Solar photo-thermal loop heat pipe air conditioner heating system and control method thereof

Abstract

The invention provides a solar photo-thermal loop heat pipe air conditioner heating system and a control method thereof, and belongs to the technical field of solar photo-thermal loop heat pipe air conditioner systems. The hardware structure of the solar photo-thermal loop heat pipe air conditioner heating system is improved; according to the technical scheme adopted for solving the technical problems, the loop heat pipes are arranged on a heat pipe side face evaporation plate, a heat pipe top face evaporation plate and a heat pipe back face condensation net frame of the air conditioner outdoor unit, and the two ends of the heat pipes on the heat pipe top face evaporation plate are connected with the heat pipes on the heat pipe side face evaporation plate and the heat pipe back face condensation net frame respectively. Meanwhile, a direct-current variable-frequency compressor is connected with the heat pipes arranged on the heat pipe side face evaporation plate, the heat pipe top face evaporation plate and the heat pipe back face condensation net rack, and heat pipe working medium one-way valves are installed at the two ends of the heat pipes on the heat pipe back face condensation net rack respectively; a loop heat pipe liquid storage capillary evaporation pipe section is mounted on the heat pipe, connected with the direct-current variable-frequency compressor, of the heat pipe side evaporation plate; the invention is applied to air-conditioning water heaters and heating machines.

Description

technical field [0001] The invention discloses a solar photothermal loop heat pipe air conditioner heating system and a control method thereof, belonging to the technical field of solar photothermal loop heat pipe air conditioner heating. Background technique [0002] With the national and local restrictions on the use of coal-fired boilers, the use of coal-fired boilers below 20 steam tons / h has been strictly prohibited. More and more coal mine heating methods are replaced by gas boilers, solar energy, soil source heat pumps, air source heat pumps, and electric heating. [0003] Due to the large area and high floor height of buildings such as canteens and machine repair workshops in coal mine buildings, the heating load in winter is very large. Now some canteens, machine repair rooms and other buildings in coal mines have begun to use air source heat pump systems for heating in winter. Due to the single use of the air source heat pump system for heating in winter, the num...

Problems solved by technology

Due to the single use of the air source heat pump system for heating in winter, the number of air source heat pumps in the heating system is large, and the investment in the heating system is large.

And when the outdoor temperature is lower than -15°C, the COP value of the air source heat pump heating system is greatly reduced, resulting in high energy consumption and other problems
