Heating: different parts have different requirements for heating modes because the unit is in a low-temperature environment such as winter or a severe cold area, and the service life and reliability of the parts and original parts are facilitated by a certain temperature such as 25 ℃. At the moment, the soil side of the ground is in a high-temperature environment, heat is absorbed from the soil through the liquid-liquid heat exchanger, and high-temperature liquid can be transferred to different space areas of the low-temperature unit through the liquid-air heat exchanger through the compressor and the expansion valve; therefore, the temperature in different space areas is improved to a certain extent, and the integral uniformity of the space temperature in different areas of the unit is realized;
considering that different heat exchange components have different heating quantity requirements and different spatial positions of the different heat exchange components, in order to take account of the temperature consistency at the tail ends of different heat exchangers, different combination modes are adopted for heat exchange, for example, one of the combination modes in fig. 4 follows the following principle: the heat exchangers can adopt a series connection mode when the distances among different parts are close and the heat exchange quantity is less; the heat exchangers are connected in parallel when the distance between different components is long and the heat exchange amount of a single component is large.
