Unidad de bomba de calor aire-agua
A reversible outdoor unit that produces chilled or hot water for cleanroom air-handling coils using one refrigerant circuit and ambient air heat exchange.
- Reversible Heating and Cooling
- Air-Source Heat Exchange
- Integrated Hydronic Options
- Seasonal Capacity Modulation
Introducción del producto
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.
Características clave
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.
Soluciones para su aplicación
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.
