Abstract
A refrigerating unit comprising an adiabatic box provided with a door to its opening, a machine compartment in contact with said adiabatic box, and a refrigerating cycle wherein the machine compartment is covered with a damping plate and is attached to the adiabatic box with a jointing means so as to be sealed, and further said refrigerating unit comprises an oil cooler for cooling lubricating oil in a compressor in the refrigerating cycle is provided. By this, noise and vibration generated by a refrigerator itself such as noise generated by a flowing or boiling refrigerant in the compressor and an evaporator can be effectively removed, noise and vibration generated by resonance between vibration by a refrigerator and a wall or a cabinet can be attenuated and the effect of heat release can be enhanced. It is preferable that an outer casing of the adiabatic box is also made of a damping plate or a damping material is stuck to important positions of the outer casing made of an iron plate after forming an iron plate. Noise generated by a flowing or boiling refrigerant in the evaporator can be absorbed in a sound absorbing material layer and can be effectively attenuated by also provid…
