WebThe heat transfer can be enhanced by increasing the mass flow rate of the system. For example : Suppose refrigerant is circulating through evaporator and condenser at specific mass flow rate X. Now, the requirement for cooling is increased. If we put the refrigerator at max, The mass flow rate of the refrigerant will get increase. WebNov 4, 2024 · When latent heat is absorbed or released, it produces instability in the atmosphere, potentially producing severe weather. The change in latent heat alters the temperature of objects as they come into contact with warmer or cooler air. Both latent and sensible heat cause air to move, producing wind and vertical motion of air masses.
