This page lists hydrofluorocarbon (HFC) and HFC blend refrigerants, and some non-HFC refrigerants. The lists provide: global warming potential (GWP) refrigerant safety classification blend composition ...

The author introduces and analyses the two-phase pressure drop correlation for refrigerant R134a in the condenser of a heat pump heating-cooling system. The following correlation will be included: the ...

where Tc and Pc are the critical temperature and pressure of species i, respectively; Tri = T Tci is the reduced temperature; and ωi is the acentric factor of species i. Viscosity Each component's ...

The temperature and pressure can be detected by monitoring the spectral features of the MI and FPI, respectively. The experimental results demonstrate that the sensor achieves a temperature ...

Cellulose aerogels are highly attractive candidates in various applications, such as thermal insulation, adsorption separation, biomedical field, and as carriers, due to their intrinsic merits of low ...

Fresno County’s Cool Air Rebate Program offers low-income Californians financial help to repair vehicle ACs. Check if you qualify and find a local shop.

As the HVAC industry faces a growing technician shortage, AI and IoT technologies are proving to be powerful tools in bridging that gap. By transforming how technicians approach equipment service — ...

The initial focus of the joint effort is the conversion of shipboard refrigeration and air-conditioning systems presently using CFCs to one of the leading alternative refrigerants, such as HFC-134a.

It can also be used in week light. 3.High precision pressure senso and Digital temperature sensor greatly improve theaccurancy and precision. 4.Micro power electroic component design greatly enhance ...
