Description

A hot water supply device combining a ground source heat pump unit and a boiler

technical field

The utility model relates to a hot water supply device combining a ground source heat pump unit and a boiler.

Background technique

In the use of existing ground source heat pumps, the amount of waste heat recovered by some ground source heat pumps is less than the cooling capacity. For projects with a large demand for domestic hot water, the amount of waste heat recovered according to the cooling load of the air conditioner cannot meet the domestic hot water consumption. And configuring a boiler alone to heat domestic hot water wastes the waste heat recovery function of the ground source heat pump. The temperature of domestic hot water heated by ground source heat pumps is 45-55°C, and some projects require domestic hot water to be above 60°C. Relying on the ground source heat pump alone to heat domestic hot water cannot meet the temperature requirements.
