Temptress DIY Kit - Specifications
BTU Output
Given the flexibility that the system provides, you can adjust the air conditioner to meet your unique needs by varying both the compressor and evaporator fan speed. Below is a table that is representative of how the system will perform given three different scenarios. Please note that in order to test the system, we had to direct the four evaporator ports into a single plenum with a 4" hole on the other side. It was the only way to have a consistent way to measure the airflow and BTU. But, it did increase the return pressure. Thus, your mileage may vary. Note: The RV version is about 10% less efficient than the water cooled version.
