The Beginning and Evolution: PAFMAC Story
3.4 Development of PAFMAC
The biggest difference between the previous PFAS lies in its specific design for hotel rooms.
3.4.1Specs demanded by the customers
Solutions to the unsatisfactory areas of AC discovered by the guest complaints
- Adjustable to preferred temperature all year round and at any time.
- Adjustable by 1 degree increments to a preferred temperature.
- Adjustable air volume. (Strength)
3.4.2 Needs of hotel management company and AC engineering firms
- Minimize revenue loss: Minimize out of order rooms due to construction to only the floor being worked and floors above and below with 30 day construction requirement for 1 floor with 33 rooms.
Have construction while keeping the hotel business open for guests.
- Maintain current effective working space: AC upgrade without expanding current machine room and piping space.
- Satisfy planned architectural AC needs: Due to varying room directions, AC system must respond to various cooling and heating needs occurring simultaneously.
- Satisfy rooms’ environmental needs: Must be able to adjust temperature in each room due to varying effective or feel of temperature.
Satisfy varying
temperature preference of overseas guests.
Increase air volume to eliminate temperature imbalances.
Maximize existing pipes to countermeasure increased cooling load
- Compatibility with existing facility
Continue using the existing chilled and heat source receiving facilities
System that delivers all year round dual cooling and heating with 2-pipe chilled/hot water system.
- Cost Benefit
Accomplish all the above at low cost
3.4.3 PAFMAC Specs
・Operable at water temperatures between 45 to 110F°
・Temperatures adjustable by 1 degree increments between 63 to 83F°
・3 levels of air volume strengths: 280, 210, 170CFM
・Fan coil capacity is equivalent to #200 and the heat pump compressor is 300W
・Cooling capacity is 10,000BTU, combining fan coil and heat pump. Heating capacity is 14,000BTU,
combining fan coil and heat pump.
With chilled water supply, the heating capacity is 2,000BTU, and with hot water supply the cooling capacity is 2,700BTU.
・SLEEP MODE was built-in to shut down the compressor during late-nights.
Designing began in September, 1994, and with various internal testing and testing with client observers in attendance, the first unit was delivered in July of 1996.
