An evaporator blower for air conditioning system that can be installed into a ceiling between existing joists. The system has a chassis dimensioned to fit between the pair of joists forms an air flow pathway through which air may be cooled by an evaporator housed in the chassis. A mounting flange is pivotally coupled to the chassis and has an opening through which the chassis can pivot between a first position below the mounting flange, and thus the ceiling, to a second position above the flange, so that the chassis is above the ceiling and between the pair of joists. A diffuser is attached to the mounting flange and provides supply and return air grilles that are in fluid communication with the air flow pathway of the chassis.

An air conditioner and filtering unit produces a positive or negative pressure to create an isolation space. A common air intake plenum has first and second inlets for admitting return air from the space or outside air which may be from a building main A/C system supply. Sanitized, cleaned and conditioned air is returned to the conditioned space; and condenser air is exhausted outside the conditioned space. The air intake plenum may be common to both the condenser air flow and to the evaporator air flow. A HEPA filter cleans the air suppled to both the condenser and the evaporator. A slide damper or other arrangement selectively opens and closes air flow through the first and second air inlets into the common intake plenum. This permits creation of overpressure, underpressure, or an intermediate pressure in the conditioned space. All air supplied to the room and all air exhausted from the room is cleaned and sanitized. The unit is self-contained and portable.

High-profile refrigerated floral merchandiser unit

Floral merchandiser display stand

A refrigerated open display case has receptacles or holders for directly receiving wet-pack shipping containers, so that flowers do not need to be repacked into vases. A laminar flow of chilled air over the flowers establishes a laminar flow boundary layer with the warmer ambient air. An array of perforations serve as chilled air supply openings on the vertical riser walls, and chilled air is discharged in a laminar flow. A return air intake grille extends across the cabinet below the front of the lowermost shelf, in an undercut transverse recess. The front part of each shelf member has a chamfer or downward slope. The receptacles for the wet-pack containers can include cutouts that extend onto the chamfered front parts of the shelves. The forward wall of the container is exposed above the chamfer, which facilitates insertion and removal. Inside the cabinet, the coldest air leaving the evaporator coil passes in contact with the underside of the shelf members and with the containers. Alternatively, the containers can be suspended on hangers supported on the perforated vertical walls.

Floral display case for directly employing wet-pack containers

A refrigerated open display case achieves a laminar flow of chilled air over flowers or produce displayed therein, and establishes a laminar flow boundary layer with the warmer ambient air. There is an array of perforations serving as chilled air supply openings on each of the vertical riser walls, so that the chilled air is discharged in a laminar flow. A return air intake grille extends across the cabinet below the front of the lowermost shelf, in an undercut transverse recess. The front part of the lowermost shelf member can have a chamfer or downward slope, so that debris that falls on it drops to the floor in the front of the cabinet, where it can be routinely swept up. The recess below this chamfer can likewise have a slanting lower wall. Inside the cabinet, the coldest air leaving the evaporator coil passes in contact with the underside of the shelf members, so these shelf members are also kept chilled. Vases or flower containers, which can be metal, are positioned in open receptacles in the shelves, with the bottoms of the vases or containers projecting down into the cold air tunnel.
