Infinitum Electric’s IEq is an alternative solution to replace VFD based on insulated gate bipolar transistors (IGBT). High-efficiency silicon carbide (SiC) VFD provides a small, smart, cool and efficient motor controller integrated with IoT functions in one unit.
The introduction of VFD enables commercial and industrial applications to change the speed of fan, pump or compressor applications. This has led to gradual changes in the overall energy consumption of the industry. However, there is still a limiting factor-VFD efficiency stagnates at about 88-94%.
Infinitum’s new silicon carbide IEq improves motor control efficiency, size and packaging, allowing OEMs and end users to deploy the technology in a more diverse environment. In addition, it also includes tightly integrated IoT sensors for vibration, temperature, power, etc., a microcontroller and a one-way “data diode” IoT cellular modem gateway, which allows OEMs and end users to supervise multiple facilities, thereby Easier to aggregate this data across thousands of installations, you can gain a deeper understanding of the performance and reliability of their applications. The onboard controller analyzes high-speed IoT sensor data in real time to provide end users with real-time predictive analysis. This innovation allows many OEMs to rethink how to deploy VFDs in new ways that were previously unavailable.

Company: Advanced Cooling Technologies Inc. Innovation: Pump-assisted split-flow energy recovery heat exchanger
Advanced Cooling Technologies’ pump assists AAHX to recover energy from exhaust or supply air in all seasons, so that AHU consumes less energy. It works by combining traditional air-to-air heat pipe technology with a pumping two-phase system using two operating modes. In passive mode, when the hotter air flow is actually below the colder air flow, the mode will be activated, and the heat exchanger operates as a heat pipe without the need for electrical input. When the season changes and the relative temperatures of the two air streams are opposite, a small pump will be used to maintain energy transfer. Since the method of heat transfer inside the heat exchanger utilizes the latent heat of the working fluid, the flow required to transfer a large amount of energy is a small part of the equivalent glycol circuit. The combination of passive operation for at least half a year and the extremely low energy consumption during the other half of the year for active operation can make the product obtain such a high overall energy recovery rate.
The heat exchanger is compatible with large systems or long distances. In addition, optional active control valves and pump control devices enable the heat exchanger to provide relatively accurate temperature control and defrost functions without the need for inefficient bypasses. This innovation solves some of the problems in the HVAC industry, such as allowing clean air without being polluted by cross air. It uses two-phase heat transfer technology with high efficiency and high performance, and reliability is increased through redundancy and fluid selection. It also eliminates the limitations of current system designers in hardware configuration, and therefore eliminates the need to compromise system packaging and energy recovery. This innovation will allow designers to free up more time to develop new system layouts to better distribute the building’s air and return, and to optimize the airflow in their applications without sacrificing energy efficiency.

The Radiation Automatic Balancing System (RABS) introduces the function of monitoring the temperature of each loop in the radiation system. Combined with monitoring the air temperature in each area through a wireless thermostat, the control uses a learning algorithm to drive and regulate the flow of water to each circuit to improve the efficiency of radiant installation. Loop lengths no longer need to be designed to be similar lengths, nor do they need to be manually balanced using flow control on the manifold. Although it is still best practice to design circuits of similar length, the design rarely takes furniture and temporary floor coverings into consideration. The system does not require user input to maintain the set temperature by changing these variables, thereby providing designers with greater flexibility without reducing efficiency.
This innovation will provide an ideal solution for customers seeking efficient radiation. The system also integrates more digital pipelines for end-user monitoring, and more and more customers want more interesting and useful data related to their system performance. In addition, the system will save installers valuable time when balancing the radiation system. Once the system is connected to the manifold and web application, the customer can make changes and monitor the temperature.

The Des Champs Technologies series PLP Air-Trap™ provides a new concept in the condensate collector design, which can remove condensate from air conditioners or other condensing equipment, while blocking air circulation throughout the year, and only requires 2 7/8 inches High can get 0-40 inches of positive water column pressure. The trap will never “dry out” or freeze because it does not rely on water to seal, but only on fan pressure.
The innovative PLP trap uses the air pressure generated by the A/C fan to prevent conditioned air from entering or leaving the equipment. PLP is specially designed for HVAC equipment and does not require water to prevent air leakage. Air conditioning equipment mainly generates condensate in summer. For the rest of the year, little or no condensate is produced, and when no condensate is produced, the PLP is in a dry state and uses a lever-type horizontal pancake design float valve with mechanical advantages around the pivot point.
