Temperature Drop Across Evaporator Coil
The temperature drop across the evaporator coil is a crucial parameter in refrigeration systems, significantly impacting system efficiency and performance. It represents the difference between the refrigerant’s temperature at the evaporator inlet and outlet.
Factors Influencing Temperature Drop, Temperature drop across the evaporator coil should be
The temperature drop across the evaporator coil is influenced by several factors:
- Evaporator coil design: The geometry, surface area, and material of the coil affect the heat transfer rate and, consequently, the temperature drop.
- Refrigerant flow rate: A higher refrigerant flow rate increases the heat transfer rate and reduces the temperature drop.
- Air flow rate: A higher air flow rate increases the convective heat transfer from the air to the refrigerant, leading to a larger temperature drop.
Equation for Temperature Drop
The temperature drop across the evaporator coil can be calculated using the following equation:
ΔTevap= (h cA)/(m rC p,r)
- ΔT evap: Temperature drop across the evaporator coil (°C)
- h c: Convective heat transfer coefficient (W/m 2K)
- A: Evaporator coil surface area (m 2)
- m r: Refrigerant mass flow rate (kg/s)
- C p,r: Refrigerant specific heat capacity (J/kgK)
