Description
[introduction]
The water temperature and the outdoor temperature is low, the electric flow regulating valve opening increases, the heat exchanger heat increase, so that the two network of water temperature. Such as the two network of water temperature and outdoor temperature, electric flow regulating valve opening decreases, enters the heat exchanger heat decreases, and the two water temperature decrease. Circulating pump for variable frequency control, frequency conversion is realized by the change of temperature control. A water pump is also variable frequency control, frequency conversion is realized by two secondary return water pressure sensor to control. Because the water loop adopts frequency balance valve and supply pump, to realize the constant pressure replenishment functions. Controller programmable acquisition each point temperature and the outdoor temperature are optimized, at the same time controller with remote communication interface.
[function]
The water temperature and the outdoor temperature is low, the electric flow regulating valve opening increases, the heat exchanger heat increase, so that the two network of water temperature. If the power supply device two net for added to make the system has the power failure protection, since the function call. Fill the tank liquid level automatic control device, so that the water tank in the low liquid level alarm and water pump to stop working. When the liquid level in normal time, water pump to normal work. Due to the above control, automatic control of heating.
