Abstract

Direct expension earth coupled heat pump or refrigerent loop system has simplest technology with a lower installation cost and increased performance in efficiency without need of circulating pump for transfer media is required. The present system consists with 20 feet long and 11/8 inch diameters thermoeveporator outer and inner pipes (3 & 4), each thermo evaporator pipe consists with refrigerant and metering device or expansion device which is sealed in each pipe and together with indestructible copper and silver brazing. Each outer and inner pipe is made with refrigeration grade copper tube. Each thermo evaporator pipe is inserted in pre drilled vertical holes grouted and connected in parallel with insulated copper tubing. Check valve ball is closed into the heating mode loop system and open in cooling mode system. Liquid refrigerant is evaporate between outer and inner pipe into the heating mode loop system and outer pipe is contact with earth into the heating mode loop system.
