Description

technical field [0001] The invention belongs to the technical field of building energy saving, and relates to a solar photovoltaic loop heat pipe capillary copper tube heating system with condensers connected in parallel. Background technique [0002] At present, the solar heating system is mostly a single hot water heating system or an ordinary floor radiant heating system. For the existing solar water heating system, most of the condensers adopt direct or indirect heat exchange in the form of spiral coils. The length of the spiral coil is long, and the resistance when the refrigerant flows through is relatively large, which is easy to cause water temperature stratification, and the thermal efficiency of the indirect heat exchange method is low. At the same time, the structure of the condenser will cause problems such as loose structure and occupying space in the water tank. Existing solar radiant floor heating systems require high water temperature, require indirect heat ...
