Patent number: 7051544Abstract: 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.Type: GrantFiled: July 9, 2004Date of Patent: May 30, 2006Assignee: Carrier CorporationInventors: Andreas Hille, Robert C.

Patent number: 6983619Abstract: A module is provided for attachment to the roof of a bus and includes all of the necessary components for conditioning the return air from the passenger compartment and delivering conditioned air thereto. Each module may include an evaporator section, a condenser section and a power section including a compressor and an inverter. The condenser section includes a condenser coil and a transverse fan with its axes disposed horizontally so as to draw air through a fresh air intake opening, through the coil and out a condenser discharge opening. The drain pan is shaped so as to form an air guiding wall around the fan, and a vortex wall is attached to the condenser coil support structure to separate low and high pressure sides of the fan. A rear wall and the fins of a discharge grill are angled with respect to the vertical plane so as to thereby prevent a recirculation of hot discharged air back into the air intake opening.Type: GrantFiled: May 5, 2003Date of Patent: January 10, 2006Assignee: Carrier CorporationInventors: Andreas Hille, Robert C.

Patent number: 6763668Abstract: Rather than having a frame into which, or upon which, an air conditioning system is mounted, a bus rooftop air conditioning module has a unibody which is formed partially of structural members interconnected to the tube sheets of the evaporator and condenser coils to form a structural body which supports the components of the system. In this way the coil tube sheets combine with other structural members to form the supporting body.Type: GrantFiled: May 5, 2003Date of Patent: July 20, 2004Assignee: Carrier CorporationInventors: Peter R.

Patent number: 6763670Abstract: A bus rooftop air conditioning system is made up of one or more self-contained modules having one or more evaporator sections and one or more condenser sections, with each extending transversely across the width of the bus, and with the evaporator sections fluidly communicating with both a common return air opening and a common supply air opening of the bus. The modules may be of a single unit configuration with a single condenser section and a single evaporator section or they may be of a double unit configuration having two condenser sections and two evaporator sections. The total capacity requirements are met by combining the use of single units and double unit configuration, with each of the evaporator sections communicating with a single return air opening and a single supply air opening in a bus.Type: GrantFiled: May 5, 2003Date of Patent: July 20, 2004Assignee: Carrier CorporationInventors: Peter R.

Patent number: 6763669Abstract: A module is provided for attachment to the roof of a bus and includes all of necessary components for conditioning the return air from the passenger compartment and delivering conditioned air thereto. A module can be ganged in various relationships to collectively provide the total capacity required by the bus. Each module includes an evaporator section, a condenser section and a power section including a compressor and an inverter. The evaporator sections have a return air compartment that extends a substantial distance across the roof of the bus such that a single design can meet the needs of various return air duct installations of various types of buses. Provision is made for the selectively mixing of return air with fresh air, with the mixture then being passed by the evaporator blower through the evaporator coils and into the supply air ducts.Type: GrantFiled: May 5, 2003Date of Patent: July 20, 2004Assignee: Carrier CorporationInventors: Peter R.
