Z Air-cooled chillers
An outdoor liquid chiller that rejects heat directly to ambient air and supplies chilled water to cleanroom coils without a cooling tower.
- Nenhuma torre de resfriamento necessária
- Rejeição de calor ao ar livre
- Capacidade staged ou variável
- Hidrônica integrada opcional
Introdução do produto
The air-cooled chiller circulates refrigerant between one or more compressors, a liquid evaporator and outdoor finned condenser coils. Axial fans move ambient air through the condenser, eliminating the cooling tower, condenser-water pump and water-treatment loop associated with a water-cooled plant. Scroll compressors suit smaller and modular duties, while screw compressors serve larger capacities. Multiple refrigerant circuits, fan staging and optional variable-speed control improve part-load response and allow the chiller to follow changing cleanroom demand.
Características-chave
Os circuitos de refrigerante independentes fornecem capacidade encenada e reduzem o impacto de um desligamento de circuito único.
Variable condenser fans control head pressure and reduce fan power during mild weather.
As opções hidrônicas de fábrica podem combinar bombas, vasos de expansão e volume tampão em uma base externa.
Soluções para sua aplicação
Air-cooled chillers are simple to site, but their capacity, noise and condensing pressure change with outdoor temperature and airflow conditions.
O ar de descarga recirculado quente reduz a capacidade do resfriador em um telhado lotado.Adequate coil clearance and discharge orientation prevent short-circuiting of condenser air.
A large fixed compressor cycles repeatedly during low cleanroom load.Multiple circuits or variable-speed compression provide smaller capacity steps.
Low chilled-water volume causes rapid temperature swings and compressor cycling.A correctly sized buffer tank or minimum system volume stabilizes the hydronic loop.
Condenser noise reaches nearby occupied areas.Low-speed fan selection, compressor attenuation and night sound modes address acoustic limits.
