Background technology
The heating ventilation air-conditioning system of existing employing radiator (being commonly called as radiator), mostly is water circulating heating system.The kind of radiator is a lot, generally can be divided into by material and processing technology: cast-iron radiator, steel radiator, composite copper aluminium radiator, die casting aluminium composite heating radiator, steel combined with aluminum radiator etc..The radiating mode of all kinds of radiators is all that heat radiation is auxiliary based on room air free convection heat exchange (accounting for more than the 80% of total heat exchange amount) above.
The operational efficiency of whole system, as the end-equipment of heating ventilation air-conditioning system, is had great impact by radiator.Due to radiator itself have intrinsic performance characteristic, in relatively-stationary environment, coefficient of heat transfer is basicly stable.
For heating system, from the angle of " behavior energy saving ", when there is heating demand indoor, the heat-sinking capability of radiator is strong, heat dissipation capacity greatly more can meet application demand;But when indoor do not have heating demand, radiator to maintain antifreeze function, the heat-sinking capability of radiator is weak, heat dissipation capacity is little more energy efficient.There is obvious contradiction in both of these case, and this contradiction is difficult to solve in existing system.
For central heating system, the relatively good control of supply water temperature, but the return water temperature of each end then compares difficult control.If return water temperature can effectively be controlled well, then the operational efficiency of system and stability all can strengthen.
Summary of the invention
When radiator 1 works, inside produces thermal current upwards and constantly heats indoor air by air circulation.The direction of the air circulation of radiator 1 is the hot-air of the top → top of air channel, the inside → radiator (1) of the bottom → radiator (1) of the cold air → radiator (1) of lower section.For central heating system, the systematic parameter such as the supply water temperature of heat supply network, flow is all metastable, the fluctuation of end load is insensitive.
