From the time the emergence, the hotel/castle constructed completely of made ice in Sweden has turned into a fad in northern states. As an HVAC technician near one such ice hotels it has fallen to me the last several years to try to heat the rooms while not really compromising the ice. People are drawn to the exotic nature of the building made of ice but as it turns out they are not big at freezing while they stay their time there. Obviously you can’t have anything that’s going to produce too much heat if you can’t have anything melt. It was no easy task to heat a place without heating it. The first year we just used electric blankets on the bed but this only helped while folks were sleeping. This year I came across a genius solution. The first part involved building a skeleton of the building along with pipework. I was going to utilise the hydronic method, using refrigerant lines running through the pipes. The water would be pumped through the pipes continuously in order that it will provide structural integrity for ones icework and keep it cooled. So this solves the difficulty of keeping the structure intact. To warm the room I decided that the easiest way would be by use a line infrared space heater. These heaters are connected to thermostats restricted to safe temperatures for your rooms. I also designed some winter release vents incase the the temperatures of the rooms exceeded the prescribed heat. All of this design and additionally HVAC framework was very trial and error in these circumstances. It turned out to be a fantastic success and I actually made a name for myself along the way. Now ice castles all within the U. S. are using my own framework. I never thought I’d acquire acclaim as an HVAC computer technician.
