Even so, In the event the secondary pumps are a hard and fast-pace variety, there will be periods exactly where the chilled h2o circulation charge is both a lot of or as well significantly less, not matching the cooling demand from customers and wasting energy.
PWM square waves make an AC signal based mostly on their frequency (the amount of on/off cycles per 2nd) and duty cycle (the width or period of just how long the sign continues to be on in the course of Each individual pulse) along with the amplitude (the peak of the heartbeat based on the DC voltage degree), as illustrated in Figures 3 and 4.
I have worked from the HVAC industry for about 10 years. I have been a contractor, a venture manager as well as a program designer. I share all my awareness and activities here and thru my on the web classes.
