This project is intended to create a program to select are way for heat pump drying machine and select pair are heat with heat pump dryer pair. Without dryer has started are two thermal size is 1.5 kW and 3.0 kW, respectively. Follow the drying 60 percent percent to bypass the local wind speed, 1.6, 2.5, dried, and 2.9 meters per second. Each wind speed to test at a temperature of 50, 55 and 60 degrees Celsius, respectively. The driver is version wiowoe was sticking to the design of the control system criteria can select are heat for drying machine. and saves the original controls. By using a PID Controller controlThe results showed that programs designed to control the behavior of the drying heat pump system. And can select are the thermal behavior of the drying system pumps the hot control. By the program can control the heat pump dryer pair, until the last remaining humidity average of 13.68 14.11% dry – standard. Electrical power is used, the maximum wind speed trials, 1.6 meters per second. 15.16. kW electrical power with low wind speed trials 2.9 meters per second. Temperature of 55 degrees Celsius equals 11.86 kW nominal pull humidity, the heat pump system of the specification 0.8 – 1.09 kg of water per kilowatt hour. Heat pump dryer pair with coefficients average 5.24 thana reliefs – 8.92.
