Embodiment 1

[0344] Example 1: Cooling and Heating Performance Data

[0345] The cooling and heating properties of the neat fluids and compositions containing Z-HCFO-1224yd were measured. Measurements include the pressure in the evaporator (Evap) and condenser (Cond), the discharge temperature (Disch T) and the average temperature glide of the evaporator and condenser (Avg Temp Glide). The relative energy efficiency (COP) and capacity (Cap) of mixtures containing Z-HCFO-1224yd (1224ydZ) were measured compared to Z-HCFO-1224yd and pure fluids HFC-245fa, HCFC-123 and HCFO-1233zdE. The results are shown in Table 4 below.

[0346] Data is based on the following criteria:

[0347]

[0348] Table 4

[0349]

[0350]

[0351] The results showed that Z-HCFO-1224yd (1224ydZ) was a good substitute for HFC-245fa, HCFC-123 and 1233zdE. The capacity is very close to 1233zdE. The mixtures shown are also good substitutes for the pure fluids shown, with similar capacities and efficiencie...

Embodiment 2

[0353] Example 2: Cooling and Heating Performance Data

[0354] The cooling and heating properties of compositions containing Z-HCFO-1224yd were measured. Measurements include the pressure in the evaporator (Evap) and condenser (Cond), the discharge temperature (Disch T) and the average temperature glide of the evaporator and condenser (Avg Temp Glide). The relative energy efficiency (COP) and capacity (Cap) of mixtures containing Z-HCFO-1224yd (1224ydZ) compared to HFC-236fa and HCFC-124 were measured. The results are shown in Table 5 below.

[0355] Data is based on the following criteria:

[0356]

[0357] table 5

[0358]

[0359] The results showed that the mixture containing Z-HCFO-1224yd was a good match with both HFC-236fa and HCFC-124. The mixtures shown have similar cooling and heating capacities and efficiencies. The compressor discharge temperature is also similar for the mixture.

Embodiment 3

[0360] Example 3: Cooling and Heating Performance Data

[0361] The cooling and heating properties of compositions containing Z-HCFO-1224yd were measured. Measurements include the pressure in the evaporator (Evap) and condenser (Cond), the discharge temperature (Disch T) and the average temperature glide of the evaporator and condenser (Avg Temp Glide). The relative energy efficiency (COP) and capacity (Cap) of mixtures containing Z-HCFO-1224yd (1224ydZ) were measured compared to HFO-1234yf, HFC-134a and HFO-t-1234ze. The results are shown in Table 6 below.

[0362] Data is based on the following criteria:

[0363]

[0364] Table 6

[0365]

[0366] The results showed that the mixture containing Z-HCFO-1224yd was a good match with HFO-1234yf, HFC-134a and HFO-t-1234ze. The mixtures shown have similar cooling and heating capacities and efficiencies. The compressor discharge temperature is also similar for the mixture.

Disclosed is a mixture comprising the compound Z-1-chloro-2,3,3,3-tetrafluoroprop-1-ene and at least one additional compound selected from the group consisting of HFOs, HFCs, HFEs, CFCs, CO2, olefins,organic acids, alcohols, hydrocarbons, ethers, aldehydes, ketones, and others such as methyl formate, formic acid, trans- 1,2 dichloroethylene, carbon dioxide, cis-HFO-1234ze+HFO-1225yez; mixtures ofthese plus water; mixtures of these plus CO2; mixtures of these trans 1,2-dichloroethylene (DCE); mixtures of these plus methyl formate; mixtures with cis-HFO-1234ze+CO2; mixtures with cis-HFO-1234ze+HFO-1225yez+CO2; mixtures with cis-HFO-1234ze+HFC-245fa; and azeotrope or azeotrope-like compositions. Also disclosed are methods of using the compositions as blowing agents, solvents, heat transfercompositions, aerosol propellant compositions, fire extinguishing and suppressant compositions.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application Serial No. 62 / 547,518, filed August 18, 2017, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to compositions, methods and systems having utility in a number of applications, particularly comprising the compound Z-1-chloro-2,3,3,3-tetrafluoroprop-1-ene (Z-HCFO-1224yd) use of the composition. Background technique [0004] In recent decades, multiple industries have been working to find replacements for the ozone-depleting chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). CFCs and HCFCs have been used in a wide range of applications including their use as aerosol propellants, refrigerants, detergents, expansion agents for thermoplastic and thermoset foams, heat transfer media, gaseous dielectrics, fire suppression and suppression agents, power Applicatio...
