[0120] Example 4 - Energy-efficient and cost-effective thermal comfort

[0121] In this example 1, the HVAC system can also be adjusted to achieve energy efficient and cost-effective thermal comfort.

[0122] Different window panes are considered, and the operating temperature data, HVAC system energy consumption for different window panes are calculated. For example, three glazings G1, G2 and G3 with different total solar transmittance (TTS) are considered such that TTS(G1)>TTS(G2)>TTS(G3) is satisfied. For example, G1 is an uncoated base glass and G2 is a TSA3+ window glass with higher infrared absorption and thermal comfort. G3 is a window glass with a reflective coating such as silver.

[0123] The operating temperature is directly dependent on the TTS value of the glazing, which means that the reduction (thermal cut-out) of heat / energy entering through the glazing is greater for premium glazing than for standard glazing. As the TTS decreases, the operating temperature ...

example 5

[0128] Example 5: Thermal Asymmetry Data

[0129] Thermal asymmetry data was determined by sensors for each group of panes P1 , P2 and P4 as shown in Table 2.

[0130] Table 2

[0131]

[0132] For the measurements shown in Table 2, at Figure 26 The thermal asymmetry plot for thermal measurements displayed by the analysis unit of the wireless system is shown in . about Figure 26 , showing the thermal asymmetry for the glazings P1 TSANx, P2 TSA3+ and P3 TSA3+ (in which windshield, side lights and backlight are combined). It was observed that the thermal asymmetry was higher for the reference glazing without any coating.

Abstract

A wireless system (100) for generating a thermal comfort map of a vehicle (102) includes a plurality of high precision sensor devices (104) and a data acquisition device (106). The sensor device (104) is configured to simultaneously measure a plurality of parameters, such as air temperature, air velocity, relative humidity, black ball temperature, surface temperature, surface heat flux, solar radiation, and net radiation. Preferably, at least one of the sensor devices (104) is embedded in a windshield of the vehicle (102). The data acquisition device comprises a transceiver unit (114), a storage unit (116) and an analysis unit (118). The data acquisition device is configured to calculate data including an average radiation temperature, an active temperature, an equivalent temperature, a predicted average thermal sensation index (PMV), and a predicted percentage dissatisfaction (PPD) based on the parameters and to generate a thermal comfort map of the vehicle (102) based on the calculated data and the measured parameters.

Description

technical field [0001] The present disclosure relates to systems and methods for generating a thermal comfort map of a vehicle. More particularly, the present patent disclosure relates to wireless systems to control or modify HVAC systems to achieve thermal comfort with energy savings. Background technique [0002] The background description includes information that may be helpful for an understanding of the present disclosure. This is not an admission that any of the information provided herein is prior art or relevant to the presently claimed disclosure, nor that any document cited, expressly or implicitly, is prior art. [0003] Vehicles have become an integral part of everyday life. Due to increased mobility, people are spending more time in their cars. This has drawn more attention to the comfort of the occupants in the vehicle. The four main comfort levels for occupants are thermal comfort, visual comfort, acoustic comfort and air quality comfort. Of all the comf...
