Heat supply device taking solar energy for heating mainly

Abstract

The invention discloses a heat supply device taking solar energy for heating mainly. The heat supply device is characterized in that a heat utilization device is connected with a solar heater througha first heat exchange, the water outlet end of the first heat exchanger is connected with a temperature sensor, an electric heating heat exchanger is connected with the temperature sensor, the electric heating heat exchanger and a branch circuit are connected in parallel, the water outlet end of the electric heating heat exchanger and the water outlet end of the branch circuit communicate with anelectricity utilization device through a loop, a water inlet is further formed in the electricity utilization device, a water outlet is formed in the first heat exchanger, and the temperature sensor is also connected with a temperature control switch. The heat supply device has the advantages that the solar energy is taken primarily, electric heating is taken secondarily, so that the energy is saved, and the environment is not polluted.

Description

technical field [0001] The invention relates to a heating device, especially suitable for rural self-built houses without central heating. Background technique [0002] At present, small boilers are generally used for heating in rural self-built houses in the north, which greatly pollutes the environment, while traditional coal heating devices are more dangerous, and carbon monoxide poisoning incidents often occur; electric heating can overcome the above shortcomings, but the cost is relatively high. high. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a heating method based on solar energy and supplemented by electric heating. Multiple sets of solar heating devices can be set up in idle places such as roofs and yards of houses, and can be connected with pipelines through pipelines. The heating device is connected to solve the heating problem; the specific technical solution is...
