Not so safe, but it all depends where you live in the city and all that. Downtown / midtown is the best, anything else is hit or miss. Areas on Moross St. by Grosse point are just as nice as anywhere else. Also, even though Detroit is arguably the most dangerous city in the country, suburbs are very safe.
Air conditioning tonnage has nothing to do with weight. A ton, as used in the HVAC field, is a term that describes how much heat the AC unit can remove from a home in one hour. The measurement for heat is the British thermal unit (BTU). One ton of air conditioning can remove 12,000 BTUs of air per hour. A four ton unit can move 48, 000 BTUs and so on. Therefore, the more tonnage an AC unit is rated at, the more air it can cool.
It is equivalent to the consumption of one ton of ice per day and originated during the transition from stored natural ice to mechanical refrigeration. A refrigeration ton is approximately equivalent to 12,000 BTU / h or 3.517 kW.Air-conditioning and refrigeration equipment capacity in the U.S. is often specified in tons (of refrigeration). Many manufacturers also specify capacity in BTU / h, especially when specifying the performance of smaller equipment.Redirected from Refrigeration ton). A ton of refrigeration (commonly abbreviated as TR) is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment.
