1 Air-conditioning and climate-control technology We create a good indoor climate.

2 IS A GOOD CLIMATE A LUXURY? Most people spend a large part of their lives in closed rooms. Where this is the case, outside air is locked out together with the inclement weather. Air conditioning is therefore installed where many people share a limited volume of air. For good reasons, because good room climate conditions are not a luxury but an essential fact of life, indispensable for performance and well-being. What are the characteristics of a good room climate? First of all a pleasant temperature to avoid sweating or shivering, but that alone is not enough! Most people are not aware of how important the right humidity of the air is for people. Excessively dry air irritates the mucous membranes. High humidity gives an oppressive feeling, even if the temperature is right. Apart from the condition of the air, its quality also plays an important role. For example, unpleasant smells and noxious substances (such as smoke and CO 2 ) may be present in any building. The only solution is to supply an appropriate proportion of fresh air to the rooms in order to reduce the concentrations to an acceptable level. Numerous requirements one solution Naturally, demands on air conditioning are as individual as a person s other needs. The building surroundings also play an important role. Menerga provides air conditioning system solutions for nearly every sector, whether for swimming pool halls, comfort units for private houses or industrial and commercial premises. A typical feature of all Menerga systems is the synergetic combination of long-established, partly forgotten energy-saving technologies with innovative developments pointing the way to the future for this entire business sector. The very best energy recycling This method of regenerative heat recovery in air conditioning units yields considerable advantages. Above all, a high temperature efficiency of more than 90 %. Heat recovery from return air, for example in department stores, banks and other high traffic buildings with high internal heat loads, often makes reheating of outside air unnecessary. Furthermore, with Resolair comfort air conditioning units cooling recovery is possible and some of the indoor air humidity can also be recovered a further plus point for comfort. Menerga fields of application: Museums / galeries Low-energy buildings Theaters Historical buildings Sports grounds Public swimming pool halls Private swimming pool halls Hotels / restaurants Schools / universities Hospitals Shopping centers Offices / commercial buildings Banks Industry Data centers 2 Heat recovery Heating Cooling Moisture recovery Free cooling Control and adjustment

3 Comfort air conditioning for industrial and commercial buildings as well There are units in the Resolair family that have been developed especially for utilisation in industrial and commercial premises and so all the advantages of regenerative heat recovery are also available for this important sector of air conditioning. Further advantages: in most cases major reconstruction is not required even for refurbishment. Installation can be carried out while production is running. The units can even handle large air volumes and require minimal space for installation. For a good partnership Whether for planners, architects, plumbers, plant operators or owners our full expertise is available to all customers. Our experience of more than 30 years and several smart utilities from our own development, such as the h,x-diagram (psychrometric chart) software or our configuration design programs, help you manage your daily tasks. Our service team will continue to support you with advice and active solutions even after installation is complete. Quality provides the basis Quality is as important to us as to our customers. The supply of equipment that operates without fault and can be optimally adjusted is a matter of course for us. You may assure yourself of our quality even before delivery, being our guest during factory trial runs. BENEFITS Temperature efficiency of more than 90 % Based on its high degree of efficiency the Resolair can also be used in the summer as a cooling recovery system The entire cross-section of the unit is utilised, therefore low reciprocal loss of head and compact design of the unit High cost advantage in the operating costs Immediately operational installations, factory trial run La Suisse Assurances in Lausanne, Switzerland IT center Passau University, Germany 3

Control unit Easy to use input and function buttons permit individual adjustments. Supplemented with a modem and the Menerga interface, the comfort air conditioning unit can be monitored almost anywhere. Thermal energy accumulators The readily accessible thermal energy accumulators contain high capacity heat storage mass and are easily cleaned. They take up thermal energy very quickly and release it just as quickly to cold air. The temperature efficiency achieved is greater than 90 %. 4

5 That s how it works: Resolair regenerative energy transformer The unit contains two heat packets with highly sensitive accumulator mass, through which the outside and exhaust air are transported alternately. The accumulator mass is able to capture heat from a warm air flow very rapidly and redeliver this just as rapidly to a cold air flow. Due to the constant exchange of outside air and exhaust air in the accumulators, there is a high recovery of humidity. Cycle 1 In cycle 1 the motor-driven flap system channels the return air via accumulator 1 and heats this up. At the same time cold outside air flows through accumulator 2, in which it is heated up together with the heat stored in the previous cycle. Cycle 2 In cycle 2 the outside air is heated up using the heat stored in accumulator 1. The return air then heats up the cooled accumulator 2 and prepares the next cycle. Cycle 1 Cycle 2 For the removal of higher internal heat loads at high outside air temperatures the integrated compression refrigerating machine is switched on for series 66 and 68. return air, outside air, supply air, exhaust air Resolair units from series 65 are specifically used in industrial and commercial buildings. For this type of unit the motor-driven flap system is located in the center of the unit. The air flow is channelled through the flap system in 2 cycles. As a result of the alternating admission of the heat packets, the heat of the return air is almost completely transferred to the cold outside air. 5
