The models included the 80 hp (60 kW) 786, the 90 hp (67 kW) 886, the 101 hp (75 kW) 986, the 104 hp (78 kW) 186 Hydro, the 135 hp (101 kW) 1086, the 146 hp (109 kW) 1486 and the 161 hp (120 kW) 1586. These tractors had a new cab dubbed the Control Center that came standard with air conditioning, heat, and several radio-CB options.
Because today's largest county by area, Pike County, is 788 square miles (2,041 km 2), it is only still possible to form a new county from portions of more than one existing county; McCreary County was formed in this manner, from parts of Wayne, Pulaski and Whitley counties. Kentucky was originally a single county in Virginia, created in 1776.
Packaged terminal air conditioner installed in a residential apartment. A packaged terminal air conditioner (PTAC) is a type of self-contained heating and air conditioning system intended to be mounted through a wall. [1] The first practical semi-portable air conditioning unit invented by engineers at Chrysler Motors. It entered the market in ...
The study of the behavior of air-water vapor mixtures. Water vapor plays an important role in energy transfer and human comfort in HVAC design. rooftop unit (RTU) A packaged unit that controls both heating and air conditioning. An air handler typically refers to a unit that provides a fan to support either heating or cooling. radiant ceiling panels
A liquid (glycol based) chiller with an air cooled condenser on the rooftop of a medium size commercial building. In air conditioning systems, chilled coolant, usually chilled water mixed with ethylene glycol, from a chiller in an air conditioning or cooling plant is typically distributed to heat exchangers, or coils, in air handlers or other types of terminal devices which cool the air in ...
1937-1948 era Oliver Model 80 agricultural tractor. The Oliver Farm Equipment Company was an American farm equipment manufacturer from the 20th century. It was formed as a result of a 1929 merger of four companies: [1]: 5 the American Seeding Machine Company of Richmond, Indiana; Oliver Chilled Plow Works of South Bend, Indiana; Hart-Parr Tractor Company of Charles City, Iowa; and Nichols and ...
Water is inexpensive, non-toxic, and available over most of the earth's surface.Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing efficient heat transfer over distance with low rates of mass transfer.
Free cooling is an economical method of using low external air temperatures to assist in chilling water, which can then be used for industrial processes, or air conditioning systems. The chilled water can either be used immediately or be stored for the short- or long-term. When outdoor temperatures are lower relative to indoor temperatures ...
