The inlet temperature of the circulating water is higher than the ambient air temperature in spring, autumn, and winter – how can it then serve a cooling purpose?
Thermal equilibrium is like water flowing downhill.
It’s possible for it to be higher than the ambient temperature, but it has a higher heat capacity. If you use an air cooler, what large a heat exchange area will be required!
It is used to cool high-temperature media, not the environment; what does it matter if it’s hotter than the air temperature?
The inlet temperature of the circulating water is higher than the outdoor atmospheric temperature during spring, autumn, and winter, but it is low enough compared to the hot-side temperature of the heat exchanger to enable cooling.
It is a cycle: the cooling water absorbs heat, which is then transferred through the cooling tower where it evaporates. The evaporation process involves water molecules carrying away the heat from the water, thereby achieving the purpose of cooling the equipment. Keyword “calories”. (The relationship between heat and temperature should be noted)
It is related to the ambient temperature, but not absolutely; this heat is primarily generated through the latent heat of evaporation, rather than through natural cooling due to the ambient temperature.
That makes sense, right? It’s sufficient as long as the temperature of the cooling medium is lower than that on the process side. A low ambient temperature is more favorable for cooling.
