High performance heat recovery ventilation units with single-decker slim design to minimise installation space required.
Swap stale air for fresh and save on heating. The Lossnay Fresh Air Energy Recovery Systems set a new standard in ventilation by recovering heat from the air inside your home or office and transferring it to fresh, dry air introduced from outside. Not only providing energy recovery savings in winter by warming the cold fresh air to an acceptable level but also providing the same excellent energy efficiency in summer. Lossnay heat exchangers have an efficiency of approximately 82% thereby eliminating the need for additional electric elements. The Ventilation System for Enhanced Air Quality which provides Free Heating or Cooling.
Simple and Effective. Excellent air quality and unbeatable Heat Exchange Efficiency.
Poor air quality can be attributed to many problems arising in the workplace or the home. It is believed to contribute to a significant loss in productivity, low morale and higher rates of sickness among many employees. The object of providing good ventilation alongside air condition in residential and commercial buildings is to provide conditions under which people can live and work comfort and safety.
Developed and refined over the past 30 years, the LOSSNAY system has perfected the recovery of waste energy. The units reduce overall energy costs by extracting stale air and then recovering the heating or cooling energy to either warm and cool incoming fresh air. By utilising this energy, the LOSSNAY system can save up to 30% on initial capital costs of heating and cooling plant.
Every building needs a supply of fresh air to keep its inhabitants healthy and comfortable. Outdoor air though is rarely, if ever, the same temperature as that maintained by the building's air conditioning system. In the summer, it is too hot. In the winter, it is too cold. The air conditioner is required to compensate for the intake of the hot or cold air adding to the expense of operating the system. LOSSNAY all but eliminates this problem with original energy-recovery technology that uses the heat of the stale indoor air to be expelled to either heat or cool the incoming fresh air to a temperature much closer to the existing indoor air. This process reduces the load on the air conditioning system without cutting off the supply of vitally necessary fresh air.
The remarkable technology that permits the intake of fresh air with minimal loss to indoor temperature is known as the LOSSNAY Core. The cross-flow, plate-fin structure of the energy-recovery unit along with a specially processed diaphragm keep supply and exhaust air separate, ensuring that only fresh air is introduced into the indoor environment while also allowing for the efficient transfer of heat.
The microscopically small pores of the diaphragm have been made even smaller, decreasing the rate at which water-soluble gases such as ammonia and hydrogen pass through. Further, a new specially processed paper used to make the diaphragm has been developed with high moisture permeability characteristics that aid in the transference of moisture for improved energy exchange efficiency. These developments further improve moisture permeability and effectiveness in shielding unwanted gases, resulting in a lower rate of gas transference and more highly efficient energy transfer.
The secret to the unmatched comfort provided by Lossnay core is the cross-flow, plate-fin structure of the heat-exchange unit. A diaphragm made of a specially processed paper fully separates inducted and exhausted air supplies, ensuring that only fresh air is introduced into the indoor environment.
The superior heat transfer and moisture permeability of the special paper assure highly effective total heat exchange (temperature and humidity) when inducted and exhausted air supplies cross in the Lossnay core.
The operation pattern for each day of the week, ON / OFF and air volume can be set using the weekly timer function (up to eight zones per day). Compared to previous models, much finer operation control contributes to enhanced energy saving operation. With a wider range of air volumes, the Lossnay RVX units enable optimised ventilation not just at different times of the day, but for various days of the week as well, allowing further energy savings.
The LGH-RVXT Series feature four fan speeds, and each speed has a range setting of 25%, 50%, 75% and 100%, allowing much finer air volume control. When used in combination with the CO2 sensor or timer function, the air volume can be adjusted according to conditions that realize better performance and reduce power consumption.
During the summer season, the Night Purge mode draws cooler outside air into the room at night. This energy conservation mode reduces the load when the air conditioning is started up the next morning.
With previous models, the unit is operated with only one initially set condition. With new models, it is possible to set freely* the night purge operation for the start conditions, air volume, and operation time and flexibly answer to the operating environment requests that vary with each customer.
* Settings can only be made using the PZ-61DR-E
The automatic damper mode automatically provides the correct ventilation for the conditions in the room. The following shows the effect “By-pass” ventilation will have under various conditions.
* When the outdoor air temperature drops lower than 8°C it changes to the heat exchange ventilation. (Display of the remote controller does not change.)
* In the case of “By-pass” ventilation, the supply air temperature slightly rises more than the outside air temperature because of the heat effect around the ducts or the unit motors
