| Abstract: | Aiming at the frost-cracking problem of the dry type shell-tube heat exchanger for air source heat pump water chiller-heater unit,the main influencing factors are analyzed.The key reason of shell-tube heat exchanger frost-cracking is analyzed that is too low evaporating pressure.The design of shell-tube heat exchanger is improved based on the analysis results,and the limited flow rate for protection of flow switch is verified by the test. |
