize intelligent constant temperature and control method of heat exchange system

Abstract

The invention relates to a liquid heating technology, discloses a heat exchange system adopting a cold source control method to realize intelligent constant temperature and a control method of the heat exchange system and aims at solving the problem that the liquid temperature needed to be manually regulated of the existing beverage machines including drinking water machines. The heat exchange system adopting the cold source control method to realize intelligent constant temperature comprises a heating system, a heat exchange system and a liquid inlet pipe which sequentially passes through theheat exchange system and the heating system and is used for introducing a liquid to be heated; a hot liquid pipe and a warm liquid pipe are connected to one end, extending out of the heating system,of the liquid inlet pipe; the warm liquid pipe penetrates through the heat exchange system; heat exchange is performed on the high-temperature liquid in the water liquid pipe to become a medium temperature liquid by the heat exchange system; a temperature control sub-pipe is connected to the liquid inlet pipe; the two ends of the temperature control sub-pipe are connected to the liquid inlet pipeand pass through front section and the back section of the heat exchange system respectively; and the liquid inlet pipe is provided with an electromagnetic valve and a control system for controlling starting and closing of the electromagnetic valve. The heat exchange system has the effect of automatically regulating the liquid temperature according to different environments.

Description

technical field [0001] The invention relates to a liquid heating technology, in particular to a heat exchange system using a cold source control method to realize an intelligent constant temperature and a control method for using a cold source control method to realize an intelligent constant temperature heat exchange system. Background technique [0002] First of all, all kinds of direct drinking water equipment products on the market adopt various heating methods, which cannot really avoid the occurrence of raw water, yin and yang water, thousand boiling water, etc., and also cannot avoid the secondary pollution of drinking water caused by materials and manufacturing processes , safety and health cannot be guaranteed. [0003] Secondly, most of the water dispensers on the market are heat storage type, and most of them do not have the function of pipeline sterilization. The water dispenser has secondary pollution. The dust in the air carries a large number of microorganisms...

AI Technical Summary

Problems solved by technology

Faucets, heating tanks, water storage tanks and pipelines are prone to breed bacteria when they are in contact with air for a long time, especially in the environment where warm boiled water is used. Sampling and testing of warm boiled water in the drinking water industry is almost unqualified

If you drink this water for a long time, you may have intestinal diseases at any time, which will damage your health.

Especially the temperature of warm boiled water, as the temperature of tap water varies throughout the year, there is a large temperature difference in the outlet temperature of warm boiled water from heat exchangers with fixed heat transfer areas. The water temperature is adjusted manually by adjusting the mixing valve on the market, which cannot reach Ideal needs
