A HVAC unit protector apparatus is disclosed. The apparatus may comprise a front panel, a left sidewall that maybe connected to a left side of the front panel such that the left sidewall may fold into the front panel, a right sidewall that maybe connected to a right side of the front panel such that the right sidewall may fold into the front panel, and a top panel that maybe connected to a top side of the front panel such that the top panel may fold into the front panel. The left sidewall, the right sidewall, and the top panel may be connected to the front panel via a plurality of hinges. Further, extendable arms maybe disposed at a top end and a bottom end of the left sidewall and the right sidewall.

The present invention relates in general to the protection of central air conditioning systems during roof demolition and replacement, and more specifically, to a protective roofing shield for an outdoor air conditioning unit and method of use. One aspect of the protective roofing shield includes a framework and canopy that partially encloses the outdoor air conditioning unit to guard against falling debris while not obstructing air flow to the outdoor air conditioning unit to prevent damage to the unit. The protective roofing shield may be adjustable in height and length to be compatible with different sizes, manufacturers and locations of outdoor air conditioning units. The protective roofing shield and method of use is designed to be easily assembled, disassembled, and conveniently transported from one roofing job site to another by a single user to improve efficiency for a roofing contractor.

A ventilation device to be installed outdoors, includes: an air supply fan; an exhaust fan; a heat exchanger; and a casing having an accommodation space that accommodates the air supply fan, the exhaust fan, and the heat exchanger. The casing includes: a partition defining a lower end of the accommodation space and including a first outside air intake port and a first exhaust port each passing through the partition in an up-and-down direction; a bottom plate; an outside air intake chamber defined between the bottom plate and the partition disposed above the bottom plate and that communicates with the first outside air intake port; an exhaust chamber defined between the bottom plate and the partition and that communicates with the first exhaust port; and side plates.

An AC outdoor equipment cover is a protective shade cover for window air conditioners. The device is made from a lightweight durable material, that is both portable and collapsible for shipping and subsequent storage. The device slips around and over the upper part of a window mount air conditioner by forming a sloped cover from the outer distal edge of the external air conditioner housing and the window or building structure above the unit. It is envisioned that this cover will be at an approximate angle of thirty degrees (30°).

The present invention is directed to an exhaust vent assembly including a sleeve, a neck, a damper in the neck, a cap attached to the neck and a collar. The exhaust vent assembly may be configured without any tools and without any penetrative fasteners.

A system for passively exhausting air from a structure includes at least one pair of modules arranged on a roof of the structure. Each module has an exhaust face on one side and a sloped surface on the opposite side, and can receive exhaust air that flows upward from inside the structure. The modules can be arranged in pairs facing one another, with one of the sloped surfaces facing a direction of an environmental flow of air, so that the environmental air can flow up the sloped surface of one module and down the sloped surface of the other module without impinging on the exhaust faces of either module. The pairs can also be arranged side-by-side in an array, which can be expanded with additional pairs of modules to exhaust from the structure at a greater rate.

A wind baffle operable to control air movement to an air inlet of an air-conditioner, the wind baffle comprising: a frame defining an inlet side, an outdoor side opposite the inlet side, and a plurality of wall sections between the inlet side and the outdoor side; a back plate formed on the outdoor side; a first variable air vent formed on a first wall section and being configured to selectively pass or restrict a first air flow through the first variable air vent; a second variable air vent formed on a second wall section and being configured to selectively pass or restrict a second air flow through the second variable air vent; and a securing mechanism on the inlet side configured to attach the wind baffle to the air inlet such that the inlet side faces the air inlet, wherein the inlet side is unobstructed, allowing air to pass freely.
