To evaluate thermal loads, you need to analyze both the external and internal conditions of the spaces to be refrigerated. External loads are caused by the environmental conditions surrounding the space to be conditioned. This includes factors such as outdoor temperature, solar radiation, wind speed, and humidity. These external conditions can affect the heat gain or loss of the space. Internal loads, on the other hand, are necessary to estimate the thermal gains that generate heat inside the space to be air-conditioned. These internal loads can come from various sources such as occupants, lighting, equipment, and processes taking place within the space. By considering both the external and internal loads, you can accurately assess the thermal requirements for air conditioning and design an appropriate cooling system to meet those needs.
