1 + + Heat pump & cooling unit in one The reversible ThermoCooler HP heat pump can be integrated in our Envistar Flex units. All parts of the cooling/heating pump are incorporated in a module section, which is located in the air handling unit. This means that you receive a total solution for heating ventilation air and comfort cooling in one unit. Since everything is integrated in the air handling unit, there is generally no need for frost coils, pump sets or dry coolers. The installation is complete, CE-marked and always test-run in our test facility before delivery. A unit with integrated heating/cooling pump is more energy efficient than a traditional cooling installation with external cooling unit and heating coil. ThermoCooler HP New! Speed controlled scroll compressors with PM motors Electronic expansion valves + Separate module sections that fit through a 900 mm-wide opening to facilitate transportation into the building ThermoCooler HP is the optimal integrated reversible heat pump for Envistar Flex. In some buildings, airflow varies greatly, while requirements are strict for accurate control/regulation of the supply air temperature. ThermoCooler HP meets the requirements through stepless control of the cooling and heating power via a frequency inverter. Airflow m³/s, cooling power kw High EER (COP) up to 6.0 in the cooling application High COP 6 15 in the heating application, depending on outdoor temperature Ideal for large variable air flows, VAV Complete CE-marked cooling and heating installation Envistar 11

Also sufficient in winter -15.3 ºC 22 ºC -20 ºC 20 ºC On a cold winter s day ThermoCooler HP can blow in a supply air temperature of 20 C with a return air temperature of 22 C.

Trim heating as an option If the return air temperature becomes colder than the design temperature, or if there is an imbalance in the air flow, trim heating is available as an option.

2 Also sufficient in winter ºC 22 ºC -20 ºC 20 ºC On a cold winter s day ThermoCooler HP can blow in a supply air temperature of 20 C with a return air temperature of 22 C. ThermoCooler HP together with the rotor can achieve a dry temperature efficiency over 90 % excluding the electricity from the compressor. Trim heating as an option If the return air temperature becomes colder than the design temperature, or if there is an imbalance in the air flow, trim heating is available as an option. The trim heater gets its electricity feed via ThermoCooler HP and can be easily mounted retrospectively if necessary. With design outdoor temperatures under -18 C trim heating is standard. One of the biggest advantages with ThermoCooler HP is that there is no need for pre heater with outdoor temperatures down to around -20 ºC. This assumes a return air temperature of at least 22 ºC. When it is colder than -22 C we recommend a pre heater that is positioned after the supply air fan. Trim heater + 12 Envistar

3 ThermoCooler HP creates many winners High reliability Long service life Does not need defrosting Low installation and operating costs Requires no outdoor installations Saves floor surface New! Accuracy in every detail When we developed ThermoCooler HP, high reliability, long service life, low operating costs and stepless control of temperature/power were our most important criteria. After a lot of research, calculations, comprehensive field-testing and accurate measurements in our Innovation Center, we have decided to place the heat pump s extract air coil before the rotor. This means there is no risk of the coil freezing. Unnecessary defrosting cycles are avoided, as they affect the supply air temperature. The unit therefore has a very high reliability and long service life. As a natural part of our product development, we consider how products will be used and transported. We have therefore designed ThermoCooler HP in a separate module section that will fit through an opening of 900 mm. Simple installation As the whole installation for cooling and additional heating for ventilation is integrated in one unit, there is no need for expensive and large pump sets or plumbing. The responsibility for the installation lies with the supplier instead of several different parties. Investment that pays for itself The installation costs for ThermoCooler HP are considerably lower than a traditional installation. Contrary to a traditional installation, ThermoCooler HP does not require external cooling and heating installations connected to the air handling unit. This can often save more than 30 % of the installation costs. The energy use and operating costs for ThermoCooler HP are considerably lower than a traditional installation. 20% lower energy use Envistar 13

is no need for an outdoor cooling medium cooler or liquid cooler.

The EcoCooler cooling unit or the reversible ThermoCooler HP free up space on the roof creating a fifth facade.

4 No expensive outdoor cooling installations needed Create options for a fifth facade! New installation approach with EcoCooler & ThermoCooler HP As EcoCooler and ThermoCooler HP are integrated in the air handling unit, there is no need for an outdoor cooling medium cooler or liquid cooler. In many places there is a lack of both land and building space, which means higher prices. The EcoCooler cooling unit or the reversible ThermoCooler HP free up space on the roof creating a fifth facade. The roof surface can be used as a pleasant terrace with endless possibilities. The property becomes more attractive, space is freed up, the value increases and the rental income increases. Did you know that... operating costs for the EcoCooler or ThermoCooler HP to cool a 300 m 2 office building are only around 160 a year? 14 Envistar
