The invention discloses a ventilation system for providing heating achieved through adopting industrial power cooling system waste heat assisted by an underground heat source and a control method. Thesystem comprises a heat exchange system and a dynamic control system, wherein a power cooling water circulation system, a ground source heat energy system, a preheating system and a ventilation system body are connected to the heat exchange system; and the dynamic control system detects the temperature of each branch in the system through a temperature control point, and controls the flow of eachbranch in system through an solenoid valve. According to the ventilation system, through the above structure, the state of each branch is controlled and adjusted, and aiming to the special environment that a ground source heat pump system cannot independently complete ventilation heating due to too low temperature of outdoor air in the northeast region of China, the set of composite ventilation heating system is formed by the mode that the waste heat of a mechanical cooling water circulation system in an industrial production unit is efficiently used as a main part, the underground heat source system is used as supplement, and the waste heat compensation is assisted.
Description
technical field [0001] The invention belongs to the field of energy saving and environmental protection, and specifically relates to a fresh air system and a control method for heating by using waste heat of an industrial power cooling system supplemented by underground heat sources. Background technique [0002] During the operation of industrial power equipment, the heat generated by the power equipment will be taken away by the cooling system and released into the atmosphere by the air cooling system. In the industrial use environment, the energy consumption of engines and air compressors is the main energy consumption of an industrial unit, and the efficiency is relatively low (20-40%), and a large amount (60-80%) of energy consumption is dissipated as heat energy, while With the wear and tear of the equipment, the useful mechanical efficiency will continue to decrease, and the heat loss will be higher. This part of the energy is lost in the form of cooling tower cooling...
