Abstract
A module for a bus rooftop air conditioner is self contained in that it has all the necessary components including a compressor, if desired, which when supplied with electrical power, can provide conditioned air to the passenger compartment of a bus. In addition, an electrically powered heater is provided in the air flowstream such that heated air can also be supplied to the passenger compartment when desired. Multiple units provide for incremental capacity requirements to be met as well as limp home capabilities.
Claims9
A vehicle air conditioning system comprising:
- an electrical generator driven by an engine;
- a self-contained air conditioner module comprising:
- a condenser;
- an expansion device;
- an evaporator,
- a condenser blower driven by an AC electric motor;
- an evaporator blower driven by an AC electric motor,
- an electric heater located in air flow relation to said evaporator and said evaporator blower, and
- a power controller for receiving AC electrical power from said generator and providing AC electrical power to each of said condenser blower motor, said evaporator blower motor, and said electric heater;
- wherein said power controller comprises:
- a rectifier to convert said AC power to DC power;
- and
- an inverter for inverting said DC power to inverter output AC power. said inverter output AC power being supplied to said condenser blower motor, said evaporator blower motor, and said electric heater.
