How Water Chiller Works in Arabia
In the scorching heat of Arabia, where temperatures often soar above 40°C and sunlight is abundant year-round, efficient and sustainable cooling solutions are essential for residential, commercial, and industrial applications. Flamingo, a leading innovator in renewable energy-based air source heat pump systems, introduces the R290 DC Inverter Air Source Heat Pump Water Chiller with Photovoltaic Direct-Driven Function. This cutting-edge technology not only delivers reliable cooling but also harnesses solar power to operate efficiently in extreme conditions. Here's an in-depth look at how this water chiller works, tailored to the unique demands of the Arabian climate.
The Core Working Principle: Air Source Heat Pump Technology
At its heart, the Flamingo R290 Water Chiller operates on the principles of an air source heat pump, which extracts heat from the ambient air and transfers it to cool water efficiently. The process involves several key components:
n: The system uses a Panasonic EVI (Enhanced Vapor Injection) DC Inverter Compressor with dual-rotor technology and R290 refrigerant—a low Global Warming Potential (GWP) option that minimizes environmental impact. Ambient air is drawn over the evaporator coil, where the refrigerant absorbs heat, turning from liquid to gas. In Arabia's high temperatures (up to 60°C operational capability), this step is optimized with a 200% increase in cool output, ensuring stable performance even during peak summer heat.
Compression and Heat Release: The gaseous refrigerant is compressed, raising its temperature and pressure. It then passes through the condenser, releasing the absorbed heat to the outside environment while cooling the water circulating through the system. The DC Inverter technology adjusts compressor speed dynamically, saving up to 75% in energy compared to traditional fixed-speed units.
Expansion and Cycle Reset: The refrigerant expands in the expansion valve or tank, dropping in pressure and temperature, ready to absorb more heat. Built-in features like the full DC inverter ultra-quiet fan motor enhance airflow, speeding up heat transfer and maintaining ultra-heat temperature stability.
Water Circulation: Chilled water is pumped through the system via integrated circulation pumps (main and auxiliary), delivering cooled water to fan coil units or other endpoints. The chiller supports multifunction connections, including thermostats, three-way valves, and DHW (Domestic Hot Water) pumps, for seamless integration.
This cycle provides trouble-free cooling with automatic setpoint control, short cooling times (supplying cold water in less than an hour), extended operation for sufficient cold water supply, and easy management via a specially designed controller panel supporting multiple languages.
Photovoltaic Direct-Driven Function: Leveraging Arabia's Solar Abundance
What sets the R290 Chiller apart in Arabia is its photovoltaic (PV) direct-driven capability, eliminating the need for grid dependency during daylight hours. Solar panels connect directly to the unit, converting sunlight into DC power to drive the compressor and pumps.
Suggested Solar Panel Configurations: For optimal performance, Flamingo recommends specific setups based on horsepower (HP). For instance, a 3HP unit requires 8 panels at 230V (3600W total), while a 10HP model needs 12 panels at 400V (10800W). Panels can be wired in series for higher voltage or parallel for increased power, ensuring at least 90% of the heat pump's consumption is met by solar input (minimum DC 300V input for single-phase, 350V for three-phase).
Energy Efficiency in Harsh Conditions: In Arabia's intense sunlight, the system achieves maximum efficiency, reducing electricity costs and emissions. The R290 refrigerant, with its low OWP and no damage to the ozone layer, aligns with global sustainability goals, making it an eco-friendly choice for regions prioritizing green energy.
Why It Excels in Arabia: High Efficiency and Reliability
Arabia's climate poses challenges like dust, extreme heat, and high energy demands for cooling. The Flamingo R290 Chiller addresses these head-on:
Eco-Friendly and Highly Efficient: R290 offers lower emissions than traditional refrigerants like R32 or R410A, with efficiency up to 34% higher. It's compatible with existing fan coil units, ideal for retrofitting without replacement.
Advanced Features: Wi-Fi function for remote control, RS485 signal connection for smart integration, built-in water pumps and expansion tanks, and IPX4-rated waterproofing ensure durability in dusty or humid environments.
Performance Specs: Models range from 6.2kW to 24.1kW cooling capacity (at A35°C/W18°C), with EER (Energy Efficiency Ratio) values from 3.93 to 4.05. The unit maintains controlled water temperatures from 10-20°C, perfect for air conditioning in homes, offices, or businesses.
Additional perks include a huge evaporator with over 40% larger heat exchange area for stronger cooling in ultra-high temperatures, and a clear controller for easy on/off, temperature setting, and mode selection.
