Abstract
A system for preventing fogging in air conditioning systems is disclosed. The system employs a strategy whereby if fogging conditions are present, the temperature of the evaporator is stepped downwardly in increments which allow the surface of the evaporator to stabilize thereby eliminating localized cold spots.
Claims8
A method of controlling fogging in an air conditioning system of the type employing an evaporator and a pump driven by a prime mover, said pump circulating refrigerant through the evaporator, including the steps of:
- A) determining if conditions for fogging exist,
- B) in response to an affirmative determination in step A. lowering the temperature of the evaporator at a controlled rate.
Anti-fogging air conditioning system, comprising:
- an air conditioning compressor,
- an evaporator coupled to said compressor,
- means for sensing the temperature of said evaporator,
- means coupled between said sensing means and said compressor for determining if fogging conditions exist and if fogging conditions exist,
- means for lowering said temperature of said evaporator at a controlled rate.
