- •
TEPS is a tube encircled photoelectric sensor used to monitor the degree of frosting.
- •
A novel TEPS defrosting control method was proposed and a field test was conducted.
- •
Accuracy and stability of the TEPS method under different conditions are confirmed.
- •
Advantages of the TEPS method compared to the conventional T-T method are presented.
- •
The TEPS method is a promising alternative defrosting control method for ASHP.
