Larger capacity Heat Pumps
	Large Heat Pumps from OCHSNER are used today for heating and cooling condominiums, hotels, office buildings, schools and leisure facilities and for recovery of waste heat in industrial processes.

Through savings energy and operating cost, the use of large heat pumps is particularly economical compared to conventional heating or cooling systems and contributes dramatically to a reduction in pollution.
 

Technical advantages

Because of the variety of applications the details are quoted for each application. However the following description generally applies:  

Heat pumps in industrial design are equipped with semihermetic scew compressors of highest quality. Scoll and rotary screw compressors have no reciprocating parts and have thereby smooth operation.   The rotary screw compressors used by OCHSNER have been developed for use in refrigeration technology and have special screw profiles for the highest efficiencies. A special stepless control is used: Over a control piston the load on the screws is varied steplessly and adapted to the capacity required.

Tube and shell evaporators and condensers are normally used with water to water and brine to water heat pumps. The heat exchangers are mounted on sturdy frames on the units. A sound reducing housing can be provided on request .
 

Refrigerant as Working Liquid

OCHSNER use only non-flammable safety refrigerants like R 134a or R 407C  which are chlorine free and have no Ozone Depletion Potential ( ODP of zero) The selection depends among other things on the desired temperature rise and/or the condensation temperature (temperature level of the use of Heat Pump). Heat Pumps with these refrigerants can be installed at almost any indoor location.  

Controls

Control is provided to meet the respective requirements. The microprocessor keeps the selected temperature of the condenser or the evaporator water connection constant or delivers the required flow temperature rate according to outside air temperature. All safety controls are provided to protect the units from overheating or freezing, false rotation, electric motor protection, gear and others.
