Hotel Cooling (video)

The first few hours of the California Hotel Heat Study revealed how Solar Comfort can potentially cool an existing room over 4 times faster than a room without. Our test results confirm that.

Although it is just one segment of the California Heat Study we found these findings significant enough to warrant its own short video clip.

Guests of the hotel had complained that the rooms were still hot after more than an hour of cooling.
Hotel policy, as an efficiency measure, was not to cool the rooms prior guest check-in. There was no setback on the thermostats so it wasn’t unusual for the rooms to reach 90 degrees.

At the electrical panel, power use monitoring equipment had been attached, allowing an accurate readout of kilowatts used by each of the rooms cooling units.
For additional data and calibration, this part of the test used simple monitors (loggers) placed in each room. Intervals of measurement every minute allowed us to record where each room started and exactly when each room reached the desired temperature.

The Solar Comfort transparent screen was rolled down in one room and the logging began.

After 20 minutes the room with the Solar Comfort had reached the desired temperature and the unit cycled off.
The room without the screen continued to run for an additional 90 minutes before reaching the desired temperature. This would explain the unhappy guests. They assuredly would expect to have a cooled room after an hour and a half.

Solar Comfort was reflecting the radiant heat back out, reducing the incoming solar heat gain, while keeping the cool air in.

In the case of this facility, the installation of this one window screen in each room would be the economical choice. The rooms with the western exposure were not able to cool the rooms when the outside temperatures got above 90º’s. Temperatures in this range are frequent in this Northern California location. If the rooms sit vacant empty for those days, income is lost. Rather than replace the units, Solar Comfort would assist in acclimating the climate quickly while the guests still maintained their view and incoming sunlight. The aging cooling units were cycling half as often, therefore extending their mechanical life as well.

These kind of results demonstrate how using Solar Comfort’s efficiency can be directly translated into reduced energy costs as well as reduced run and cycling time for hardworking cooling equipment.
