To avoid engine idling to support cabin heating, an auxiliary coolant heater can heat engine coolant and pump it through compartment heaters or the engine cooling system. The coolant flow control system provides great flexibility in selectively distributing heated coolant for heating and engine preheating.

Automated no-idle heating and engine pre-heat using engine coolant

A heating, ventilation and air conditioning system for a vehicle is constructed from two modules, one for the engine compartment and a second for the passenger compartment. The engine compartment module has a base formed for positioning on at least two locations on a dash panel, a outside air inlet, a secondary air inlet for communication with the passenger compartment, an air outlet and defining a air transport conduit connecting the outside air inlet or the secondary air inlet with the air outlet. Downstream from the engine compartment is a passenger compartment module having a slide slot for a heater core, an inlet for communication with the air outlet from the engine compartment module, an air manifold, a panel exhaust from the air manifold, a defrost exhaust from the air manifold, a compartment door providing access to the slide in friction slot, and an air channel from the inlet to the air manifold. The heater core is positioned in the slide in slot.

Vehicle heating and air conditioning modules

Heating, ventilation and air conditioning systems for busses having air distribution at the front of the bus through a distribution system integrated with the dashboard and outlet vents shaped and oriented to provide clearing of mist and frost from vehicle windows, particularly those in and around an entry to the vehicle. A dedicated blower for an entry way door is provided.

Driver/entry ventilation system for a bus

Heating, ventilation and air conditioning systems for busses achieve improved air distribution by the use of ducts to distribute the air throughout the passenger compartment. The ducts have a varying cross sectional area so that the impedance to air flow appears constant at all points along the duct. The quantity of air distributed from each of a plurality of vents is substantially even is effectively equalized.
