1. Horizontal ground source heat pump
It is exchanged with the soil by cold and heat exchange through a closed heat exchange system buried horizontally below 2 to 4 M. This type of system is suitable for buildings with small cooling and heating areas, such as villas and small single-family buildings. The initial investment and construction difficulty of the system is relatively small, but the floor space is large.

2. Vertical ground source heat pump
Through the vertical drilling, the closed heat exchange system is buried in the 50-400M deep rock and soil and the soil for cold and heat exchange. This kind of system is suitable for buildings with large heating and heating area, and there are certain open spaces around, such as villas and office buildings. The initial investment of the system is relatively high, and the construction difficulty is relatively large, but the floor space is small.

3. Surface water source heat pump
The ground source heat pump unit exchanges heat and cold with rivers, lakes, seawater, etc. through a closed heat exchange system arranged at the bottom of the water. This system is suitable for small and medium-sized cooling heating areas, buildings near the water. It utilizes the stable temperature and significant heat dissipation of the pool water or the lake underwater, and does not require drilling and trenching, and the initial investment is minimal. But there is a need for deeper, larger rivers or waters around the building.

4. Groundwater source heat pump
The ground source heat pump unit exchanges heat and cold with the deep groundwater pumped by the water pump through the closed loop system inside the unit through the heat exchanger. Groundwater is drained or injected into the groundwater layer by a pressurized pump. This system is suitable for large single buildings and small building communities with large construction area and limited open space.
Ground source heat pump application
The application mode of ground source heat pump can be divided into two categories: household and commercial, and can be divided into centralized system, distributed system and hybrid system.
Home system
Users use their own heat pump, ground source and waterway or duct delivery system for hot and cold supply, mostly for small residential, villa and other household air conditioners.
Centralized system
The heat pump is arranged in the machine room, and the cold heat is concentrated to the rooms through the air duct or water distribution system.
Decentralized system
The central water pump is used to send water to each user as a source of cold and heat by means of a water loop. The user uses his own heat pump unit to adjust the air. Generally used in office buildings, schools, commercial buildings, etc., this system can fully reflect the cold heat used by users in electricity consumption, easy to measure, and is suitable for the current independent heat metering requirements.
Hybrid system
The ground source is used in conjunction with a cooling tower or a heating boiler as a system of cooling and heat sources. The mixing system is very similar to the dispersion system except that the cooling source system adds a cooling tower or boiler.

PVC resists corrosion and chemicals, exhibits high strength, and weighs less than fittings made from metal. PVC can be connected to other materials such as steel, copper, or cast iron using transition fittings. Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries.
