We can offer units from 7 to 50 kw capacity in heating and from 7.5 to 54 kw capacity in cooling modes. The heat pump is controlled by a microprocessor that controls supply air parameters and ensures efficient energy use. The refrigeration system of the heat pump includes a variable capacity scroll compressor that enables precise temperature control and efficient energy use. For best heat transfer u-l evaporators and condensers are used. In all heat pumps, the R410 refrigerant, which has a zero ozone depletion potential, is used. controlled 4-way valve automatically switches between cooling and heating modes. The construction of the heat pump enables to do a defrost cycle by not turning the unit off. efrost cycles are controlled by a microprocessor, that ensure defrost cycle start on demand. omponents used in the units ensure safe and efficient work of the heat pumps. E Fans Highly efficient in all operating areas, E motors are available in all types of Verso units and correspond to the IE3 premium efficiency level. High efficiency is determined by low energy consumption, high efficiency factor and the best values of the SFP factor. y using E fans in Verso units the following advantages are achieved: Extremely high efficiency up to 92% Valuable energy saving up to 30% comparing with Integrated motor controller, no need for a frequency converter Very smooth and silent operation Long-life E fans inside MLV U reserves the right to introduce changes of parameters and sizes in the process of improvement of the air handling units. 5

8 esign Heat Exchangers Verso air handling units may generate different energy efficiency levels with four main types of heat exchangers. The most advanced one is a rotary heat exchanger with the thermal efficiency of 84% and the minimum risk of freezing. counter cross-flow plate heat exchanger and a double plate heat exchanger are also highly effective and may have efficiency coefficients up to 92% or 82% correspondingly, however, they are very sensitive to low outdoor temperatures. standard plate heat exchanger complete the range of the heat exchangers with the maximum efficiency of 70%. luminium is used as a material for the exchangers. nti-frost precautions Under conditions when the outdoor air temperature is low and humidity is high, the risk of heat exchanger frosting may appear. epending on the type of recovery, different methods of anti-frost protection are available: cold air by-passing, or/and supply air fan speed reducing. For an extremely low outdoor air temperature the duct mounted electric preheater is recommended. The counter crossflow heat exchanger is even more sensitive for low outside air temperatures, as the risk of frosting appears in the temperature range from 0 to -5 and below. standard aluminium cross-flow plate heat exchanger has better features, as the risk of freezing appears only at -10. The lowest risk and the highest resistance to cold outside air is a competitive feature of the rotary heat exchanger, as it does not freeze even at the temperatures of -30 if the humidity level of the air is appropriate. Fans In VERSO series units plug type fans are used, therefore, units are silent and use electricity effectively. The fans are balanced statically and dynamically, based on the ISO 1940 standard; therefore, unit vibration is minimal and meets all requirements. While running, fans exhibit the following qualities: Very high efficiency coefficient. Frequency converters ensure an optimal capacity. Good acoustic performance. Longevity: a fan is directly connected to the electric motor; therefore, there is no a belt gear that simplifies maintenance. There is a possibility to install an air flow measuring device. Fans are equipped with three-phase 400 V motors and are controlled with a frequency converter. Safety category IP55 according to IE Windings insulation category F. Maximum operating temperature is 40. Fans are made of aluminium, steel or high performance composite materials painted in blue RL new design of the impeller can reach up to 73% of efficiency. n aluminium or high performance composite impeller has less weight and vibration force on motor bearings. 8 MLV U reserves the right to introduce changes of parameters and sizes in the process of improvement of the air handling units.

Noise Reduction Sections To avoid excessive pressure losses inside the air handling unit, duct mounted sound attenuation sections are offered for VERSO units. The sound attenuation section of 900 mm length will reduce the noise to air ducts by 15 to 20 d, a longer section of 1,200 mm in length by 20 to 25 d. The width and height of these sections correspond to air handling unit dimensions. The baffler-type sound absorber is installed inside this section. afflers are filled with special acoustic mineral stone wool and are covered by non-woven glass fibre felt certified to be inside the air duct. Mineral wool can be replaced with polyester wool in the case of a special request.
