quoting Iris: "The conventional wisdom is that if you chill most Phals for a period of two weeks, they will bloom 120 days later. According to this, if I want my Phals to bloom for our orchid show in mid-October, I have to put them on a chilling regimen around Memorial Day. Now there may be no natural chilling available at that time, unless we have some cool weather. I understand it has to go below 59 deg. F. I can't turn on the air conditioning in just one room. If it doesn't go below 59 outdoors, can I put my Phals in the refrigerator overnight (34-40)? Put ice cubes in the pot? Any other ideas?"
Dr. Wang did some phal chilling tests. Indication of testing was a drop in night temps some 25 degrees F lower than daytime temps, as my poor mem recalls. Lower temp of 50-55 with daytime around 80. Chill time limited to around 12 hours in dark, then warm in daylight period. But your 34-40 seems a bit too cool.
