1 Mini Heat Pump Monobloc System 1.1 System Schematic Figure 1-1.1: System schematic Fan Coil Units Floor Heating ‘3Way Valve Mini Heat Pump Monobloc Collector By-pass Valve Distributor Cold Water Inlet DHWTank Mini Heat Pump Monobloc is an integrated air-to-water space heating, space cooling and domestic hot water heat pump system. The outdoor heat pump system extracts heat from the outdoor air and transfers this heat through refrigerant piping to the plate heat exchanger in the hydronic system.
1.2 System Configurations Mini Heat Pump Monobloc can be configured to run with the electric heater either enabled or disabled and can also be used in conjunction with an auxiliary heat source such as a boiler. The chosen configuration affects the size of heat pump that is required. Three typical configurations are described below. Refer to Figure 1-1.2. Configuration 1: Heat pump only The heat pump covers the required capacity and no extra heating capacity is necessary.

4 System and Design Unit Selection 4.
4.2 Mini Heat Pump Leaving Water Temperature (LWT) Selection The recommended design LTW ranges for different types of heat emitter are: For floor heating: 30 to 35°C For fan coil units: 30 to 45°C For low temperature radiators: 40 to 50°C 4.
5 Typical Applications 5.1 Space Heating Only The room thermostat is used as a switch. When there is a heating request from the room thermostat, the Mini HP unit operates to achieve the target water temperature set on the user interface. When the room temperature reaches the thermostat’s set temperature, the unit stops. Figure 1-5.
5.2 Space Heating and Domestic Hot Water The room thermostats are not connected to the Mini HP unit but to a motorized valve. Each room’s temperature is regulated by the motorized valve on its water circuit. Domestic hot water is supplied from the domestic hot water tank connected to the Mini HP unit. A bypass valve is required. Figure 1-5.
5.3 Space Heating, Space Cooling and Domestic Hot Water Floor heating loops and fan coil units are used for space heating and fan coil units are used for space cooling. Domestic hot water is supplied from the domestic hot water tank connected to the Mini HP unit. The unit switches to heating or cooling mode according to the temperature detected by the room thermostat. In space cooling mode, the 2-way valve is closed to prevent cold water entering the floor heating loops. Figure 1-5.
5.4 Space Heating and Space Cooling Floor heating loops and fan coil units are used for space heating and fan coil units are used for space cooling. The room thermostats are not connected to the Mini HP unit but are connected to the fan coil units. Figure 1-5.
5.5 Space Heating and Domestic Hot Water (Bivalent) 5.5.1 Auxiliary heat source provides space heating only Figure 1-5.
5.5.2 Auxiliary heat source provides space heating and domestic hot water Figure 1-5.
5.5.3 Auxiliary heat source provides additional heating If the Mini HP unit’s outlet temperature is too low, the auxiliary heat source provides additional heating to raise the water temperature to the set temperature. An additional 3-way valve is required. When the Mini HP unit’s outlet temperature is too low, the 3-way valve is open and the water flows through the auxiliary heat source. When the Mini HP unit’s outlet temperature is high enough, the 3-way valve is closed. Figure 1-5.
5.6 Space Heating Through Floor Heating Loops and Fan Coil Units Dual setpoint function application with or without two thermostat connect to the outdoor unit. The floor heating loops and fan coil units require different operating water temperatures. To achieve these two set points, a mixing station is required. Room thermostats for each zone are optional. Figure 1-5.
5.7 Space Heating and Domestic Hot Water Heating with a solar energy kit Space heating application and domestic hot water heating with a solar energy kit connected to the system; space heating provided by heat pump, domestic hot water heating is provided by heat pump and solar energy kit.

1 Preface to Part 3 1.1 Notes for Installers Boxes The information contained in this Engineering Data Book may primarily be of use during the system design stage of a Mini Heat Pump Monobloc project. Additional important information which may primarily be of use during field installation has been placed in boxes, such as the example below, titled “Notes for installers”.
2 Installation 2.1 Acceptance and Unpacking Notes for installers When units are delivered check whether any damage occurred during shipment. If there is damage to the surface or outside of a unit, submit a written report to the shipping company. Check that the model, specifications and quantity of the units delivered are as ordered. Check that all accessories ordered have been included. Retain the Owner’s Manual for future reference. 2.
2.3 Placement Considerations Placement of the outdoor unit should take account of the following considerations: Outdoor units should not be exposed to direct radiation from a high-temperature heat source. Outdoor units should not be installed in positions where dust or dirt may affect heat exchangers. Outdoor units should not be installed in locations where exposure to oil or to corrosive or harmful gases, such as acidic or alkaline gases, may occur.
2.5 Cold Climate Installation In cold climate locations installation should take account of the following considerations: Never install the unit at a site where the suction side may be exposed directly to wind. To prevent exposure to wind, install a baffle plate on the air discharge side of the unit. To prevent exposure to wind, install the unit with its suction side facing the wall. In areas of heavy snowfall, a canopy should be installed to prevent snow entering the unit.
2.8 Drainage Drainage ditch should be provided to allow drainage of condensate that may form on the air side heat exchanger when the unit is running in heating mode or domestic hot water mode. The drainage should ensure that condensate is directed away from roadways and footpaths, especially in locations where the climate is such that condensate may freeze. Figure 3-2.6: 5/7/9kW models drainage hole Drain hole Thisdrain holeiscovered by rubber plug.

3 Water Pipework 3.1 Water Circuit Checks Mini Heat Pump Monobloc units are equipped with a water inl et and outlet for connection to a water circuit. Mini Heat Pump Monobloc units should only be connected to closed water circuits. Connection to an open water circuit would lead to excessive corrosion of the water piping. Only materials complying with all applicable legislation should be used. Before continuing installation of the unit, check the following: The maximum water pressure ≤ 3 bar.
To determine the maximum allowed water volume in the entire circuit, proceed as follows: Determine the calculated pre-pressure (Pg) for the corresponding maximum water volume using the Figure 3-3.1. Figure 3-3.1: Maximum water volume 2.8 A1: S ystem without glycol for 1-phase 12~16kW and 3-phase 12~16kW unit A2: System without glycol for the 5/7/9kW unit Pressure (bar) 2.3 1.8 1.3 A1 A2 0.8 0.
When using non-copper metallic piping, be sure to insulate the two kind of materials from each other to prevent galvanic corrosion. For copper is a soft material, use appropriate tools for connecting the water circuit. Inappropriate tools will cause damage to the pipes 3.4 Water Circuit Anti-freeze Protection Ice formation can cause damage to the hydronic system. As the outdoor unit may be exposed to sub-zero temperatures, care must be taken to prevent freezing of the system.
That in case of an installation with a domestic hot water tank, only the use of propylene glycol is allowed. In other installations the use of ethylene glycol is fine.
4 Electrical Wiring 4.1 General Notes for installers Caution All installation and wiring must be carried out by competent and suitably qualified, certified and accredited professionals and in accordance with all applicable legislation. Electrical systems should be grounded in accordance with all applicable legislation. Overcurrent circuit breakers and residual-current circuit breakers (ground fault circuit interrupters) should be used in accordance with all applicable legislation.
Make sure no external pressure is applied to the terminal connectors. When installing the ground fault circuit interrupter make sure that it is compatible with the inverter (resistant to high frequency electrical noise) to avoid unnecessary opening of the ground fault circuit interrupter This unit is equipped with an inverter. Installing a phase advancing capacitor not only reduce the power factor improvement effect, but also may cause abnormal heating of the capacitor due to high frequency waves.
