The Cooling principle
The compressor compresses 45F low-temp. & low-pressure refrigerant vapor to 113F high temp. & high pressure vapor then flows into condenser. In condenser cooling water absorbs the heat from refrigerant vapor condensation process and its temperature raises from 86F to 95F. Then the heat will be discharged to air through cooling tower.
After condensation, 91.4F refrigerant becomes into 42.8F low-temp. & low-Pressure liquid after throttle valve. The refrigerant enters evaporator and evaporates immediately. It absorbs heat from the chilled water and makes chilled water drop from 54F to 45F. After evaporation, the refrigerant gas flies into 45F vapor and sucked into compressor. Then next cycle begins.
The Heating principle
The compressor compresses 57F low-temp. & low-pressure refrigerant vapor to 131F high temp. & high pressure vapor then flows into condenser. In condenser cooling water absorbs the heat from refrigerant vapor condensation process and its temperature raises from 104F to 113F. Then the heat will be discharged to central air conditioning users.
After condensation, 109F refrigerant becomes into 55F low-temp. & low-pressure liquid after throttle valve. The refrigerant enters evaporator and evaporates immediately. It absorbs heat from the low temp. water and makes low temp. water drop from 68F to 59F. After evaporation, the refrigerant gasifies into 57F vapor and sucked into compressor. Then next cycle begins.

Gansevoort Meatpacking Hotel in New York City
Project Background
The Gansevoort Meatpacking is an iconic hotel that has been called New York City home since 2004. The 186-room hotel features a full-service ground-floor restaurant, a year-round rooftop bar and restaurant, a 45-foot heated outdoor pool, and indoor and outdoor space where guests can enjoy unobstructed, 360-degree views of the Manhattan skyline.
Located on Ninth Ave and 13th Street, Gansevoort is an anchor in Manhattan’s vibrant Meatpacking District, which has transformed from an industrial district into a hub for fashion, design, culinary excellence, and the arts.
The property is just stepping away from the Hudson River, the High Line, Little Island, premium shopping and dining, the Whitney Museum of American Art, Chelsea Market, and more. The property has completed a top-to-bottom renovation touching all floors, accommodations, and public spaces.
Project Description
This gas-fired absorption chiller system includes two 66-ton cooling capacity BROAD absorption chillers for heating and cooling the building with the COP 1.35 and absorbers can provide heat up to 200F with 0.93 COP.
The chiller would provide more efficient cooling at off-peak hours and at low operating costs when compared to already installed chillers.
BROAD maglev chiller would be replacing the job of the previously installed chillers during summertime and act as the sole cooling provider while the other two chillers would be used for heating purposes.
Project Value
The maglev chiller has a low operating cost and is only going to be running solely for the summer season, thereby lowering energy consumption, and fulfilling its Environmental and Social responsibilities.
It saves 1825MMBTU/534,825.625kWh of fuel by reducing the usage of absorption chillers in the summer season, thus the cost saved by replacing the absorption chillers is $ 127,773.55 and we are using 180,312.192 kWh of electricity.
As a result of this, a total of 354,513.433 kWh is saved. System carbon dioxide reduction is 251 Metric tons* which is equivalent to 66 cars pulled off from the road every year* or 300 acres of U/S forest carbon sequestered per year*.
* Results are based on the US EPA CHP Energy and Emissions Savings Calculator, which may vary from the actual operation data.
Project Highlight
Selected as a general contractor, we designed and built this project and successfully commissioned the chiller. We installed BROAD’s maglev chiller in the hotel, which allows the compressor to operate without using oil for lubrication and making it frictionless.
It is equipped with multiple two-stage centrifugal Danfoss compressors. No oil enters the evaporator or the condenser, which reduces energy losses due to friction and increases the heat transfer efficiency of the chiller. The built-in Variable Speed Drive on the motor allows the compressor to operate much more efficiently at partial loads. The oil-free system also eliminates the need for oil maintenance, resulting in operations and maintenance savings.
The new BROAD chiller’s IPLV is 0.35kw/Ton. Additionally, it consists of modular and multipiece rigging through regular elevators and doors. The single piece of the new machine weighs less than 2000 lbs. leading to reduced capital cost. The oil-free maglev chiller is ideal for building retrofitting or new construction projects.

Project Conclusion
Koach Grow House in California
Project Background
Koach Grow House is an innovative greenhouse project located in the Inland Empire region of California, with a focus on cultivating medicinal marijuana. Serving as its initial phase, this greenhouse complex has plans to expand through the incorporation of three additional phases.
This project has been strategically positioned in California, a state that has experienced a heightened interest in maglev technology due to the significant peak-hour electricity rates charged by local utility companies.
Project Description
The Koach Grow House poses a continuous 24/7 challenge for greenhouse cooling, necessitating innovative energy solutions.
This facility has implemented a 1 MW CHP system, which stands as a crucial component for the daily operation and success of the plant. The CHP system functions as the primary energy source and currently generates over 100% of the facility’s electricity requirements.
The core of the project revolves around the utilization of a microturbine for on-site electricity generation. Concurrently, an absorption chiller will be seamlessly incorporated to produce chilled water during daytime hours.
Remarkably, during off-peak nighttime hours when utility electricity costs are merely 6 cents/kWh, the microturbine operation is suspended, enabling BROAD Maglev chiller to smoothly take over. This dynamic approach ensures optimal operational costs and highlights the flexibility and adaptability of the cooling system.
Project Value
Koach Grow House employs BROAD maglev chiller during off-peak hours, conserving energy by not operating the absorption chiller during this period. As a result, the absorption chiller operates for a maximum of 4380 hours and saves 6342 MMBTU of fuel by reducing its use during off-peak hours. The system achieves a carbon dioxide reduction of 822 tons*, which is comparable to removing 163 cars from the road each year*, or equivalent to the annual greenhouse gas emissions generated by 87 homes*
* Results are based on the US EPA CHP Energy and Emissions Savings Calculator, which may vary from the actual operation data.
Project Highlight
The Koach Grow House project signifies a noteworthy achievement for BROAD as it introduces its maglev units to the US market.
Located in California, where the appeal of maglev technology has risen due to the steep electricity rates during peak hours established by local utility companies.
Beyond its role as a marketing hub for Maglev technology in California, it is anticipated to accelerate the adoption of this technology nationwide. This pioneering initiative harmonizes seamlessly with the burgeoning trend toward energy-efficient and cost-effective cooling solutions.
