![]() ![]() Sensible heat is the heat due to temperature change and latent heat is the heat due to chase change in phase of the water content in the air. Having considered these examples, we got the understanding why cooling systems use refrigerant and why for defining a unit's cooling capacity was decided to use terms 'total capacity' and 'sensible capacity'. For example, if you add some heat to water while it boiling (100☌), the temperature will not increase, but water will be keeping boiling. The heat that was added but not change the state called latent heat, because it doesn’t influence to substance temperature. ![]() But all this changes of states is called latent heat. Improve dehumidification capacity up to 75. Provide up to 90,000 BTU/HR of heating per 1000 CFM of outdoor air. Provides up to 4 tons of cooling per 1000 CFM of outdoor air. That is means that solids go to liquids, and then go to gases. Per ASHRAE guideline V, a typical Airxchange® wheel can improve HVAC system efficiency up to 40, preconditioning outdoor air at efficiencies equivalent to 60 EER. For example, ice can become water and then water can become vapor. ![]() State of all nature substances is changeable. ![]() Heat that causes a change in temperature in an object is called sensible heat. Sensible heat is an increasing or removing heat of the object. The recovered heat can be redirected for various heating applications, which saves energy while maintaining conditions.TERMINOLOGY HEAT TERMINOLOGY Sensible heat When there is a simultaneous need for chilled water and hot water, these chillers have the capability to operate in heat recovery mode. How It Worksĭuring cooling only operation, the chiller produces a controlled source of chilled water leaving the evaporator while dissipating heat through the condenser and ultimately to the environment. Carrier chillers with heat reclaim capabilities can do just that produce chilled water controlled to the necessary temperature while generating hot water as a by-product of the chilled water system. There is a more efficient means of generating hot water through the application of chiller systems with heat reclaim capabilities. If a more efficient means of providing heat could be implemented it would represent a tremendous opportunity to reduce energy consumption in buildings and thus reduce total energy consumption. Of the energy consumed in commercial buildings, 43 percent is used for space and water heating. Buildings are responsible for 40 percent of total energy consumption. ![]()
