  • Page 8: Introduction

    Introduction Operating principles of the air / water heat pump 1 Introduction 1.1 Operating principles of the air / water heat pump For comfortable living to be achieved, room temperatures should be slightly above 20 °C. This temperature deviates only slightly from the outside temperature during most of the year.

  • Page 9: Coefficient Of Performance And Performance Factor

    Introduction Coefficient of Performance and performance factor Ambient heat is brought up to a higher temperature level in a cyclical process. To do this, an environmentally compatible refrigerant undergoes four steps: • The refrigerant boils inside the evaporator where it is transformed from a liquid into the gas state.

  • Page 10: Economical And Environmentally Friendly

    Introduction Economical and environmentally friendly Example Coefficient of performance = 5.08 (A7 / W35) For an outside temperature of 7 °C the air / water heat pump produces hot water at 35 °C at a COP of 5.08. Thus, 5.08 kilowatt-hours of heat energy can be generated from one kilowatt-hour of electrical energy.
  • Page 11 Microgeneration Certification Scheme (MCS) – www.microgenerationcertification.org Note Panasonic offers a free program for sizing heat pumps with which the seasonal performance factor can be calculated according to VDI 4650, the Aquarea Designer (see the “Panasonic Aquarea Designer” section in the planning chapter).

Depending on the nominal heating capacity and the capacity of the additional electric heater, individual models differ in the number of mains connections.

  • Page 95: Hydraulic Decoupling For Standard Pumps And High-Efficiency Pumps

    Automatic mixers or thermostatic valves can restrict the hot water circu- lation to such an extent that the flow falls below the minimum circulation. To prevent this, Panasonic recommends always combining heat transfer systems without hydraulic decoupling with an auto-bypass valve between the heating supply flow and return flow.

  • Page 96: Inline/Strainer Filter

    Project Design Hydraulics Hydraulic integration Both types of control reduce the pump speed when the differential pressure or resistance in the heating circuit increases. As a result, the volume cir- culation decreases to a far greater extent than with unregulated standard pumps, and can cause the volume flow to drop below the minimum (see technical data) and thus to a fault.

    Project Design Hydraulics Pumping height and pipe network resistance 5.13.2 Pumping height The device-internal water circulation pump of Aquarea heat pumps differs and pipe network in delivery height and delivery volume according to the series and model resistance version. In addition, there are distinctions between standard pumps, high- efficiency pumps without differential pressure control and high-efficiency pumps with differential pressure control (see also unit overview at the start of the document and the technical data).
  • Page 98 Project Design Hydraulics Pumping height and pipe network resistance Tipp 2: Note the rated pipe diameter The pressure drop in the pipelines increases exponentially with the volume circulation. That means that doubling the rate of circulation increases the pressure drop by a factor of 4! This is due to the circulation speed in the pipe, which depends on the rate of circulation and the internal pipe diameter.
