Problems solved by technology

They are all fixed devices, which are bulky, costly, and difficult to expand. During use, issues such as antifreeze and damage need to be considered
In actual use, the use of solar energy and the supporting heat pump unit are basically in an independent state, which is not conducive to energy saving

Embodiment

[0040] Embodiment: In autumn and winter, due to more wind, the indoor temperature is higher than the outdoor under the same sunlight, for example: the indoor temperature is 8°C, and the outdoor temperature is -2°C. Using this heating system, it is judged by testing that the temperature difference between the inlet and outlet of the collection device is less than 10°C, and the outlet temperature is greater than 3°C, then the heat pump is turned on, the collection device extracts the wind from the evaporator for solar heating, and the warm air from the outlet enters the evaporator to convert the refrigerant gas change. At the same time, the condenser introduces indoor air, and in the heat pump, the refrigerant releases heat, and the air flowing through the condenser is warmed up and returned to the room.

[0041] Direct heating mode: When the sunlight is sufficient and the heating system is used, and the temperature difference between the inlet and outlet air of the collection d...

Abstract

The invention provides a solar heat collecting device. The solar heat collecting device comprises a plurality of heat collecting rods which are arranged side by side and formed by heat pressing soft plastics, the heat collecting rods are internally provided with air flow channel cavities, the sunny sides of the heat collecting rods are provided with transparent plastic layers, the night sides of the heat collecting rods are provided with black coatings, inlet air of each heat collecting rod is connected to a total air inlet, outlet air of each heat collecting rod is connected to a total air outlet, and the total air inlet is connected with a ventilator. The invention further provides a solar heating system. The solar heating system combines the solar heat collecting device and an air heatpump to supply warm air to the indoor environment. The invention further provides a using method of the solar heating system. According to the method, a working mode that air is sucked from the indoorenvironment to be heated, and the warm air is directly returned to the indoor environment is provided, moreover, a working mode that low-temperature warm air heated by the collecting device is used for gasifying a refrigerant, and then the refrigerant releases heat to indoor circulating air with the relatively high temperature is provided, the heat collecting rods are made of plastic films, the heat collecting rods are inflated to be unfolded during use, and are vaccumized to be folded during un-use, so that storage and transportation are facilitated, and the heating system is low in cost, light in weight, easy to assemble or disassemble, and free of freezing risk.

Description

technical field [0001] The invention relates to a solar utilization technology, more specifically to a solar heat collection device, a solar heating system and a using method thereof. [0002] technical background [0003] The use of existing solar energy is mainly through solar water heaters or solar collectors to realize the utilization of solar energy. In solar water heaters, the water density difference of water or the power provided by water pumps are used to circulate the water in the water tank to the panels of the collectors, and the sunlight It can reach the inside of the panel, the water absorbs solar energy, the temperature rises, and this cycle increases the temperature to meet the needs of heating or hot water, and some use heat pipes. There are heat pipes in the panel, and refrigerants are used in the heat pipes. Medium, under the effect of density difference, the liquid refrigerant circulates into the copper tube in the panel, vaporizes, the gas rises to the he...
