The Beginning and Evolution: PAFMAC Story



 
3. PAFMAC: The Beginning


Demand for Improving Air Conditioning in Hotel Rooms

The ANA Intercontinental-Tokyo, formerly known as ANA Hotel Tokyo, was built in June, 1986, as part of Akasaka Arc Hills, a commercial and residential complex, with a designation as an international city hotel. The building was built with 2-pipe fan coil air-conditioning system. On the brink of its 10th year anniversary, the hotel conducted an evaluation on the building and facilities against other latest city hotels. From analyzing guest room questionnaire, it was discovered that 96% of the total complaints were related to air conditioning.
 
What it boiled down to was that the room temperature could not be dialed in to guest preference, hot or cold, and also room temperature imbalances were found.
 
In order to resolve the situation in response to the complaints, the hotel considered upgrading to dual  cooling and heating AC system to provide option for switching freely between the two functions.
 
Also, with further analysis, it became clear that it gained cooling load since the time of hotel completion.

Recent PAFMAC Reviews in Japan Part 2 Taken from an article published in the Japanese weekly magazine, “ HOTERES”.   NIPPON SEINENKAN HOTEL Hotel types: City Hotel Guest rooms: 220 rooms New construction     Our previous building was also a two-pipe air conditioning system and it had to be centrally controlled and locked in either cooling or heating mode, and it would take a full day to switch from one to the other mode. Therefore, we were always concerned about the weather every day during the changing of the seasons to determine when to switch from cooling mode to the heating or vice versa. Given this experience, it was critical for us to have a de-centralized all-year-round cooling and heating system, so we had requested it directly to an architectural firm. The ability to switch between cooling and heating anytime throughout the year and to have the flexibility to do it individually in each room. However, if we

Taken from an article published in the Japanese weekly magazine, “HOTERES”. Richmond Hotel Tokyo Mejiro Hotel type: Business Hotel Guest rooms: 145 rooms Guest room renovation Air conditioning was our main focus when renovating.

We were searching for a cooling and heating system that could be interchanged individually in each room while using our existing 2 pipe fan coil system. We were introduced to PAFMAC by an air conditioning consultant. Our hotel converted from 2-pipe fan coil system to PAFMAC.
