DENSO
| Cooling | Dehumidification heating | Gas injection heating |
| Electric expansion valve | Compact gas-liquid separator | Accumulator |
The compact gas-liquid separating valve separates gas and liquid using the cyclone turbulence effect and the device can be made compact since refrigerant reservoir is not necessary.
The compressor is a scroll-type Denso unit with a refrigerant gas injection port added. The high-density vapor refrigerant is injected into the compressor to increase the mass flow rate and thus improves heating performance.
