Difference between cold load

1 the building structure of the heat storage properties determine the relationship between the cold load and heat gain. Instantaneous heat gain in latent heat gain and sensible heat gain convection component immediately constitute instantaneous cold load, while sensible heat gain in the radiant component can not immediately constitute a cold load, radiant heat is absorbed by the indoor objects and storage, slowly emitted to the indoor air.

2, air-conditioning load to maintain the heat and humidity of the building environment, at a certain time to supply the cold room called cold load. On the contrary, in order to compensate for the room heat loss to the room supply of heat is called heat load.

3, indoor cold load is mainly the following aspects: lighting heat, human body heat, indoor electric equipment heat, through the glass window into the indoor sunshine, through the glass window of the temperature difference between the heat transfer and maintenance of the structure of the heat transfer instability.
