The work is devoted to control systems for hybrid heat pumps using the heat of return network water and outside air, designed to operate in district heating systems based on CHPP. The aim of the research is to develop control systems for heat pump operating on qualitative, quantitative and quanti-tative-qualitative heat schedules. The set goal is achieved by introducing two controlled heat exchang-ers: one of "refrigerant-water" type, installed after the evaporator and "refrigerant-air" type, installed after the gas cooler. The most important results are the hydraulic scheme of the heat pump, the control system scheme of gas superheater installed after the evaporator and gas supercooler installed after the gas cooler. The significance of the obtained results consists in obtaining a technical solution, which ensures the operation of the heat pump at different heating schedules. Equations of heat pump apparat-uses have been obtained, in which the influence of flow rate and temperature of the working body on the heat pump operating mode is emphasized. The obtained heat balance equations allowed obtaining structures of automatic control systems for heat exchange apparatuses, compressors and controlling valves of the hybrid heat pump. The developed scheme of the heat pump air duct allowed using a mini-mum of heat of return network water in the heat pump. It is established that the scheme of this automatic control system should include a functional converter linking the temperature of the outside air and the coordinates of the working body state at the outlet of the gas subcooler. |
