AI Technical Summary
Existing heat pumps operate with low efficiency and instability at extremely low ambient temperatures, making it difficult to effectively utilize the latent heat of water vapor in the air. This results in large heat exchange equipment size, high energy consumption, and difficulty in achieving stable heating in extremely cold weather.
The system employs a multi-reverse Carnot cycle cross-heat exchange medium system. By connecting the main circulation system with the first auxiliary circulation system, a non-refrigerant side loop is formed. The system is connected to an external heat exchange device using a heat exchange circulation pump to achieve multiple heating and cooling cycles, thereby reducing the temperature difference between the condenser and the evaporator and improving the temperature exchange efficiency between the heat transfer medium and the outside air.
To achieve efficient operation of heat pumps in extremely low temperature environments, improve the energy efficiency ratio, reduce the size of heat exchange equipment, lower investment costs, and enable stable heating and cooling in extremely cold weather, adapting to the heat pump demand at extremely low temperatures.
