This invention relates to a portable temperature controlled container comprising a body having a storage compartment, an opening to permit access to the storage compartment and an insulated lid. The container comprises a fan, a heat sink and a first thermoelectric device, as well as a first phase change material and a second thermoelectric device in thermal communication with both the first phase change material and the storage compartment. The second thermoelectric device in thermal communication with both the first phase change material and the storage compartment is operable to transfer energy in the form of heat between the storage compartment and the first phase change material. The thermoelectric devices can be Peltier elements.

Portable temperature controlled container

A method of determining the weight of animals and the development of plants in a controlled environment. The method includes measuring the increase in CO production over a test period. CO production is a measure of the metabolic rate and this is related to weight of animals and development of crops which can often be determined by weight. There is illustrated a poultry rearing house having vents, lights and an air heater. CO sensors are connected to a CO controller and in turn to a central controller. To test the increase in CO production over time, the birds are settled into a passive state with no feed and the lights turned off. The level of CO produced is measured. The vents are closed. After a time, the rate of Co produced is measured and the increase calculated.
