The programmable controller and touch screen are used to carry out integrated control of cooling tower motor and cooling water circulating water pump, with functions such as parameter setting, running state display, running data record query, equipment failure alarm, etc.The cooling water pump does frequency conversion control according to the load change, and the cooling tower fan does frequency conversion or start-stop control according to the cooling water circulation temperature (including pressure sensor and temperature sensor). The system is highly intelligent, which can make the cooling system run more reasonable and energy saving.
