A vehicle heating, air conditioning and ventilation system comprises a housing (10) within which an evaporator (12) and heater (14) are arranged generally in a diverging V shape enclosing a mixing space (M) between. All forced air passes through the evaporator (12) first, after which it is can go straight through to the mixing space (M), or be diverted down under the heater (14) to flow through the heater (14) and into the mixing space (M), or some combination of the two. The combination of cold and hot flows into the mixing space (M) is determined by a solid dividing wall (30), which partially blocks the evaporator (12) and heater (14) from one another, and a pair of separate rolling film belts (32, 34), one between the evaporator (12) and the dividing wall upstream side (36) and the other located between the dividing wall downstream side (38) and the heater (14). Each belt (32, 34) has respective windows (48, 56) and solid areas (50, 58) which can be shifted to selectively block or unblock flow into the mixing space (M). The two belts (32, 34) in conjunction with the solid dividing wall (30), prevent any air that has passed through the evaporator (12) from by passing the heater (14). In addition, the individuality of the two belts (32, 34) allows a wide combination of temperatures and air flows to be achieved, and also allows the respective windows (48, 56) to be staggered to promote mixing.

[ What is claimed is:] [1.]1. A vehicle heating, ventilation and air conditioning system with a housing that has an evaporator through which substantially all of a forced air stream is directed and a heater located downstream of said evaporator through which air can be selectively directed after having passed through the evaporator, said evaporator and heater having outer faces directed away from one another and inner faces generally opposed to one another and defining an air mixing space between their respective inner faces, characterized by,an air flow diversion passage extending from the lower edge of said heater inner face around to the outer face of said heater, so that at least a portion of the forced air that has passed through said evaporator can be diverted around to flow completely through said heater and into said air mixing space,a solid dividing wall located between said opposed heater and evaporator inner faces with an upstream side facing said evaporator inner face and a downstream side facing said heater inner face, said dividing wall also being sealed against the lower edge of said heater inner face so as to block a portion of said opposed evaporator and heater inner faces from one another and so as to direct any air passing through the evaporator and impinging on the upstream side into said diversion passage,a rolling evaporator belt located between said evaporator inner face and the upstream side of said dividing wall and extending from said dividing wall across the remaining portion of said evaporator inner face, said evaporator belt having at least one window therein to allow said evaporator inner face to be blocked or unblocked to any desired degree, in conjunction with said dividing wall, and,a rolling heater belt separate from said evaporator belt, located between said heater inner face and said dividing wall downstream side, and extending from said dividing wall across the remaining portion of said heater inner face, said heater belt having a least one window therein to allow said heater face to be blocked or unblocked to an any desired degree, in conjunction with said dividing wall,whereby forced air that has passed through said evaporator flows either directly into said mixing space, or along said solid dividing wall upstream side and into said diversion passage, but is prevented by said solid dividing wall from leaking directly in front of said heater inner face without passing through said heater.
