Combined Heat It has long been established that for high quality combined heat should be applied regulation, which must be a rational combination of at least three levels of central, generic (or local) and the individual. Change heat transfer coefficient is used only when local regulation, in particular, in regulation-tion heat transfer from the convector by changing the position regulating plate. Torye some residents who have installed radiators, close them with blankets at a high temperature of outdoor air. The disadvantage of this method increases the temperature of return water, ie increases the specific (per 1 Gcal of heat transferred to) the costs of energy to drive circulators. For its excess provider penalizes the consumer. At the same time somehow gone unnoticed that the variance of energy to pump heat compared to its costs on the settlement (for the coldest time) mode is a general feature of high-quality regulation. By the way, is not clear how the supplier should do if the temperature of return water is growing in homes, in which the project set coil, ie where This growth is already built into the project. Some suppliers, in practice, with an increase in the return water temperature just lower the temperature of the line compared to the prescribed temperature schedule. Regulation by changing coolant flow rate ('quantitative') suggests at least a 'pure' form of constancy of its temperature, ie the temperature of the water line. Each user transmits so much water in their heating appliances, as he needs to create a comfortable (physically and economically) conditions.
