Stainless Plate Heat Exchanger Unit For Heat Transfer Equipment
Commonly used control strategies
(1) The heat exchange unit has functions of climate compensation and horizontal water supply
The programmable controller is used to automatically set the temperature of the two-side water supply according to the change of outdoor temperature and the local heat load curve, and the compensation amount can be set according to the requirements. The measured value of the secondary-side water supply temperature is compared with the set value.
Through PID adjustment, the controller outputs a signal to adjust the electric valve for temperature control
(2) Automatic water replenishment
The pressure sensor installed on the secondary side return pipe measures the pressure signal, which is ompared with the set value and outputs a control command to control the start and stop of the water pump or frequency conversion Constant pressure water replenishment
