I. Overview

The ground source heat pump system is a leading --r -conditioning technology that can achieve many advantages of the water source heat pump system, and can also save considerable operating costs. The ground source heat pump system solves the problem of groundwater recovery of the water source heat pump system to prevent the impact of groundwater resources on the use of heat pump units and the possibility of groundwater pollution. The system occupies a small space, and the installation and use of the system will not change the appearance and structure of the building. The ground source thermal pump system is flowing in the underground circulation system through the thermal media solution to achieve heat exchange with the earth. The system is a closed closed circular circulation system. He is a new technology -energy -saving technology with sust--nable development.

Second, system

1. Strong engineering concept -Most of the entire control system of tr--ning devices adopts the actual application of industrial site.

2. Technical Advanced -Control System partly applies PLC control technology that represents the technology trend of the central --r -conditioning control system today. It fully considers the scalability of the system and compatibility with other subsystems of the building.

3. Good openness -the whole set of tr--ning devices adopts transparent and open design. The tr--ner can intuitively and clearly understand the work process of the entire device. The system control part of the source code is completely open. Perform innovative and design tr--ning.

Third, function

The ground source thermal pump system is a closed circular circulation system that uses heat in underground rock soil. It flows in the closed underground buried tube through the circulating liquid to achieve heat exchange between the system and the earth.

1. In the winter heating process, the fluid absorbs heat from the ground, and then brings heat to the room through the heat pump system.

2. The system runs during summer refrigeration; the indoor heat is brought to the underground rock soil. Therefore, the ground -coupled source heat pump system m--nt--ns the advantages of the groundwater source heat pump using the ground as the advantages of the ground as a hot and cold source, and at the same time, there is no need to extract groundwater as a medium for heat transfer. Various disadvantages,

3. Destiny water: The ground source heat pump system provides family water for the family in winter and summer
