Benefits of technology

[0019] As stated, the heating component is positioned outside of the interior of the motorhome. It is understood that the heating component will make noise during operation, and that noise could potentially annoy occupants of the motorhome. By positioning the heating component on the outside of the motorhome, sound must travel through the coach body in order to reach the interior of the motorhome and any occupants therein. However, the coach body will have natural sound dampening characteristics, and additional sound insulation might be included inside the walls of the coach body, both of which will substantially dampen noise generated by the heating component. Therefore, positioning the heating component as such will significantly reduce the amount of heating component noise reaching the interior of the motorhome. These and other objects and advantages of the present invention will become more fully apparent from the following description taken in conjunction with the accompanying drawings.

Embodiment Construction

[0023] Reference will now be made to the drawings wherein like numerals refer to like parts throughout. FIG. 1 shows an preassembled vehicle frame 100 mounted to a preassembled chassis 102. The vehicle frame 100, mounted to the chassis 102 in the manner that will be described in greater detail below, facilitates the construction of a motorhome 104 (FIG. 3) with a greater interior ceiling height, which in this embodiment, is at least 7′-6″ in a reduced time span. The vehicle frame 100 also facilitates mounting of relatively massive items, such as generators, furnaces, storage and holding tanks, and the like low to the ground so as to provide a lower center of mass for the motorhome 104.

[0024] The vehicle frame 100 provides a strong three dimensional space frame 118 to inhibit twisting of the vehicle frame 100 under torsional forces such as would arise when the motorhome 104 drives over uneven terrain so as to lift or drop a wheel 116 with respect to the other wheels 116. The vehicle...

Abstract

A unitized heating, ventilation, and air conditioning (HVAC) system for ventilating and regulating the air temperature inside a motorhome. Air is drawn from inside the motorhome and is directed to a furnace and an air conditioning unit via a common air return. A filter is positioned within the common return. The HVAC unit is compact and adapted for placement below the living area of motorhome so as to reduce the noise inside the cabin generated by the HVAC system and to reduce the center of mass of the motorhome so equipped.

Description

RELATED APPLICATIONS [0001] This application is a continuation of U.S. application Ser. No. 09 / 971,779 entitled “Motorhome HVAC System” filed Oct. 4, 2001 which is a continuation-in-part of U.S. application Ser. No. 09 / 728,946 entitled “Motorhome With Increased Interior Height” filed Dec. 1, 2000. This application also claims the benefit of U.S. Provisional Application No. 60 / 318,136 (attorney docket ALFALE.045PR) filed Sep. 7, 2001 entitled “Motorhome HVAC System.”BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates to the field of vehicle heating, venting, and air conditioning (HVAC) systems and, in particular, to an HVAC system adapted for motorhomes in which the HVAC system is substantially positioned outside the living portion of the motorhome and employs a common air return system. [0004] 2. Description of the Related Art [0005] Motorhomes have become an increasingly popular and common means of recreation. Motorhomes are self-propelled vehi...
