Main components 3 1 2 4 The anfoss heat pump consists of one cabinet containing the following main parts: 1 ompressor Scroll compressor 2 irculation pumps ondensor circulation rine circulation 3 Heat exchanger ondensor vaporator e-superheater 4 lectrical cabinet and control panel ntire control equipment Logical menu system Graphic display The control equipment checks the heat pump s components and ensures starting and stopping of the pump as well as checking that the pump produces heat, cooling or hot water. 2 VM2
Space requirements mm mm mm mm mm mm mm 6 mm mm To facilitate the installation and subsequent testing and maintenance there must be sufficient free space around the heat pump. The figure to the left shows how an installation with several heat pumps is set up in groups of two and two in order to facilitate access to the pumps. mm mm 16 Minimum headroom for raising the heat pump.

Tolerances in the measuring methods can also cause variations. 1) t W3 according to N1411. (including circulation pumps). 2) t W4 according to N1411. (including circulation pumps). 3) Nominal flow: heating circuit ΔK, cooling circuit Δ3K. 4) nti-freeze in cooling circuit: thanol-water. ) t nominal flow. 6) Sound power level measured according to N ISO 3741 at OW4 (N 122). 7) The values apply to a new heat pump with clean heat exchangers. 8) It is important to note that not all cooling circuit temperatures and heating circuit temperatures can be combined.
