Separated type solar water heater with freeze prevention and frost resisting functions

Abstract

The invention discloses a separated type solar water heater with freeze prevention and frost resisting functions, and relates to the separated type solar water heater which has a freeze protection function and a frost resisting function. The interchange and realization of the two functions are fully based on zero power consumption independent of any external electrical energy, and the two functions can be crossly used or selectively used in different districts or in different environments in the same district so as to bring great expedience for clients. The separated type solar water heater prevents freeze and does not consume power and resists the frost without an anti-freeze fluid; the system adopts a single circuit to directly replace heat transfer in a high efficiency manner, the heat efficiency is high, the system cost is low, and the cost performance is ultrahigh; the whole separated type solar water heater adopts a full mechanical structure and is safe and reliable, and the freeze prevention and frost resisting problems of a flat plate collector are thoroughly solved. The separated type solar water heater with freeze prevention and frost resisting functions is an all-weather solar water heater which is truly high in efficiency, is convenient and in a zero power consumption, and has large popularization and application values.

Description

technical field [0001] The invention relates to a split solar water heater system with antifreeze function and antifreeze function, belonging to the field of solar water heaters. Background technique [0002] With the continuous deepening of energy conservation and environmental protection, more and more people choose to use solar water heaters. The climate conditions in various regions of our country vary greatly, which requires the production of solar water heaters to meet the climate requirements of various regions. Solar water heaters can be used according to Different regions have different sunshine conditions, and adopt different configurations of collector area and water tank volume. However, another serious problem is that the temperature in each region varies greatly, and the number of days with temperatures below zero is not the same. According to the different climatic conditions in the region, it is economical, reasonable and convenient to solve the freezing of s...

Problems solved by technology

At present, the antifreeze solution of flat solar water heaters popularized in the market mainly uses antifreeze, and the system adopts double-circuit natural circulation indirect heat exchange, which has high cost and low thermal efficiency, and there are safety hazards; the antifreeze solution mainly adopts circulation pump, Relying on electric energy for forced heat exchange, the hot water in the water tank is circulated to the collector at the set temperature to prevent freezing. The system architecture is complex, and relyi
