Thermal mass


Also found in: Wikipedia.

Thermal mass

A lot of heat energy is required to change the temperature of high-density materials like concrete, bricks, and tiles. They are therefore said to have high thermal mass. Eco designers will strategically place these materials to create heat sinks that absorb heat in the winter and remain cool in the summer. Lightweight materials such as timber have low thermal mass.

thermal mass

Any material or wall that can absorb heat or cold and release it at a later time. Also see roof pond, rock storage, and Trombe wall.

First, thermal mass flowmeters work by measuring the amount of heat that a gas carries away from a heating element as it flows past.
The 780S UHP Ultra-High Purity Thermal Mass Flow Meter provides a variety of self-diagnostic and field-adjustment features, as well as the ability to confirm or "field-validate" the meter's calibration and measurement accuracy in the field.
Features include low thermal mass, fast warm-up, and uniform heating.
The thermal mass of the solder joints at either end of the passive component has a direct effect on the cause of tombstoning.
Because we wanted to learn several different traditional methods for wall infill, we made the northern walls strawbale, for insulation, and southern walls straw-clay and cob, for thermal mass, with large windows for solar gain.
As a gas moves into the chamber of a thermal mass flowmeter, most flows through a bypass tube, while a smaller amount is routed through a capillary sensor tube.
Brooks Instrument's GF40 and GF80 thermal mass flow controllers (MFC) provide enhanced performance, reliability and flexibility in many gas flow measurement and control applications.
To realize the full benefits from your sunroom, you'll need to incorporate the basic dements of passive solar design: orientation, glazing, thermal mass, insulation and ventilation.
Although insulation can enable the different wall types to have similar insulating values (thermal conductivity), the thermal mass of walls, i.e., the quantity of heat it takes to increase or decrease the temperature, can vary greatly.
The use of thermal mass materials is the oldest and simplest strategy for storing heat and naturally mitigating temperature swings.
Unlike velocity meters or thermal mass flow meters, volumetric technology is only able to read flow ranges within a 10:1 flow ratio, also known as the "effective flow range" of the flow meter.
