Title:
AIR CONDITIONING DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/154093
Kind Code:
A1
Abstract:
An air conditioning device (10) for a vehicle is provided with a compressor (1), a condenser (2), liquid piping (3), a pressure reducer (4), an evaporator (5), gas piping (6), and refrigerant that circulates through the compressor (1), condenser (2), liquid piping (3), pressure reducer (4), evaporator (5), and gas piping (6) in the stated order. The refrigerant satisfies the condition 0.93 < (ρ × Δh)/(ρR32 × ΔhR32) ≤ 1, where the density of the refrigerant is defined as ρ, the enthalpy difference of the refrigerant is defined as Δh, the density of R32 is defined as ρR32, and the enthalpy difference of R32 is defined as ΔhR32. The outer diameter of the gas piping (6) has dimensions calculated as 0.3755x + 7.4165 (mm), where the cooling and heating rated capacity is defined as x.
