Working Principle of Air Electric Heater

In the air conditioning process, heating air has two situations: The first is to heat the air before it is treated by water, generally used in low temperature conditions in winter, usually called primary heating or preheating. Its purpose is to increase the enthalpy of fresh air and reduce humidity 2113, enhance the humidification capacity of outdoor air in the waste water chamber, so as to increase the percentage of fresh air and meet hygiene requirements. The heater used is called a preheater, which is located at the air outlet end of the fresh air chamber 5261. The second is to heat the air after it is treated by water, usually called secondary heating or reheating. Its purpose is mainly to compensate for the heat deficiency in the workshop. The heater used is called a reheater 4102, generally installed after the spray chamber baffle. Although both the preheater and the reheater are used to heat air, their functions are not exactly the same. They cannot be confused or substituted, 1653 otherwise the air state in the workshop will change.
