Abstract
The double controlled central heat supply system has one first electrically controlled valve in the primary water return pipeline and one by-pass electrically controlled valve between the water feeding pipeline and water returning pipeline in the secondary side. The first electrically controlled valve controls the temperature of the water return in the primary water return pipeline to stabilize the water return temperature in a lowest value, increase the temperature difference between the water supply and water return in the primary side at most and reduce the flow rate in the primary side. The by-pass electrically controlled valve controls the water supply temperature in the secondary side to raise the heat exchange efficiency. The present invention has the advantages of reduced heat exchange area of the heat exchanger, lowered cost and raised heat exchange efficiency.
Description
Technical field: the present invention relates to central heating system, specifically by an electrically-controlled valve being installed to improve a kind of novel central heating system of system's heat transfer efficiency respectively between, return piping at primary side return piping and secondary side.
Background technology: present existing central heating system all is to adopt high-temperature water to convert water at low temperature to user's heat supply through heat exchanger, and heat exchanger primary side discharge and primary side supply by controlling, the variation of return water temperature difference realizes the adjusting of heating load.The heat transmission equipment of existing heating system, because the discharge of secondary side is big, the secondary side supply backwater temperature difference is little, and primary side flow and secondary side flow are differed greatly, and the heat exchange efficiency of heat exchanger reduces, and coefficient of heat transfer K reduces, and the heat exchange area of required heat exchanger is also big; Because the reduction of K value, make the supply water temperature height of primary side, return water temperature is also high, and little for, backwater temperature difference, primary side discharge increases relatively, and heat supply network primary side return water temperature is discrete simultaneously, causes the primary side efficiency of transmission to reduce, the transmission of electric energy increase; And the secondary side flow heat exchanger of all flowing through, droop loss increases.
Summary of the invention: the objective of the invention is by an electrically-controlled valve is installed at the primary side return pipe, secondary side improves heat exchange efficiency between, the return pipe and connect a bypass and mix the water electrically-controlled valve and realize two controls.Primary side electrically-controlled valve control primary side return water temperature, secondary side bypass electrically-controlled valve control secondary side supply water temperature changes the heat that obtains from heat exchanger by the control to bypass flow, thus the gross energy of control secondary side heat supply.The heat that the heat exchanger primary side provides is that the demand heat by secondary side decides.Like this, by the electrically-controlled valve on the primary side water return pipeline, control primary side return water temperature is stabilized in the range of set temperature, and the primary side supply water temperature can quite adjusted arbitrarily in the scope.The primary side flow reduces, and the primary side efficiency of transmission improves greatly, and power consumption greatly reduces; The flow through flow of heat exchanger of secondary side declines to a great extent, and the coefficient of heat transfer of heat exchanger raises, and the heat exchanger area that carries out heat exchange greatly descends; And the water yield of the secondary side heat exchanger of partly flowing through, another part bypass electrically-controlled valve of flowing through, the loop pressure drop loss reduces greatly.
The advantage of the invention: by regulating the electrically-controlled valve on the primary side return piping, lock the primary side return water temperature, the increase primary side supplies, return water temperature is poor, and the primary side supply water temperature can significantly improve, and reduces the primary side flow, and conveying energy consumption reduces; By regulating secondary side bypass electrically-controlled valve, the difference in flow of secondary side and primary side is reduced, the coefficient of heat transfer of heat exchanger significantly improves, and the heat exchange area of heat exchanger can significantly reduce like this, thereby reduces the cost of heat exchanger; Owing to increased bypath system, system's drag overall descended; By primary side, the two adjustings of secondary side, greatly improved the adjusting function of whole system.

The specific embodiment:
The present invention installs an electrically-controlled valve (3) at primary side return piping (2), and the double control system of bypass electrically-controlled valve (6) is installed between secondary side confession, return piping.An electrically-controlled valve (3) is installed on heat exchanger primary side water return pipeline,, makes the primary side return water temperature constant at a minimum by regulating the electrically-controlled valve valve opening, when the primary side return water temperature raises, electrically-controlled valve (3) aperture diminishes, otherwise it is big that electrically-controlled valve (3) aperture becomes.Because primary side supplies, backwater temperature difference strengthens, the primary side flow is reduced; Regulate the bypass electrically-controlled valve (6) between the confession of heat exchanger secondary side, the backwater, make the backwater of the secondary side heat exchanger (7) of partly flowing through, the part bypass electrically-controlled valve (6) of flowing through, when the secondary side supply water temperature is not enough, electrically-controlled valve (6) aperture reduces, bypass flow reduces, the flow of heat exchanger secondary side of flowing through increases, the energy that obtains rises, mix the back with by-pass water and form water supply, the secondary side supply water temperature rises, because the secondary side bypass flow significantly reduces, secondary side and primary side difference in flow are reduced, thereby improve the heat exchange efficiency of heat exchanger.
