Sentence examples for return air temperature from inspiring English sources
Several simulations are conducted to determine the impact of return air temperature, tube wall temperature, and non-uniform refrigerant flow rate.
However, the current simulation method, which fixes the server heat generation and the supply and return air temperature difference of the computer room air handler (CRAH), does not correctly reflect current cooling systems.
We present an auto-regressive moving average exogenous (ARMAX) model that relates the return air temperature and flow rate of an air-handling-unit (AHU) for multi-zone variable air volumes (VAVs).
The return air temperature should be hot, not cold.
The return air temperature shows that during winter mode, the return air temperature is maintained at above 20 °C and during summer time below 30 °C.
Figure 11 shows the monthly average house return air temperature and humidity ratio going back to the solar-desiccant heating, ventilating and air-conditioning system.
Tests are carried out in a representative vending machine system (cassette) at two representative outdoor ambient temperatures of 32.2°C (efficiency test), and 40.5°C (capacity test) and return air temperatures of 2°C, 20°C and 38°C.
When the length scale increased from 0.8 to 1.56 m, the ratio of vertical temperature difference between 2.5 and 0.1 m at the occupied zone to the difference between return and supply air temperature decreased from 0.62 to 0.25.
Open image in new window Fig. 11 Monthly average house air conditions when using the solar-desiccant heating, ventilating and air-conditioning system for the installed system: a return air (RA) dry bulb temperature; and b return air (RA) humidity ratio.
Decreasing the height of return grille will increase exhaust air temperature and significantly reduce the cooling coil load.
The simulation shows that the intake air temperature and return rate of the counter-flow are lower than those of the cross-flow, because the counter-flow arrangement makes the inlet airflow more uniform and the exhaust wind speed is large.
