Thermal energy storage can be carried out by working fluid adsorbing and desorbing in porous materials. In this paper, the energy storage properties of four refrigerants, R1234yf, R1234ze, R134a and R32, with M-metal organic framework (MOF)-74 (M = Zn, Ni, Mg, Co) nanoparticles are investigated usin From a service and repair standpoint, R1234yf has similar thermal properties to R134a, meaning there are only minor system layout and design differences and faults can be diagnosed using the same methods as R134a. The biggest difference is R1234yf's A2L flammability rating, which means it is mildly flammable for refrigerant R1234yf Different PAG oils with different flow properties (viscosities) are still available for use with refrigerant R1234yf. What makes these PAG oils from Behr Hella Service so special is that they are not only suitable for use with R1234yf, but can also be used with the refrigerant R134a account thermodynamic properties, flamma - bility, toxicity and global warming potential, the list of potential candidates is very limit-ed.

The p-ρ-T behavior of 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) was measured from T = (232 to 400)K with pressures up to 10 MPa using a two-sinker densimeter R1234yf during the early stage of the compression, when the specific volume of the gas is large. This latter effect has resulted in a higher shaft torque required for the case of R1234yf, as shown in Fig. 2(g). Fig. 2(b) shows that the R1234yf has about 25% more mass than R134a. However this 25% more mass indicated b Table 1.

Younger models like Opel Mokka have grown older in the meantime, and wear starts to take its toll With a GWP of 4, and thermodynamic properties that closely match those of R134a, R1234yf would seem to be the ideal solution. Unfortunately, ideal did come with a few drawbacks. Over the past year, as automakers have tried to introduce this refrigerant into new vehicle platforms, both the limited availability and price of R1234yf have been major stumbling blocks and concerns Therefore, this study had adopted molecular simulation methods to investigate the adsorption and energy storage properties of R1234yf, R1234ze(z), R134a and R32, as well as their mixtures in M-MOF.

R1234yf is a synthetic HFO refrigerant co-developed by DuPont and Honeywell as a near-zero GWP successor to R134a for automotive air-conditioning applications. Its global warming potential (GWP) is ultra-low, with a rating of less than 1. This means that one kilogram of R1234yf released to atmosphere has a significantly lower greenhouse effect than a kilogram of carbon dioxide • R1234yf, R32, and R290 have much lower GWPs than R410A. R410A is nonflammable, but R1234yf, R32, and R290 are flammable. Because the burning velocities of R1234yf and R32 are smaller than 10 cm/s, flammability of R1234yf and R32 is mild and it is categorized under the A2L class of the ASHRAE. Refrigerant.
