Electronic control panel for a room air conditioner

A compressor apparatus includes a compressor housing having a mating surface with at least one electrical terminal associated therewith. An electrical connector assembly includes a hermetically sealed body having an axial face configured to lie adjacent to the mating surface of the compressor housing. A first electrical connector is molded substantially within the body. The first electrical connector is for connection with a source of electrical power. The first electrical connector is in communication with the axial face of the body. The first electrical connector is configured for connection to the at least one compressor terminal. A second electrical connector is substantially molded within the body. The second electrical connector is in communication with the axial face of the body. A thermal cutoff device is electrically and removably connected to the second electrical connector. At least one closed-loop seal substantially seals the at least one compressor terminal, the first electrical connector, the second electrical connector and the thermal cutoff device from an ambient environment.

Sealed electrical connector assembly

An air conditioning unit comprising a refrigeration assembly, an air handling assembly, and a control assembly. The refrigeration assembly includes a generally rectangular base pan having upturned edges and a floor having a raised section, the base pan having a condenser, an evaporator, and a compressor mounted to an upper surface thereof. The air handling assembly includes a bulkhead having adjacent side wall portions, a scroll, a motor having an output shaft, a motor mount bracket for engaging the base pan of the refrigeration assembly, a fan, and a blower engaging the output shaft of the motor, a fan shroud and struts for mounting the shroud to the bulkhead and an air plenum assembly. The control assembly includes a control housing and a control panel.

Modular room air conditioner

An electronic controller for a room air conditioner includes a memory for storing operational parameters, a thermistor for measuring ambient temperature, and a microprocessor capable of calculating the difference between the ambient temperature and the temperature set point, and capable of controlling the speed of the fan and fan motor based on the difference between the ambient temperature and the temperature set point. The controller includes an electronic system clock, an electronic control panel with a display, the ability to store in memory a start time for normal operation of the room air conditioner and a stop time for ending normal operation of the room air conditioner, and a timer mode activation device. The controller is also able to detect and store the cumulative length of time that the fan blower has operated, to compare the stored length of time to a predetermined length of time, to indicate when the stored length of time is equal to or greater than the predetermined length of time, and to reset the stored length of time to zero.
