Problems solved by technology

[0003] Some parallel solar heat pump water heaters currently installed and used are a simple combination of solar units and air energy heat pump units, which are controlled separately. They are not integrated water heater products of solar energy units and air energy heat pump units, which is not conducive to popularization and use.
Therefore, the integrated control system has become a technical bottleneck for the promotion and application of parallel solar heat pump water heaters

Description

technical field [0001] The invention relates to a control system, in particular to a control system of a parallel solar heat pump water heater. Background technique [0002] Solar heat pump effectively combines solar water heater and air energy heat pump water heater. It is a more efficient energy-saving hot water equipment that can extract heat from solar energy and air energy at the same time. It avoids the influence of time and weather on single solar water heaters and heat pump water heaters. insufficient. This new type of heating technology is both environmentally friendly and energy-saving. It has obvious social benefits and long-term economic benefits. It is of great significance today when energy and environmental problems are becoming more and more prominent. [0003] Some parallel solar heat pump water heaters currently installed and used are a simple combination of solar units and air energy heat pump units, which are controlled separately. They are not integrate...
