How does the APR Control help in High Percentage outside air applications?

When dealing with high percentage outside air systems, it comes down to matching the capacity of the compressor(s) to the varied entering air conditions. The APR Control’s ability to load match will keep the compressor active despite the varied entering air conditions. This load matching ability of an APR Control enhanced system will keep discharge air temperature consistent, the discharge air below desired space dew point, as well as preventing compressor abuse from rapid cycling or floodback. These are the conditions that historically have plagued DX systems in high percentage outdoor air applications.
