Description

Technical Field

[0001] This invention relates to a "freezing rain sliding plate photovoltaic thermal energy storage heat pump", which is related to current international carbon reduction measures and China's new energy and energy-saving technology fields. Technical Background As living standards continue to improve, the global demand for heating in winter and cooling in summer is constantly increasing. Taking winter heating as an example, current heating mainly relies on fossil fuels for centralized residential heating. When occupancy rates reach over 80%, the operating cost of natural gas-fired heating is equivalent to more than 70 RMB per square meter, with nearly 30% of energy consumption occurring in intermediate stages. Moreover, the proportion of energy lost in intermediate stages is even higher when occupancy rates are low in new housing developments, making centralized heating even more difficult to achieve. This results in people not being able to enjoy a high quality of life, and new housing developments experiencing sluggish sales. Traditional air-source heat pumps, despite being over a century old, still suffer from high energy consumption and even inoperability due to frosting in low-temperature, high-humidity environments, making low-cost, high-quality heating a significant technical challenge. This technology is applied to over 60% of China's land area. This region boasts subtropical, temperate, and Mediterranean climates, and its land area is more than 60% the size of China's, comparable to that of the United States and Europe. Winter temperatures range from -5 to 10°C. The atmosphere contains abundant solar energy, providing energy to the Earth's surface, and rich in atmospheric water vapor generated by ocean evaporation. However, this resource has not been effectively utilized. A revolution in replacing traditional centralized heating in this climatically suitable region could lead to a sustainable future.

It simplifies centralized heating, which involves high energy consumption and maintenance costs, into efficient, long-lasting direct heating and cooling, eliminating intermediate energy losses.

[0016] The process principle of the simple refrigeration lifting guide heating and cooling energy storage is shown in Figure 1 、 Figure 2 .

[0017] 1. Ultra-quiet absorption of low-temperature heat source, under the driving of source measurement circulating liquid pump (H01) - built-in low-temperature cold carrier medium enters the frozen rain source slide plate pipe (C05) through the four-source louver evaporator C00 cold liquid inlet header (C06) circulation, the temperature of the plate body decreases and forms a temperature difference with the environment air, forming a cold air natural downward circulation to absorb the latent heat and sensible heat (including low-humidity air energy and solar radiation heat source) of the frozen rain ice, the temperature of the built-in low-temperature cold carrier medium increases and the enthalpy increases, enters the source liquid outlet header (C07) through the source measurement circulating liquid pump (H01) to pressurize, enters the input cold heat valve group (H03) through the guide inlet 3d and the guide outlet 3c, the simple refrigeration machine (H05) source liquid inlet L1 enters the simple refrigeration machine (H05) heat exchanger LZ to release low-temperature energy, the enthalpy of the built-in cold carrier medium decreases and the temperature decreases to become a low-temperature cold carrier medium, which is driven by the pump circulation again to enter the four-source louver evaporator C00 to complete the periodic heat extraction cycle.

[0018] 2. Cold and hot carrier medium guide micro-vibration deicing, cold and hot functions and ice melting functions in summer and winter are completed by intelligent switching of the input cold heat valve group (H03) and the output cold heat valve group (H04).
