About This Product

■Summary

Simultaneous cooling/heating multi for cold regions equipped with a new defrosting function and available in models ranging from 224 to 1,000.

■Equipped with the new "Auto Select Defrost" function, which intelligently uses three defrosting methods to maintain indoor comfort.

Depending on the amount of frost formed, the system automatically selects three defrosting methods: Hitachi's unique "hot gas bypass defrosting", the new function "switching defrosting", and "reverse cycle defrosting" to improve comfort during heating. Drive wisely to avoid damage.

■[Versatility] Abundant product lineup

No need to worry about cold weather (simultaneous heating and cooling type, for cold regions) [TNX series] has a lineup of 15 models ranging from 224 to 1000 types. With a complete product lineup, we can handle large office buildings, large hotels, etc. In addition, since models up to 450 are single units, there is no need for connection work between outdoor units.

■[Comfort] Frost amount detection function reduces the frequency of defrosting operation

Inheriting the technology of the TN series, it uses a "frost detection function" to precisely detect the frost buildup on the outdoor unit. This reduces the frequency of defrosting operations, extending heating operation to a maximum of approximately 330 minutes.

■[Comfort] Controls room temperature drop by shifting the defrosting timing

If one of the two refrigerant systems connected to H-LINK II is preparing for defrosting or is in the process of defrosting, the other refrigerant system will not perform defrosting operation until the defrosting operation is completed, and the two refrigerant systems will This prevents the defrosting operation from occurring at the same time.

■Prevents freezing of the outdoor unit base

A frost/icing suppression heat exchanger is placed below the outdoor heat exchanger. During heating operation, medium-temperature liquid refrigerant is flowed before depressurization to suppress frost and ice formation at the bottom of the heat exchanger, thereby preventing freezing of the unit base.

■[Comfort] Improved stand-up performance the next day

By defrosting the air before shutting down the previous day, you can quickly start up heating the next day.

■Realizes quick heating start-up

With its high heating start-up performance, it provides a comfortable heating environment even on cold winter mornings.

■Large capacity + gas injection compressor

By adopting a gas injection cycle for the scroll compressor, we have improved heating performance at low outside temperatures without using a combustor or electric heater.

■Hot gas bypass circuit

Newly equipped with a hot gas bypass circuit. Defrosting operation can be performed without changing the four-way valve during defrosting operation, while maintaining the heating cycle. There are other model numbers as well.
