Ground source heat pump energy storage central air-conditioning system

Abstract

The invention provides a ground source heat pump energy storage central air-conditioning system. The ground source heat pump energy storage central air-conditioning system comprises a U-shaped pipe, connecting pipes, horizontal pipes, heat preservation mechanisms, supporting mechanisms, and fixing mechanisms. The connecting pipes are connected to the two ends of the U-shaped pipe in a sleeving mode. The horizontal pipes are connected to the ends, back to the U-shaped pipe, of the connecting pipes in a sleeving mode. The heat preservation mechanisms are connected with the U-shaped pipe, the connecting pipes and the horizontal pipes in a sleeving mode. The supporting mechanisms are fixedly connected with the heat preservation mechanisms. The fixing mechanisms comprise first shells, second shells, first rings, second rings, and connecting rods. The second rings are connected with the connecting pipes in a sleeving mode. One ends of the connecting rods are fixedly connected with the secondrings. The other ends of the connecting rods are fixedly connected with the second rings. The ground source heat pump energy storage central air-conditioning system supports heat preservation cottonat the connecting position between the U-shaped pipe and the horizontal pipes, and therefore the service life of the heat preservation cotton is prolonged.

Description

technical field [0001] The invention relates to the technical field of a ground source heat pump energy storage central air conditioning system, in particular to a ground source heat pump energy storage central air conditioning system. Background technique [0002] The ground source heat pump central air-conditioning system is a new energy utilization technology that uses shallow ground energy for heating and cooling. It is a kind of heat pump. A heat pump is a device that uses the principle of Carnot cycle and reverse Carnot cycle to transfer cooling and heat. Ground source heat pumps usually refer to the ability to transfer heat or cold in the underground soil to where it is needed. Heat pumps are usually used for air conditioning cooling or heating. The ground source heat pump also makes use of the huge heat storage and cold storage capacity of the underground soil. The ground source transfers heat from the underground soil to the building in winter, and then transfers t...

Problems solved by technology

[0003] However, the soil layer on the ground is divided into exothermic layer, normal temperature layer and inner thermal layer. During installation, U-shaped pipes need to be buried in the outer thermal layer and the normal temperature layer. The temperature of the outer thermal layer will change with the outside temperature. The normal temperature layer is at a constant temperature all the year round, so when the water flows through the exothermic layer after being heated and cooled by the normal temperature layer, the temperature of the water changes again due to the different temperature of the outer thermolayer, so that when the user uses the system, The effect of preheating and precooling cannot be achieved; thus, the water pipe needs to be insulated, but the connection between the U-shaped pipe and the horizontal pipe is not easy to support with insulation cotton, which makes it very easy for the water pipe to squeeze the insulation cotton The insulation cotton here is easily damaged
