Company: Infinitum Electric
Innovation: Infinitum Electric IEq, a High-Efficiency Silicon Carbide VFD
Infinitum Electric’s IEq is an alternative solution to replace insulated gate bipolar transistors (IGBTs) based VFDs. The high-efficiency silicon carbide (SiC) VFD offers a small, smart, cool, and efficient motor controller with integrated IoT capabilities in one single unit.
Introduction of VFDs allowed both commercial and industrial applications the ability to vary the speeds of fan, pump, or compressor applications. This led to a step-change improvement in the industry’s overall energy consumption. However, one limiting factor remained —the VFDs efficiency stagnated at ~88-94%.
Infinitum’s new Silicon Carbide IEq delivers improvements to motor control efficiency, size, and packaging enabling OEMs and end-users to deploy the technology in more varied environments. Additionally, it includes tightly integrated IoT sensors, for vibration, temperature, power, etc., a microcontroller, and a one-way “data diode” IoT cellular modem gateway, which enables OEMs and end-users overseeing multiple facilities to more easily aggregate this data across thousands of installations, enabling deeper insights into the performance and reliability of their application. The on-board controller analyzes the high-speed IoT sensor data in real-time to provide immediate predictive analytics back to end users. This innovation allows a wide range of OEMs to rethink how they deploy VFDs in new ways not previously available.

Company: Advanced Cooling Technologies Inc.
Innovation: Pump-Assisted Split Loop Energy Recovery Heat Exchanger
Advanced Cooling Technologies’ Pump Assisted AAHX recovers energy from either the exhaust or supply air stream during all seasons, allowing AHUs to consume less energy. It works by combining traditional air-to-air heat pipe technology with pumped two-phase systems that take advantage of both operational modes. In passive mode, which activates when the warmer air stream is physically below the cooler air stream, the heat exchanger operates as a heat pipe with no electrical input required. When the seasons change and the relative temperature of the two air streams is reversed, a small pump is utilized to maintain the transfer of energy. Since the method of heat transfer inside of the heat exchanger utilizes the latent heat of the working fluid, the amount of flow rate required to transfer larger amounts of energy is a fraction of an equivalent glycol loop. The combination of passive operation for at least half of the year and very minimal energy consumption during active operation for the other half of the year enables such high overall energy recovery from this product.
The heat exchanger is compatible with large systems or distance. Additionally, optional active control valves and pump controls allow the heat exchanger to provide relatively precise temperature control and defrost capabilities without the need for volume inefficient bypass. This innovation solves some of the HVAC’s industry’s issues such as allowing for clean air with no cross-air contamination. It is highly-efficient and has high-performance ratings using two-phase heat transfer, and it has added reliability through redundancy and fluid selection. It also removes the restrictions on hardware placement that current system designers struggle with, therefore also removing the need to trade off system packaging and energy recovery. This innovation will free up designers to develop new system layouts for better building air distribution and return, as well as allow for the optimization of air flow in their application without having to sacrifice energy efficiency.

Innovation: Radiant Auto-Balancing System
The Radiant Auto-Balancing System (RABS) introduces the ability to monitor the temperature of every return circuit in a radiant system. Coupled with the monitoring of each zone’s air temperature via wireless thermostats, the control actuates flow of conditioned water to each loop using a learning algorithm to increase the efficiency of a radiant installation. Circuit lengths no longer need to be designed to be similar lengths or manually balanced using flow controls on the manifold. Even though designing similar length circuits is still best practice, designs rarely account for furniture and temporary floor covering. The system maintains set temperatures through changes in these variables without user input, giving designers more flexibility without loss of efficiency.
This innovation will offer a desirable solution to customers seeking high efficiency radiant. The system also incorporates more digitalization of plumbing for monitoring by end users, something that is sought after more and more by customers looking to have more interesting and useful data related to their system performance. Additionally, this system will save installers valuable time when balancing a radiant system. Once the system is connected to a manifold and the web application, the customer has the ability to make changes and monitor temperatures.

Company: Des Champs Technologies
Innovation: Des Champs Technologies Series PLP Air-Trap™
Des Champs Technologies Series PLP Air-Trap™ offers a new concept in condensate trap design that permits condensate removal from A/C or other condensing equipment while blocking airflow all year and requires only 2 7/8 inch height for positive 0-40 inch water column pressure. The trap can never “dry out” or freeze because it does not depend on water to seal, only fan pressure.
The innovative PLP trap uses air pressure developed by the A/C fans to prevent conditioned air from entering or leaving the unit. The PLP was designed specifically for HVAC equipment and does not require standing water to prevent air leakage. A/C equipment produces condensate mostly during summer. The remainder of the year little or no condensate is produced, and the PLP operates dry when no condensate is being produced and uses a levered, horizontal pancake designed float-valve with a mechanical advantage about a pivot point.
