NEW DEFROSTING SYSTEM FOR RESIDENTIAL HEAT PUMPS.

Author(s) : MUROZONO K., WAKABAYASHI H., HORI M.

Summary

THE HEAT PUMP IS COMPOSED OF A MAIN REFRIGERANT CIRCUIT WITH COMPRESSOR SWITCH BY INVERTER, A FOUR-TRACK GATE, AN INNER HEAT EXCHANGER, AN ELECTROMOTIVE PRESSURE-REDUCER MOVED BY A STEP BY STEP ENGINE, AN OUTDOOR EXCHANGE SYSTEM, AND A BY-PASS PATHWAY CONNECTING UPSTREAM DOWNSTREAM COMPRESSOR EXTREMITIES BY USING A TWO-TRACK GATE. ANALYSIS OF EXPERIMENTS SHOW THAT WITH THIS NEW DEFROSTING SYSTEM THE HEATING CAPACITY IS ALWAYS ONE-SIXTH OF STANDARD LEVEL, WITH GOOD COMPRESSOR RELIABILITY EVEN IN DEFROSTING CONDITIONS.
