Chick Master has developed a highly successful and efficient system that recovers heat from the developing embryos and recycles it into the incoming hatchery air. This is achieved by removing the heat from the warmed water cooling return line using a heat recovery coil. The warm water return is channelled through the coil passing the incoming cold air over the coil. The result is a double benefit since we not only have warmed incoming air that requires little or no extra heating, but the warmed water in the heat exchanger returns to the chiller colder. We are saving valuable gas or oil energy for the heating of the incoming air and we are also saving valuable electrical energy from the much reduced or virtually eliminated use of the water chillers. This form of heat recovery is known as primary heat recovery and is responsible for the major share of heat energy recovered and electrical energy saved. In addition to the heat recovered from the primary source, a secondary source of heat recovery can be found in the exhaust air from the setters. There is also heat energy available from the Hatcher exhaust air which utilizes specialized filtration equipment to facilitate heat recovery from the dirty exhaust air. This is known as secondary heat recovery. This source is also extremely valuable mainly due
to the fact that setter exhaust air is
typically around 36°C (96.8°F). Heat recovery made from the setter and
hatcher exhaust air carries absolutely no danger of cross contamination
since the system uses fixed plate heat exchangers that separate the supply
air from the exhaust air. Hatcheries are significant producers of heat
energy. During the incubation of eggs a very large amount of embryo heat is
produced and is traditionally removed using water chillers. As an example, a
hatchery producing just over 3 million chicks per week will produce 800kW of
heat energy. In a typical installation this heat would be removed by two or
more water chillers. Since the heat emitted by the eggs is fairly constant,
these water chillers will be working 365 days a year, winter and summer. A
common situation that arises during winter is that the hatchery will be
using electrical energy to remove heat from the return water of the chilled
water system while at the same time using gas or oil heating energy to heat
the incoming air supply. The result is high energy bills, higher equipment
maintenance costs and all of your expensive heat energy being exhausted
through the roof of the hatchery!
