Abstract

The present invention relates to a heat pump system and a method for recycling condenser waste heat for water supply of a heat supply network. At present, energy-saving reconstruction of a heat supply network water supply link by an absorption heat pump in domestic power plants has not been paid full attention to. The heat pump system comprises a condenser unit, and is characterized in that the system also comprises a cooling tower, an absorption heat pump unit and a first temperature gauge, wherein a cooling water outlet of the condenser unit is connected with a cooling water inlet of the cooling tower through a cooling tower water supply pipeline, a cooling water outlet of the cooling tower is connected with a cooling water inlet of the condenser unit through a cooling tower water return pipeline, a heat pump waste heat water outlet of the condenser unit is connected with a waste heat water inlet of the absorption heat pump unit, a heat supply network water return pipeline is connected with a heat supply network water inlet of the absorption heat pump unit, the first temperature gauge is installed on the heat supply network water return pipeline, and a heat supply network water outlet of the absorption heat pump unit is connected with a heat supply network water supply pipeline. With adoption of the system and the method, the efficiency of energy utilization is high, and the economic benefit is good.

Description

technical field [0001] The invention relates to a heat pump system and method for recovering waste heat of a condenser for water replenishment of a heating network, is a system capable of fully utilizing the waste heat of a condenser for heating, and belongs to the technical field of waste heat utilization. Background technique [0002] Condenser steam turbine is the main model of domestic thermal power plants. With the advancement and implementation of national energy conservation and emission reduction policies, small coal-fired heating boilers have been shut down in my country's vast heating areas, and centralized heating has been implemented. It is a feasible and economical solution to transform the condenser steam turbine with a small generating capacity into a combined heat and power unit. Some power plants in my country have already carried out the transformation, and the effect is good. Absorption heat pump is a kind of equipment that can use high temperature heat so...
