Page 23 4.2 Checking hot circuit 1. Check that condensers and subcoolers are correctly connected. Make sure that the flow direction is correct. Use the latest PI or flow diagram for reference. 2. Make sure that all transmitters in the hot water system are installed and connected. 3.
Page 24 4.4 Checking refrigerant circuit 1. Make sure that nothing was damaged or loosened during transport. 2. Check screws and flange connections. 3. Check oil and refrigerant levels and make sure that there are no leaking connections. Use an electronic sniffer, but note that they usually react on all kinds of chemicals.

Page 28 4.10 Setting up distribution condenser/subcooler 1. Start the circulation and open up all throttling valves to the fully open position. If the circuit is capacity controlled, make sure the system is running at the maximum flow. 2. Measure the individual flows and compare to the specified flows. Measured total flow: m3/h or kg/s If the flow notably deviates from the specified flow, search for the reason for this deviation.
Page 29 Subcooler, optional One of the underlying ideas in the design of the Oilon ChillHeat product family has been to use a single machine both for cooling and heating. All ChillHeat products are well suited for heating and cooling applications, either as dedicated cooling or heating solutions or as a combined solution.
Page 30 It is possible to connect several ChillHeat heat pumps connected in series for an even higher capacity heating or cooling solution. Automation is an important feature in all ChillHeat products. A versatile automation system enables energy-efficient and easy ChillHeat operation. 5.2 Operating principle GSHP19 ver.
Page 31 The high-pressure gaseous refrigerant is led into the condenser, where it releases its heat energy into the water that circulates between the ChillHeat pump and the heat sink. As the refrigerant releases its heat energy and its temperature drops, it condenses to liquid form again.
Page 32 In this example, water is cooled down to 7 °C, and the energy taken from the water is used to heat up heating network water to 60 °C. Collecting heat The Oilon ChillHeat heat pumps can use various heat sources for collecting heat, for example: ● recovered waste heat at refrigeration plants to generate hot water, thereby substituting valuable primary energy ●...
Page 33 5.4 Coefficient of performance Heat pump efficiency ratios are measured by the coefficient of performance (COP) and cooling coefficient of performance (COPc) values. COP indicates the amount of heat energy produced by the heat pump divided by the energy consumed by the heat pump. COP depends largely on heat source and heating network temperatures.
