Problems solved by technology

[0005] In the prior art, several attempts have been made to install sound insulation to avoid noise transmission from the compressor to the outside of the heat source unit, and / or to install vibration damping mechanisms to avoid vibration transmission from the compressor to other components inside the heat source unit, which may also cause noise generation

Embodiment Construction

[0048] Embodiments will now be described with reference to the drawings. It will be apparent to those skilled in the art of heat pumps from this disclosure that the following description of the embodiments is provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims.

[0049] In the drawings, the compressor housing is shown in transparent form in some figures, so that the components housed in the compressor housing are visible. Components inside the compressor housing are shown with dashed lines.

[0050] figure 1 A perspective view of a heat source unit 10 (in the illustrated embodiment, an outdoor unit) of a split-type heat pump is shown. The heat pump includes a refrigerant circuit comprising at least: a heat source heat exchanger 11; a compressor 12; a heat consumption heat exchanger (not shown) such as an indoor heat exchanger; and an expansion valve connected by a refrigerant pipe (Invisible).

Abstract

A heat source unit (10) for a heat pump having a refrigerant circuit, and the heat source unit comprises: an outer casing (13) comprising a bottom plate (14); and a compressor assembly accommodated in the outer casing (13). The compressor assembly (20) comprises a compressor (12) of the refrigerant circuit of the heat pump including a compressor housing (21), a support plate (23) supporting the compressor (12), the support plate (23) being mounted via dampers (43) to the bottom plate (14), and a compressor casing (30) enclosing the compressor (12) and the compressor housing (21), wherein a damping mechanism (25) is arranged between the compressor (12) and the support plate (23), and the compressor casing (30) is fixed to the support plate (23) out of contact with the compressor housing (21).

Description

technical field [0001] The present disclosure relates to heat pumps for cooling and / or heating purposes. Specifically, the present disclosure relates to a split heat pump comprising a heat source unit and at least one heat consumer unit. Background technique [0002] The heat source unit of the heat pump includes an external case that accommodates a part of the refrigerant circuit including the compressor of the heat pump. Speaking of air heat pumps that use air as a heat source, the heat source unit is mainly installed outside the building, and is often also called an outdoor unit. However, in some applications the heat source unit is also arranged inside the building. This applies both to air-to-air heat pumps and to heat pumps that use different heat sources such as floor heat pumps. [0003] As an outdoor unit, the heat source unit was mainly arranged in a hidden place such as the roof of a building in the past, but now the outdoor unit is often installed in front of ...
