Heat pump
A heat pump includes a compressor for compressing refrigerant, which compressor operates within an operating speed range and in so doing causes at least one disturbance frequency of the first order, and the heat pump comprising further heat pump components which are disposed on a support element and through which refrigerant flows as well. A unit composed of the support element and the heat pump components disposed thereon has a first natural frequency which is greater than the disturbance frequency of the first order transmitted by the compressor operating in the operating speed range to the unit acting as a rigid body.
1 . A heat pump comprising
a compressor for compressing refrigerant and operating within an operating speed range to cause at least one disturbance frequency of a first order;
a unit comprising a support element and heat pump components disposed on the support element;
a fluid line between the compressor and the unit;
a housing; and
first and second spring elements;
wherein the compressor is fastened via the first spring element directly to the housing and the support element is fastened by the second spring element directly to the housing;
wherein the support element comprises a plate;
wherein one of the heat pump components disposed on the support element is a refrigerant collector;
wherein the refrigerant flows through the heat pump components;
wherein the at least one disturbance frequency is transmitted by the compressor to the unit;
wherein the unit acts as a rigid body and has a first natural frequency greater than the at least one disturbance frequency; and
wherein the compressor and the unit, apart from the fluid line between the compressor and the unit, are configured to be capable of vibration independently of one another.
2 . The heat pump according to claim 1 , wherein the support element has a first natural frequency which is greater than the at least one disturbance frequency of the first order caused by the compressor operating within the operating speed range.
3 . The heat pump according to claim 1 , wherein each heat pump component has a first natural frequency which is greater than the at least one disturbance frequency of the first order caused by the compressor operating within the operating speed range.
4 . The heat pump according to claim 1 , further comprising a pipework of the heat pump components, wherein the unit, including the pipework of the heat pump components, has a first natural frequency which is greater than the at least one disturbance frequency of the first order transmitted by the compressor operating within the operating speed range to the unit acting as the rigid body.
5 . The heat pump according to claim 1 , wherein each of the first and second spring elements is formed at least partially from an elastomer.
6 . The heat pump according to claim 1 , wherein a center of gravity of the unit is selected such that a weight force is vertically introduced into the second spring element.
7 . The heat pump according to claim 1 , wherein the compressor has an operating speed range of 700 to 7200 revolutions per minute.

10 . The heat pump according to claim 1 , wherein the compressor has an operating speed range of 900 to 6600 revolutions per minute.
11 . The heat pump according to claim 1 , wherein the unit has a first natural frequency of more than 120 Hz.
12 . The heat pump according to claim 1 , wherein the unit has a first natural frequency of more than 140 Hz.
13 . The heat pump according to claim 1 , wherein the plate has at least one bent edge.
14 . The heat pump according to claim 1 , further comprising a load transfer element disposed on a lower face of the housing, wherein the load transfer element comprises a rail.
15 . The heat pump according to claim 1 ,
wherein the heat pump components further comprise a valve device; and
wherein the compressor is situated adjacent to the plate on which the heat pump components including the valve device and the refrigerant collector are mounted.
