Eco Cute "unimo A/W" Unimo A/W is a high efficiency heat pump hot water unit using natural refrigerant CO2. unimo's ecological footprint is minimal compared to a combustion boiler type hot water unit, the cost of generating hot water is one third, saving energy and reducing CO2 emissions to almost half. This versatile unit has various commercial and industrial applications with its built-in control system operating the hot water storage, heat retention and hot water supply to achieve high efficiency across various operating conditions and throughout the year. Eco Cute "unimo W/W" Unimo W/W uses water as its heat source (including waste hot water) to generate hot water and cold water simultaneously. This industrial heat pump achieves remarkable energy savings by combining simultaneous heating and cooling from one unit boasting a combined COP of 8. This performance is achieved using the transcritical cycle of its refrigerant CO2, providing hot water outlet temperatures of up to 90℃.

For example, a heat source water temperature of 22℃ results in a capacity of 26 ton (90℃). This makes unimo W/W ideal for applications that require both heating (high quality hot water) and cooling on a constant basis such as food processing facilities, resorts and hotels. COP is the coefficient of performance Adsorption Heat Pump AdRef-Noa AdrefNoa can produce chilled water at 5℃ to 15℃ using waste water at 60℃ to 80℃. This unit is ideal for renewable energy, waste energy and biomass energy applications and contributes to environmental sustainability through reducedCO2 emissions. Using water as the refrigerant, this next generation chiller boasts a system COP of 10 with extremely low absorbed power. NH3 Heat Pump Plus+HEAT Plus+HEAT can produce hot water up to 85℃ from various heat sources such as condensed waste heat from compressors, waste heat in factories, river water and lakes. Vapor Recompression (VRC) System This energy-saving system remarkably reduces boiler steam consumption by recovering steam from rectifiers in breweries and vapor from rectifier tanks in distilleries as low pressure steam, increasing that pressure, and providing it as heating steam to kettle and the bottom of rectifier tanks.

Through the use of variable speed components, the supplied capacity can be reduced to match the required load and hence reduce unnecessary energy consumption.

However, for fan coil units, difficulties can arise when optimizing fan and pump speeds at part load. Practically locating optimal water and air flow rates from readily available information and for varying supplied capacities is necessary, in order to reduce the fan coil power consumption. This research attempts to identify whether optimal fan and pump speeds exist for a fan coil unit and how they can be implemented, in a practical manner, in a system control applications. Using an empirical fan coil and pump model, the total power consumption (fan and pump) for different combinations of fan and pump speeds over a range of capacities was calculated. It was observed that, for a given capacity, an optimal combination of fan and pump speeds exists and there was a significant change in power consumption for different combinations of fan and pump speeds supplying the same capacity. A control strategy is described that utilizes a simple fan coil capacity estimation model, coupled with air and water flow rates, along with nominal design data.
