神彩v8The ground source heat pump uses earth as heat source and heat sink, and the heat exchanger of the heat pump is buried in the ground to exchange heat and cold with the ground. The water source heat pump unit or water gas heat pump unit is usually used as the host of the ground source heat pump system. According to the arrangement of underground heat exchanger, mainly divided into vertical buried tube, horizontal buried pipes and pipe hunting three. The vertical buried tube heat exchanger usually adopts the U model, and can be divided into three shallow layers according to its buried pipe depth.
神彩v8Ground source heat pump has two types of open and closed. Open system: a heat pump system that uses water for heat transfer directly. The system should be equipped with sand blocking, anti scaling, water purification and other devices. Closed system: a closed system for injecting antifreeze in a closed plastic pipe buried in the ground and exchanging energy with water or soil through a heat exchanger. Closed system is not affected by groundwater level, water quality and other factors, so it is widely used.
1, vertical buried pipe - deep soil vertical buried pipe can get the heat of the deep underground soil. The vertical tube is usually installed in the 50-150 meters underground, one or more groups of pipe and the heat pump unit is connected, antifreeze closed plastic pipe can transfer heat energy to the heat pump, then the pump into the building needed for heating and hot water.
神彩v82, the horizontal buried pipe - the earth's surface in the depths of 2 meters underground, placed plastic pipes, plastic pipes filled with antifreeze liquid, and connected with the heat pump. The horizontal buried pipe occupies a large area and a large amount of earthwork excavation, and the underground heat exchanger is affected by the climate change of the ground surface.
