| Abstract: | The influences of four-way reversing valve on the system performance were investigated experimentally. The suction pressure drop loss, discharge pressure drop loss, suction temperature increase loss, and mass flow leak loss were analyzed quantitatively. The research results show that total performance loss of the system is 6.04% and 7.59%, and performance loss due to suction pressure drop respectively is 5.49% and 7.31% in cooling and heating mode. The direction of system performance increase was analyzed experimentally. |
