If the cooking room and refrigerator are connected in the ceiling space, warm, humid air from the cooking room can come into contact with the cold ceiling area, fixtures, and wiring on the refrigerator side, leading to condensation. Additionally, if condensation in the ceiling space is left unattended, the ceiling may absorb the fallen condensation, resulting in stains or mold on the ceiling. The ceiling-mounted dehumidifier/RFB500G-T is a dehumidifier that is suspended and fixed in the ceiling space, removing moisture that causes condensation, mold, unpleasant odors, stains, and rust. Despite its lightweight and compact design of 34 kg, it boasts one of the industry's top dehumidification capacities. Furthermore, it allows for ON/OFF operation of the dehumidification process via remote control. The ceiling-mounted dehumidifier/RFB500G-T addresses moisture issues in the ceiling space.

The non-fluorocarbon inverter chiller RKE1500C-VRA adopts the new refrigerant HFO-1234yf, reducing environmental impact and user burden. HFO-1234yf is not subject to inspection obligations or recovery obligations upon disposal under the Fluorocarbon Emission Control Law, allowing for significant reductions in management and disposal costs that were burdensome with conventional fluorocarbon refrigerants. Additionally, the ozone depletion potential (ODP) is zero, and the global warming potential (GWP) is less than 1, significantly reduced compared to conventional R32 and R410A, making it environmentally friendly. (As of June 2022) In terms of energy efficiency, the inverter controls the rotation speeds of the compressor, fan, and pump for refrigeration, enabling operation with the minimum necessary power. This contributes to reductions in CO2 emissions and running costs by decreasing power consumption in response to changes in load rates. *There is also the RKE-C-VRB series that uses refrigerant R513A.

【Chiller equipped with TESC】 The power consumption ratio changes with the variation in load rate. The RKE2200C-V, equipped with TESC, can further reduce power consumption compared to conventional models. 【Enables wall-mounted installation and space-saving setup】 Compared to conventional models, the product installation area has been reduced by 36%. Additionally, it allows for intake and exhaust, piping, and wiring connections from the sides, enabling wall-mounted installation. 【Significantly reduces environmental impact by adopting refrigerant R32】 Contributes to achieving carbon neutrality. When compared to conventional models filled with R410A, it can reduce CO² emissions (equivalent value) by approximately 70%.

The Free Cooling Module Chiller/Eco Hybrid FCMC55A is an energy-saving chiller that integrates a fan cooler for natural cooling and a modular chiller. By utilizing the temperature difference between the return water temperature to the chiller and the outside air temperature, the fan cooler enables natural cooling, which suppresses the operation of the DC inverter chiller. When natural cooling is insufficient, appropriate chiller operation is performed depending on the situation. Particularly in winter, when the temperature difference between the outside air temperature and the return water temperature increases, it is possible to significantly reduce power consumption. Additionally, with the modular controller (sold separately and required), backup operation can automatically start if a malfunction occurs in some modules, and operation can be controlled based on the load, allowing for operation with a variable number of units. Rotation operation can also be implemented to equalize the operating hours of each module, contributing to the overall longevity of the system.

■Maximizing the use of natural energy to achieve significant energy savings. In winter, cooling is performed solely through free cooling due to low outdoor temperatures. During the transitional period when outdoor temperatures are similar to the outlet water temperature of the eco-hybrid, cooling is primarily done through free cooling, and if the cooling capacity of free cooling is insufficient, a chiller will supplement the cooling. By actively utilizing free cooling, power consumption can be reduced, leading to energy savings. ■As a modular chiller, it can be installed in a maximum of 10 units (150HP). By adopting a pressure equalization pipe structure in the water tank, it has become possible to install multiple units (pressure equalization pipes are required for on-site installation. Please consult us for details). Even if the customer's load increases, it can be expanded in increments of 37kW*. Expansion can be done at minimal cost* based on rated cooling capacity. ■Expanded operating temperature range from -20 to 45℃. By adopting a brine indirect cooling method for cooling through free cooling, it can now be used in colder regions. ■Liquid temperature setting range is 5 to 35℃. It can be used for a wide range of applications. ■Adoption of cationic electrophoretic painting. The heat exchangers for the fan cooler are treated with cationic electrophoretic painting to improve corrosion resistance. The exterior is powder-coated to enhance corrosion resistance.
