A burner assembly for providing a flame and combustion gas to a plurality of inlets includes a burner frame having a channel formed therein. The channel extends parallel to a longitudinal plane defined by the plurality of inlets. A burner is mounted within the channel of the burner frame. The burner is arranged in fluid communication with the plurality of inlets. A burner bracket is used to mount the burner assembly within a burner box. The burner bracket defines a cavity within which the channel of the burner frame and the burner are positionable.

Inward fired low NOpremix burner

A heating system includes a refrigerant boiler including a heat source for heating a refrigerant from a liquid state to a vapor state, a boiler outlet and a boiler inlet; a heat exchanger in fluid communication with the refrigerant boiler, the heat exchanger including a upper manifold having a heat exchanger inlet coupled to the boiler outlet, a lower manifold having a heat exchanger outlet coupled to the boiler inlet and a plurality of tubes connecting the upper manifold and the lower manifold, wherein refrigerant passes from the upper manifold to the lower manifold via gravity; and a fan moving air over the heat exchanger to define supply air for a space to be heated.

Heating system including a refrigerant boiler

A discharge gas manifold having a main conduit, an end feeder conduit, and at least one intermediate feeder conduit, wherein the at least one intermediate feeder conduit contains a portion, adjacent to the main conduit, that forms an angle between 0&#xb0;-60&#xb0; with the axis of the main conduit.

Discharge gas manifold for use with multiple compressors

An air conditioning unit test system includes an a multi-sub-system air conditioning assembly including a plurality of sub-systems for conditioning an indoor environment. The a multi-sub-system air conditioning assembly includes a control board having control circuitry for controlling the plurality of sub-systems. The air conditioning unit test system includes a remote test communications device connected to the control board via a data communications link. The control board is configured to perform a configuration of tests for testing sub-systems of the multi-sub-system air conditioning assembly based on receiving a test request from the remote test communications device, to test the sub-systems based on the configuration of the tests, and to transmit results of the tests to the remote test communications device.

Discharge manifold for use with multiple compressors

A refrigerated merchandiser () includes an upright, open-front, insulated cabinet () defining a product display area () connected in airflow communication with a compartment () via an air circulation circuit (). A high pressure drop evaporator () and a plurality of closely spaced fans () are disposed within compartment (). The evaporator () is provided with a relatively high fin density heat exchanger coil providing a relatively high air side pressure drop through the evaporator. The increased flow resistance through the evaporator coupled with the plurality of closely spaced fans results in a substantially uniform evaporator outlet temperature profile across the length of the evaporator.

Medium temperature refrigerated merchandiser

A condenser coil for a refrigerated beverage and food service merchandiser includes a plurality of parallel fins or V-shaped fins between adjacent tubes. In order to reduce the likelihood of fouling by the bridging of fibers therebetween, the spacing of the fins is maintained at a distance of 0.4 to 0.8 inches apart. In one embodiment, the coil includes a plurality of flat multichannel tubes, with no fins therebetween, and the spacing between the multichannel tubes is maintained in the range of 0.4 to 0.8 inches. In one embodiment, the coil includes at least one serpentine shaped, multichannel tubes, with no fins therebetween, and the spacing between flat, parallel segments of the multichannel tubes is maintained in the range of 0.4 to 0.8 inches.

Foul-resistant condenser using microchannel tubing

A refrigerated cold beverage merchandiser () includes an enclosure defining an insulated, refrigerated display cabinet () and a compartment () heat insulated therefrom wherein a compressor () a condenser () and a condenser fan () are disposed. The condenser () is formed by a plurality of in-line tube banks (). Each tube bank () is a serpentine tube formed a plurality of unfinned, straight tube segments () extending in parallel rows () between a pair of spaced, opposed end plates () and elbow turns () connecting neighboring straight tube segments () in a conventional manner. Each successive tube bank () is arranged with the other tube banks so that respective parallel tube rows () are disposed in-line from the front to the rear of the condenser () or with each successive tube bank being offset in a slightly staggered arrangement.

Refrigeration system has a display case that defines a display space. The display space has a top area, a bottom area, a front viewing area, and a back area. A cooling element provides cool air to the display space through a series of fans that direct the air to an air outlet. The air outlet then directs the air to an air inlet, thereby forming an air curtain across the front viewing area. A light is located near the back area away from the air curtain. A mirror is spaced from the light and reflects light from the right source through the display space.

Refrigeration system having rear light source with reflector

A condenser coil for a refrigerated beverage and food service merchandiser includes a plurality of parallel fins between adjacent tubes. In order to reduce the likelihood of fouling by the bridging of fibers therebetween, the spacing of the fins is maintained at a distance of 0.4 to 0.8 inches apart. In one embodiment, the tubes comprise microchannel tubes, with no fins therebetween, and the spacing between the microchannel tubes is maintained in the range of 0.75 inches to optimize the heat transfer performance while minimizing the occurrence of fouling. A supporting structure is provided between microchannel tubes when no fins are included. Also, plural rows of microchannel tubes are provided with separate inlet headings and with the rows being staggered in transverse relationship to enhance the heat transfer characteristic while minimizing the likelihood of fouling.

A refrigeration system comprises a display case having a viewing area with the first side and a second side. An air outlet on the first side guides air across the viewing area to an air inlet on the second side. A first fan and a second fan communicate with the air inlet. A volume extends between the air inlet and the first and second fans. The partition divides this volume between the first and second fan.

A refrigerated merchandiser () includes an upright, open-front, insulated cabinet () defining a product display area () connected in airflow communication with a compartment () via an air circulation circuit (). The flow of refrigerant through the coils () of evaporator () disposed in the compartment () to cool the airflow from the product display area of the refrigerated merchandiser.

Evaporator for medium temperature refrigerated merchandiser

Refrigeration system has a display case defining a display space. The display space has a top area, a bottom area, a front viewing area, and a back area. A cooling element provides cool air to display space. An air outlet directs a cool air curtain to an air inlet, across the front viewing area. A light source is located near the back area away from the air curtain. A reflector is spaced from the light source and reflects light through the display space.
