商品紹介

The air-to-water heat pump reverses refrigerant flow so its water heat exchanger can either remove heat from the chilled-water loop or add heat to a hot-water loop. Outdoor finned coils exchange energy with ambient air, while scroll compressors and electronic expansion control adapt to seasonal conditions. The unit can serve four-pipe changeover coils, cleanroom support AHUs or low-temperature hot-water systems. Heating operation includes frost detection and defrost sequencing to restore outdoor-coil airflow.

主要な特徴

One outdoor package supplies chilled water in cooling mode and low-temperature hot water in heating mode.

Reversible refrigerant circuitry reduces separate boiler and chiller equipment for suitable load profiles.

Variable or staged scroll compressors follow seasonal building demand and improve part-load control.

Integrated defrost management protects heating capacity as frost accumulates on the outdoor coil.

お客様の製品に関する懸念事項

Air-source heating performance changes with outdoor temperature and frost, so water temperature, coil selection and backup strategy must be considered together.

Heating capacity falls during the coldest outdoor conditions.Equipment sizing considers low-ambient capacity and a staged supplemental heat source where required.

Defrost temporarily reduces delivered hot-water capacity.Buffer volume and coordinated multi-module sequencing limit water-temperature disturbance.

A high hot-water setpoint forces excessive compressor lift.AHU coils are selected for the lowest practical water temperature to improve heat-pump operation.

Flow stops while the outdoor unit remains exposed to freezing weather.Flow proof, freeze protection and an appropriate glycol concentration protect the water circuit.
