Ground-coupled heat pump and electric thermal storage water tank combination system

Abstract

The invention relates to a ground-coupled heat pump and electric thermal storage water tank combination system and belongs to the technical field of heating ventilation air conditioning in the new energy field. The system comprises a water source heat pump unit, a tail end side circulating water pump, a ground side circulating water pump, an electric thermal storage water tank and two temperature control electric regulation valves, wherein a hot water inlet of a water source heat pump unit condenser is connected with an outlet of the tail end side circulating water pump, a cold water outlet of the water source heat pump unit condenser is connected with a water supply pipeline of the ground side, and a cold water inlet of the water source heat pump unit condenser is connected with an outlet of the ground side circulating water pump; an inlet of the ground side circulating water pump is connected with an outlet of the electric thermal storage water tank, the inlet of the ground side circulating water pump is also connected with the second electric regulation valve, an inlet of the electric thermal storage water tank is connected with a water return pipeline of the ground side through the first electric regulation valve, and an inlet of the first electric regulation valve is also connected with the second electric regulation valve. By the adoption of the system, peak load shaving can be achieved, operation expenses can be reduced, and electric capacity increase is reduced.

Description

technical field [0001] The invention belongs to the technical field of heating, ventilating and air conditioning in the field of new energy, and in particular relates to a combined system of a buried pipe ground source heat pump and an electric heat storage tank. Background technique [0002] With the country's emphasis on energy conservation and emission reduction, new energy sources have been well promoted, and ground source heat pump systems, as a new energy source, are gradually being recognized. In the ground source heat pump system, the buried pipe system has been well applied. At present, because the main principle of the buried pipe system is to obtain cold from the soil in summer and heat from the soil in winter, the energy imbalance rate in the two seasons is generally not allowed to exceed 15%. The underground pipe system is rarely used in the heating system, because the problem of energy imbalance has not been well solved, and the operating cost cannot be effect...
