Latest Patents

Hirata's latest contributions to automotive air conditioning technology include two noteworthy patents. The first patent involves an automotive air conditioner that utilizes a mixed type coolant composed of a higher boiling point coolant and a lower boiling point coolant. This innovative system features a stacking container connected to the upper portion of a receiver for introducing a gas phased coolant, which predominantly consists of the lower boiling point coolant. The design incorporates a two-valve system that allows the air conditioner to operate in two modes: mixing and separating. During the mixing mode, the cooling ability is enhanced as the lower boiling point coolant is introduced into the refrigerant circuit, while the separating mode reduces energy consumption by isolating the lower boiling point coolant in the container.

The second patent focuses on an automotive air conditioner using a non-azeotropic mix-type refrigerant, which adjusts its cooling capacity by varying the proportion of the higher boiling point refrigerant and the lower boiling point refrigerant. This system utilizes a heat exchanger with rectifying and cooling means, effectively managing refrigerant proportions to optimize performance based on cooling demands.
