Product Overview

The COIL – HCM with a fan is a floor convector manufactured by MINIB, s.r.o., designed for intensive heating and cooling of spaces. It features a 2-pipe connection system and is capable of delivering heating outputs greater than 6.5 kW and cooling outputs above 2 kW for a 2-meter length unit. The convector directs air tangentially towards the floor, effectively distributing air up to 3 to 4 meters into the room, providing a cooling breeze effect in summer and active demisting of window surfaces.

Key Characteristics

• Heating output higher than 6.5 kW (for 2 m length)
• Cooling output higher than 2 kW (for 2 m length)
• Directed air flow reaching far into the space (3-4 m)
• Active demisting of window surfaces
• Most powerful floor convector in MINIB’s range
• Implied condensate outlet
• 2-pipe connection system

Dimensions

• Total width: 340 mm
• Construction height: 147 mm
• Length: 900 mm to 2000 mm (various lengths available)

Usage and Installation

The COIL–HCM is intended for spaces requiring intensive heating and cooling. Since May 1, 2009, it is supplied with connection fittings and flexible hoses (3/8") for heat exchanger connection. The 2-pipe connection maximizes heating and cooling performance. The tangential air flow design ensures efficient air distribution near the floor.

Technical Specifications and Performance

Temperature Equations

Heating and cooling outputs are calculated using temperature-dependent equations:

• Heating: Q = QN * ((tW - tA) / 50)^m, where m = 0.9738, tW = mean heating water temperature, tA = mean air temperature, QN = nominal heat transfer rate at 70/20 °C.
• Cooling: Q = QN * ((tW - tA) / 17)^m, where m = 1, tW = mean cooling water temperature, tA = mean air temperature, QN = nominal heat transfer rate at 9/26 °C.

Heat Transfer Rates

Heat transfer rates (Q) are provided for various unit lengths (900 mm to 2000 mm), water temperatures (50 °C to 90 °C for heating; 9 °C to 16 °C for cooling), and mean air temperatures (15 °C to 27 °C). The data is categorized by fan speed settings: minimum, medium, and maximum speed.

For heating, outputs increase with higher water temperatures, longer unit lengths, and higher fan speeds. For example, at 2000 mm length, 90 °C water temperature, and maximum fan speed, heating output reaches up to approximately 9.8 kW at 15 °C air temperature.

For cooling, outputs similarly increase with lower water temperatures, longer unit lengths, and higher fan speeds. Cooling outputs range from around 600 W to over 2.2 kW depending on conditions.

Installation and Connection Details

The convector includes connection fittings and flexible hoses (3/8") for easy installation. The condensate outlet is integrated to manage condensation effectively during cooling operation.

Summary of Best Practices and Recommendations

• Use the 2-pipe connection to maximize heating and cooling efficiency.
• Consider fan speed settings to adjust air flow and heat transfer rates according to room requirements.
• Ensure proper installation of condensate outlet to prevent water accumulation.
• Utilize the temperature equations provided to calculate expected heating or cooling output under varying operating conditions.
