Operation of air conditioning with heating and hot water installation - involves circulating cold water instead of hot using heat exchanger and regulator valves

摘要

The installation comprises a boiler (1), flow and return pipes (2, 3) linking up radiators. A heat exchanger (10) is fitted by connecting pipes (13, 19) between flow and return pipes and a pump (9) is connected to a return link (19). Motorised valves (5, 6) are fitted to the flow and return, and additional valves (7, 8) to the link pipes (13, 19). Thus circulating water can be switched from hot to cold depending upon inside and outside temperature and humidity. USE/ADVANTAGE - Hot water domestic heating system in which extreme temp. fluctuations are eliminated.
