At Energy Labs, we take DX Technology to a higher level. Our designs represent some of the most energy efficient systems in the industry. With our depth of expertise, we can think outside the box to deliver energy efficient DX systems at 10-25% higher efficiency than conventional DX systems. Our systems can be designed to approach the operating cost of more expensive chilled water systems.
Energy Labs can custom design systems that optimize efficiency in a number of ways. First, we can provide high efficiency condenser fans that precisely ramp up or down in speed to match the load. Next, we don’t just provide a standard compressor/coil combination that may be excessively oversized. Rather, we can optimize multiple compressor and coil designs to shave extra kilowatts off the load. Finally, we can offer both indirect pre-cooled or direct evaporative cooled condenser options that can even more dramatically lower energy usage. When looking for high efficiency DX systems, Energy Labs has the experience to deliver.
Standard size ranges are from 15-400 tons and custom sizes up to 1000 tons. Condenser coils are mounted in a “V” arrangement to maximize the available coil surface area for a given height of unit. Coils are counter flow with integral liquid sub cooling. Standard condenser coils are manufactured with 3/8” diameter copper tubes with a 0.020” tube thickness. Condenser Coils are a minimum of three rows deep with a maximum of twelve fins per inch fin spacing. Fins can be aluminum, or copper with additional special coatings available. All units are available with refrigerants R410 or R134.
HOW WE ARE BETTER
Multi-Wing Variable Pitch Condenser Fan Blades – When you think variable pitch fan design most customers can be forgiven if they think of tunnel ventilation. At Energy Labs, we apply that same high tech fan design to our condensers. As standard this produces a condenser fan that is more efficient and quieter than the typical stamped steel blade used by our competitors. Furthermore, the variable pitch increases the performance range of the condensers should onsite ambient conditions exceed design specs. Finally, the glass reinforced polymer blade will last much longer than steel.
Variable Speed Drives for Head Pressure Control – Rather than just turn fans off to control head pressure, we believe it’s more energy efficient to control the condenser fans with a variable speed drive. It’s certainly more expensive but that’s our commitment to providing the best in custom design.
Maintenance Access – Frequently, maintenance is a secondary concern for the major manufacturers of DX condensing units. At Energy Labs service access for components like compressors, liquid line filters, pressure switches and service valves is a primary design objective and those components are located outside the coil area for maintenance.
Condenser Guard – Condenser coil guards are another standard feature to provide protection for coils from weather related damages and vandalism.
All systems are charged with refrigerant and the system is tested in the factory prior to shipment. For split systems the unit will have to be charged on the job site. All electrical and temperature control systems including sensors and actuators are installed, wired and tested at the factory.
