Processes and systems for improvements on the efficiencies of convection ovens utilizing exhaust heat recuperation in the form of heat exchangers and premixed combustion systems, and a combination thereof. The heat exchangers and premixed combustion systems allow for increased efficiency of use of fuel and gaseous mixtures within convection oven cavities for improved heating capabilities and decreased efficiency losses.

High efficiency convection oven

A system and method for the treatment and disposal of condensate, particularly acidic combustion condensate, are provided. A neutralizer connected with respect to a condensate flow can be used to treat the condensate flow to provide a supply of neutralized condensate to a transfer chamber. Neutralized condensate can be conveyed from the transfer chamber to an ultrasonic atomizer such as via capillary action by way of a wicking assembly. The ultrasonic atomizer is used to produce an atomized neutralized condensate that can be directly discharged or released at a controlled rate, decoupled from condensate generation, and appropriately disposed or utilized (e.g., humidification).

Ultrasonic condensate neutralization and disposal system

An apparatus and system for a combination space and water heater including a controller device and a method for control. The controller device is a self-contained system that can be added to, or in combination with, existing water heaters and hydronic air heating systems using standard plumbing connections, and provides a potable water system without any need of an intermediary heat exchanger. The controller device automatically monitors a heating capacity of the water heater and the hydronic heating coil over time, and correlates measured heating loads with one or more environmental temperatures, thermostats, user settings, and/or a supplemental heating system.

Control apparatus and method for combination space and water heating

An electronic expansion valve (EEV) is operated by a motor controlling a variable restriction valve in which a liquid refrigerant enters at a high pressure and exits at a reduced pressure. The motor controls the depth of a tapered needle which, as extended, penetrates multiple fixed orifices, aligned in series. Additional fixed orifices, downstream of the fully extended needle, provide further restriction and management of refrigerant flashing. Depending on the desired operating range, the following elements may be controlled: needle length, diameter, and taper; diameter, thickness, and relative elevation of each orifice; response and maximum torque provided by the motor; and geometry of the valve enclosed volume.

Electronic expansion valves having multiple orifice plates

A fryer unit combination includes a frying fluid vat and an associated heat exchange system whereby increased or greater efficiencies and/or heat transfers can be obtained and realized. The heat exchange system includes a first heat exchanger arrangement at least in part disposed within the frying fluid vat and a second heat exchanger arrangement disposed externally to the frying fluid vat. In the first heat exchanger arrangement, a heat exchange tube is in heat flow communication with a combustion chamber wherein an associated gaseous fuel burner is at least in part housed. The second heat exchanger arrangement includes at least a first side heat exchanger disposed externally adjacent the first side of the frying fluid vat. The side heat exchanger(s) may permit intake of an oxygen-containing gas such to preheat the oxygen-containing gas prior to entrance into the combustion chamber.

High efficiency commercial fryer

An apparatus for dehumidifying gas is provided which converts humid gas into dehumidified gas using a hydrophilic membrane that includes a superabsorbent polymer. A sub-dew point cooling tower, sub-dew point evaporative cooler and sub-dew point water harvesting system which utilize the apparatus for dehumidifying gas are also provided.

Apparatus for dehumidifying gas and methods of use

An apparatus for heating water having three vertically aligned water heating process sections. The upper section includes an annular water storage tank disposed around a combustion chamber having a downward firing burner. The intermediate section, disposed vertically below the upper section receives flue gas from the combustion chamber, which flue gas is cooled and dehumidified, producing a hot condensate which collects in a passive condensate flow control device disposed proximate the bottom of the intermediate section. The lower section, disposed vertically below the intermediate and separated therefrom by the passive condensate flow control device receives hot condensate from the flow control device, which is used to preheat and humidify air, such as room air, which is then recycled to the combustion process of the upper section for use as combustion air. This passive condensate flow control device uses gravity to inject condensate, thereby facilitating a system design that only requires a single condensate pump.
