| Investment | Low - Chiller price is high but water distribution system investment is low (design + equipment + installation + commissioning + machine room)
- Small footprint
- Smaller equipment selection (Refer to Energy Saving Comparison)
| High - Chillers are less expensive but customers' self-purchased water distribution system costs high
- Separate hot water system needed
- Prevalently oversized equipment selection
| Higher - Electricity demand is 8~10 times more than that of non-electric chillers
- Need boiler (boiler room) for heating
- High investment on water distribution system
- Prevalently oversized equipment selection
|
| Function | Three functions in one unit - Provide cooling, heating and hot water separately or simultaneously, and automatically adjust all temperatures
| Only two functions in one unit | Only one function - Heat pump has two functions, but its heating capacity is reduced dramatically or even lost when the ambient temperature is low
|
| Energy Efficiency | Energy saving is visible - Ultrasonic flow meters are installed on all pipes (fuel, chilled/heating water, cooling water, hot water) to reflect the energy efficiency directly or indirectly
- The touch screen real-time displays (and records) cooling capacity and energy efficiency
- Dozens of energy saving patents assure initial and long-term energy efficiency, such as auto purge and air vent (without a vacuum pump in the lifespan), plate heat exchanger, upward spraying, refrigerant anti-overflow, turbulator in fire tubes, etc.
- Cooling water system is equipped with water softener and biocide & antisludge auto dosing device to eliminate energy waste and cooling capacity decrease caused by fouling
- Conduct yearly energy consumption investigation and diagnosis for each user
- BROAD reports at least 50% higher energy efficiency based on its energy investigations of thousands of installations
| Energy consumption is not transparent - No flow meters
- No energy efficiency display
- No auto air vent device so energy efficiency drops periodically.
| Not energy-saving - Energy mode is not energy-saving.
- No flow meters
- No energy efficiency rate display
- Tear & wear of moving parts causes energy efficiency decrease
|
| Safety | Risk free - The world's only non-electric chiller with full range of American and European safety certificates
- High temperature generator is equipped with 8-level mechanical and electronic anti-explosion devices to ensure no explosion (even in case of sabotage)
- Cooling water system is equipped with auto biocide device to eliminate legionnaires
| Risky - Not completely certified
- No comprehensive anti-explosion measures
- No biocide dosing
| Risky - Explosion risks for compressors
- Working under positive pressure condition
|
| Reliability | Pursuing "zero fault" - The annual "tube freezing" rate in evaporator is as low as 0.05%, as it is equipped with 3-level temperature sensors, 3-level flow switches and ultrasonic flow meters*
- "Separate heating" reduces number of parts involved in heating by 80%+, and doubles the lifespan of the main shell
- "Auto purge/ vent" prevents metals from corrosion and makes sure no cooling capacity decrease
- Water distribution system is factory made so that industrialization of central air conditioning is materialized. All aspects from designing to component quality control, production, testing, site commissioning and maintenance are integrated into a unified quality control system
- All materials and components are outsourced from world's top manufacturers (quality first at any time)
- BROAD offers free global network monitoring service to customers during chiller's whole lifespan
- Designed lifespan of BROAD non-electric chiller is 60 years
| Many faults - Annual "tube freezing" rate exceeds 5%
- Main shell heating brings many faults and short lifespan
- No auto air vent device causes periodical cooling capacity and energy efficiency decrease
- Water distribution system is designed individually, purchased separately and installed by non-professionals with quality risks
- Since it does not have cooling water auto treatment device, the heat exchange tubes can easily get scaled since it must be cleaned by acid, which will easily cause attenuation or even puncture of the heat exchange tubes
| Many faults - Number of moving parts is several times more than that of non-electric chillers, and they are easy to be damaged
- Water distribution system is designed individually, purchased separately and installed by non-professionals with quality risks
- Since it does not have cooling water auto treatment device, the heat exchange tubes that can easily get scaled must be cleaned by acids, which will easily cause attenuation or even puncture of the heat exchange tubes
|
| Uncertain | Customers are worry-free & carefree - A single purchase order to solve all ordering, installation and operation problems
- Automatic operation of the equipment and system makes full-time operator unnecessary
- Provide life-long maintenance & repair, or even operation management service (energy management contract). Life-long quality commitment
| Customers are not carefree - Purchase and installation of water distribution system are troublesome
- The whole system is a combination of products from many manufacturers, make it impossible to actualize automation
- Poor after-sale service
