Does the Micro HPS have a variable-speed control?
A – No. In the Micro HPS such a control would provide no benefit. The Masterflux compressor is a variable-speed compressor and we do manufacture variable-speed controls for use in many other systems that we build. However, but we do not use them on the Micro HPS. To build the most energy efficient system possible, you would perfectly match the capacity of the compressor to the heat load. The function of a variable-speed compressor control is to change the speed of the compressor to try to accomplish this “on-the-fly”. In other words, if you put a bunch of warm food into your refrigerator, you significantly (but temporarily) increase the heat load on the compressor. If the system has a traditional evaporator and a properly designed variable-speed control it would respond by temporarily speeding up the compressor to compensate. Once the food had cooled, the compressor would slow back down again to try to match the lower heat load. This approach is better than simply ignoring the change i
