The invention, Solar Attic Pressurizer is a unique and simple approach to
a residential energy problem. The first and main purpose for the
invention is to actively move air through the attic space in the most
efficient means possible. The Department of Energy through their Energy
Star program have stated that traditional active attic fans, solar and
conventional can draw air out of your living space into your attic and
out of your house. This increased the losses in energy both in cooling
and heating which not only costs more in energy but also overworks the
air conditioning equipment. This invention not only ventilates the attic
space but uses pressure to reduce or eliminates losses from the living
space to the attic that can occur with or without an active attic
1. The claim of the invention, Solar Attic Pressurizer, is that using the
balance of components as specified in the preceding descriptions a
structures attic space may obtain a positive pressure situation and
reduce or eliminate living space atmosphere to the attic space. The first
step is placing a power source in the form of a 30-55 watt solar module
on either the South or West face of the roof with acces to the attic for
the power cord through existing attic ventalation. The second step is
locating the maximum distance towards the North and East secion of the
attic within 5 feet of the eve/soffit and mounting the blower aimed at
the bottom section of the South West section of the attic. The next step
is to push the rectangular section of the manifold over the header board
and well into the soffit. At this point simply install the flexible duct
over the round section of the manifold and the inlet side of the blower.
Finally, plug in the electrical connectors between the solar module and
the blower and as long as the sun is up the attic will be gaining
pressure. This pressure forces circulation of attic air out of existing
ventilation and also creates a pressure barrier between the living space
and the attic space reducing or eliminating cooling and heating losses to
the attic space.

BACKGROUND OF INVENTION
 The invention of the, Solar Attic Pressurizer, came about as a result of the findings by Energy Star regarding conventional solar powered attic fans and active attic fans in general. The findings, www.energystar.gov/index.cfm?c=diy_attic_ventilation, state that active attic ventilation can actually increase the loads on air conditioning and thus raise electricity consumption.
 This is due to the method of traditional attic ventilation. Air is effectually vacumed out of the attic creating a negative pressure in the attic space. This negative pressure in turn vacumes the air conditioned living space air into the attic.
BRIEF SUMMARY OF THE INVENTION
 My invention, Solar Attic Pressurizer, actually draws cool shaded ambient air from the eve or soffit and blows this air into the attic space creating a positive pressure. This positive pressure not only forces the heated attic space air out of existing ridge and soffit vents but also reduces the natural losses of airconditioned pressurized air from the living space.

DETAILED DESCRIPTION OF INVENTION
 All other active attic ventilation systems, solar or otherwise, have been designed to vacume air from the attic space. The Solar Attic Pressurizer is designed to blow air into the attic space and effectually force stagnant, hot attic air out of existing static ventilation and pressurize the attic space. Pressurizing the attic space creates a vapor seal between the living space and the attic. Sealing, by pressure, the living space from the attic space.
 The main component of the invention is the solar module (1). The solar module must be between 30 and 55 watts of power per system. The solar module must be 12 volt dc nominal which translates to a Voc of 16-20 volts dc. Crystaline or thin film technologies are equally effective and may be used assuming the voltage is of acceptable range. Frame mounting of the module must be easily accomplished by using "Z" clips. A power cord of 2-wire UV/heat resistant wire #16awg minimum (2) 30 feet in length with a 2 pin locking electrical connector (3) must be installed on the solar module.
 Another main component is the 12 volt dc inline 4'' blower (5). Easily available from manufacturers such as Attwood, Rule, and Sea Choice to name a few. Blower fan should be rated for up to 50 watts of power with an in system flow rating of over 100 CFM of air. Wire leads will have the matching connector installed to mate to the solar module wire lead (4). All existing blower fands and any future custom made blowers will have mounting feet to allow for a horizontal attachment to either joist or truss.
 The 4''flexible duct tubing is readily available from both the marine industry and also used as a flexible dryer vent ducting (6).
 The tin manifold will be a manufactured piece that transitions from a 4 inch round end to a 2 inch×6 inch rectangular end. The rectangular end must be a minimum length of 12 inches to ensure that the open end can be pushed well clear fo the header wall and into the eve/soffet area of the building (7).
