Description

[0001] technical field

[0002] The invention relates to the field of ground source heat pump systems, in particular to an energy-saving system utilizing a heat recovery type water source heat pump unit and a control method thereof. Background technique

[0003] The existing ground source heat pump system is generally equipped with two sets of heat pump units, one is dedicated to air conditioning, and the other is dedicated to hot water. Usually, the two systems are completely independent. With some improved designs, the hot water unit While another set of heat pump unit is used for cooling, the cooling water on the ground source side is used as the cold source to prepare domestic hot water. In winter, the ground source side is used as the cold source to prepare domestic hot water. However, there are three problems in this system: one is the hot water unit Not participating in the cooling and heating work throughout the year is obviously wasteful in terms of system configura...
