Device for synchronously supply heat to water source heat pump from geothermal energy and air energy

Abstract

The invention provides a device for synchronously supply heat to a water source heat pump from the geothermal energy and the air energy, belonging to the technical field of water source heat pumps. The device comprises a geothermal energy heat accumulation device which is formed by installing U-shaped inserting pipes into a deep well; and the device also comprises an air energy heat exchange device, a water source heat pump, a heat supply water tank, a geothermal energy heat accumulation device and an air energy heat exchange device which are used for supplying heat to the water source heat pump synchronously. The device for synchronously supply heat to the water source heat pump from the geothermal energy and the air energy is simple and reasonable in structure and convenient to install and use; the water source heat pump is supplied with heat in a mode that the geothermal energy and the air energy are supplied synchronously, so that the device ensures that under any environment, two groups of heat energy are supplied synchronously for the operation of the water source heat pump unit, and an optimal working performance can be obtained constantly; the heat is supplied synchronously from the geothermal energy circulation and the air energy forced convective circulation; the quantity of geothermal energy heat supply is reduced, so that the number of the inserting pipes in the deep well is reduced, then the heat stability of the geothermal energy resource is relatively reliable, and the investment cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of water source heat pumps, in particular to a device for synchronously heating ground energy and air energy to the water source heat pump. Background technique [0002] The application of ground energy resources in the HVAC industry has been very popular. Ground energy: it is a renewable energy, energy-saving and environmentally friendly, and it is an energy-saving application technology that is mainly promoted in the energy industry; however, the government has made clear regulations on groundwater exploitation. Thick layers are prone to water and soil erosion, so groundwater mining is not allowed; although groundwater mining is allowed in the northern central plains, it must be recharged, and the cost of recharge is far greater than the cost of mining, which restricts the utilization and development of ground energy. Now there is a method of using deep well intubation to avoid mining and recharging. Due t...

Problems solved by technology

However, as the temperature drops in winter, the COP of the air source heat pump decreases, and the energy consumption increases; especially in rainy winter weather, the evaporation temperature is too low, and the evaporator fins condense frost, which cannot absorb heat energy in the air, and the system cannot operate
