Novel heat pump system for heating ventilation air conditioning engineering

Abstract

The invention discloses a novel heat pump system for heating ventilation air conditioning engineering, and relates to the technical field of heat pump systems. The novel heat pump system comprises a water storage tank. An electric heating boiler is fixedly connected to the end, away from the water storage tank, of a heating through pipe, and the output end of the electric heating boiler is fixedlyconnected with a hot water inlet pipe. A cold water inlet pipe is connected with a temperature-controlled water collector through a first control valve, and the output end of a heating chamber communicates with a temperature-controlled water separator through a water outlet main valve pipe. The output end of the temperature-controlled water separator is separately and fixedly connected with a thermal cycle return pipe and a cold cycle return pipe, and a third control valve and a fourth control valve are correspondingly arranged at positions, close to the temperature-controlled water separator, of the thermal cycle return pipe and the cold cycle return pipe. The novel heat pump system for the heating ventilation air conditioning engineering achieves the purposes of the improvement of the cyclic utilization rate of a heating water source, the reduction of the heating heat loss rate, the improvement of a heating effect, the timely detection of fault conditions of system internal circulation and the improvement of safety of the heat pump system.

Description

technical field

[0001] The invention relates to the technical field of heat pump systems, in particular to a novel heat pump system for heating and ventilation engineering. Background technique

[0002] Water source heat pump unit: a heat pump type integrated water-air or water-water air-conditioning device that uses water as the heat source and can perform refrigeration and heating cycles. It uses water as the heat source for heating and water as the heat source for cooling. heat source.

[0003] The working principle of winter heating: the water pump takes the groundwater from the water extraction well and sends it to the water source heat pump unit. The groundwater with low-grade heat energy is absorbed by the unit, and then sent back to the ground through the recharge well, where it exchanges heat with the earth again to increase the heat energy and reuse it. .

[0004] The liquid refrigerant in the water source heat pump unit, after absorbing the low-grade heat energy...
