LUKO Ceiling-Mounted System

Dehumidification is crucial for maintaining a healthy and comfortable environment, effectively suppressing allergens and protecting indoor structures and equipment. The importance of dehumidification is highlighted below:Reduce the growth of mold and dust mites: Dust mites need a relative humidity of 65% or higher to reproduce. Using a dehumidifier can maintain the humidity at an ideal level, inhibiting the growth of mold and dust mites.Improve respiratory health: Humid air increases the burden on breathing, while dehumidified air is drier and helps alleviate symptoms of asthma and COPD (chronic obstructive pulmonary disease).Reduce allergen concentration: Dehumidification can reduce the survival rate of allergens such as pollen and animal dander in the air, thus alleviating allergic reactions.Prevent moisture damage to buildings and furniture: Excessive humidity can cause wood to warp, crack, and metal to rust. Dehumidification can maintain the lifespan of structures and equipment.Regular dehumidification creates a healthier, more comfortable, and more durable indoor environment.

Ceiling-mounted dehumidifiers and air conditioners differ in their operating principles, impact on room temperature, power consumption, drainage methods, and applicable ranges. The following five key points will explain these differences.The operating principles are different: ceiling-mounted dehumidifiers draw in humid air through a fan, condense the moisture through a cooler or adsorbent, and then return the dry air to the room; air conditioners, on the other hand, use the refrigerant to evaporate and absorb heat during the cooling cycle to condense water vapor, then discharge the condensate and send out cool air at the same time.Impact on room temperature: The air discharged by the dehumidifier is slightly warm after heat dissipation, so the room temperature remains basically unchanged and feels slightly warm; the air conditioner cools the air at the same time when dehumidifying, so the air is cooler.Power consumption difference: Dehumidifiers can run for a long time with low power consumption; the dehumidification mode of a regular air conditioner consumes about twice as much power as a dehumidifier.Drainage method: Ceiling-mounted dehumidifiers usually have a built-in water tank or drain pipe and drain pump to automatically drain condensate; air conditioner condensate only flows to the outside through the drain pipe, and users do not need to empty the water tank.Application scope: Ceiling-mounted dehumidifiers can control humidity in multiple rooms simultaneously through a duct system, maintaining a balanced humidity throughout the house; air conditioners, on the other hand, primarily cool large areas, with relatively limited dehumidification capacity and slower dehumidification speed.In summary, if you want uniform, long-lasting, and energy-efficient humidity control throughout the house, a ceiling-mounted dehumidifier is more suitable; if you need to balance rapid cooling and dehumidification and focus on a single large space, you can consider the dehumidification mode of an air conditioner.

The dehumidification effect of an air conditioner is merely a byproduct of the refrigeration process and cannot completely replace a professional dehumidifier, mainly for the following reasons:Insufficient dehumidification: The air conditioner's "independent dehumidification" mode has a relatively small actual dehumidification capacity, and it cannot quickly reduce the indoor relative humidity to the ideal level when encountering a high humidity environment.High power consumption: Air conditioners need to dehumidify through intermittent or continuous cooling, and their power consumption is much higher than that of dehumidifiers with the same dehumidification capacity.The room temperature may be too low or uncomfortable: It dehumidifies and cools down at the same time, which may cause the indoor temperature to be too low when used in spring, autumn or winter, affecting the comfort of the body.Inability to maintain precise humidity: Air conditioners can only achieve dehumidification by controlling the temperature, lacking a constant humidity control function that automatically starts and stops based on the ambient humidity, which can easily lead to over- or under-dehumidification.

Please refer to the following information regarding whether or not ceiling-mounted dehumidifiers are suitable for installation:Suitable installation spaceThe ceiling is either not yet sealed or has removable sections, which facilitates pipe installation and subsequent maintenance.The ceiling clearance should be at least 45 cm to accommodate the machine body, insulation layer, and pipelines.In areas where people spend a lot of time, such as the living room and bedroom, it can both dehumidify and purify the air.Dressing rooms or boutique storage rooms need to be kept humid to protect clothing and collectibles.Unsuitable installation spaceKitchens, bathrooms, and other spaces with strong fumes or odors may spread pollution throughout the house.The ceiling is already paneled or the woodwork is complete, requiring extensive disassembly and reassembly, which is costly.The ceiling height is less than 45 cm, making it impossible to place equipment or hindering maintenance.

Before installation, the ceiling must meet the following structural requirements:The ceiling must be an unpaneled or removable light steel frame structure to allow for the installation of the main unit and maintenance piping.A space of 45–65 cm should be reserved between the floor slab and the ceiling to accommodate the thickness of the equipment, corner pieces, insulation layer, and drainage slope.Leave at least an 80×40 cm maintenance port to ensure that the filter screen, circuit board and control box can be directly replaced.Pipes under beams must be pre-installed or pipe holes must be reserved. Do not wash the beams on site, and ensure that the ductwork is unobstructed.For pre-installing the control panel and humidity sensor wiring in the wall, it is recommended to place them in the center or an open area to obtain average humidity values.

The following are the key points for maintaining the purification function of a ceiling-mounted air purifier/dehumidifier:Clean the pre-filter regularly: Remove it every 2–3 months and wipe off surface dust with a dry cloth or a low-speed vacuum cleaner to avoid affecting the lifespan of the subsequent filters.Replace the HEPA filter: It is recommended to replace it every 12–14 months to maintain the filtration efficiency of PM2.5 and particulate matter.Clean the heat exchanger core and air duct: Use a soft brush or vacuum cleaner to remove accumulated dust every 6 months to avoid obstructing heat exchange and reducing purification efficiency.Check the UV lamps: If equipped, test their operation or replace them annually to maintain sterilization efficiency.Ensure air inlets and outlets and maintenance openings are unobstructed: Regularly check ceiling maintenance openings and air vents for blockages to facilitate subsequent disassembly and maintenance.

Key points of drainage pipe planningDrainage pipes should be located close to the building's wall drain outlets and maintain a 1:100 natural slope (1 cm lower for every 100 cm) to prevent backflow of drainage.By adopting a shared pipe method with the air conditioning drainage pipe tee, the pipeline can be shared and the amount of drilling and construction work can be reduced.Drainage pipes should be laid in a straight line to avoid local back slopes or horizontal water accumulation, ensuring continuous and smooth water flow inside the pipes.If the drainage distance is too long or the height difference is too large, a drainage motor (drain pump) needs to be installed to raise the drainage head and prevent blockage.Key points of duct planningThe minimum bending radius at duct bends should be 1.5 times the duct diameter, and a gentle bend of ≤30° should be used to reduce pressure loss and wind noise.The supply and return air ducts should utilize pre-drilled holes to pass through walls or floors to avoid on-site beam washing or significantly reducing ceiling height.
