摘要： The invention relates to refrigeration apparatus of the type having a casing which contains an electric motor and reciprocating compressor means. This type of apparatus is subject to creating undesirable vibrations and noises, the reduction of which is the object of the invention. This is done by adding additional mass to the casing which is equal to fifty per cent or more of the mass of the casing. The correspondingly greater mass inertia has the effect of causing the casing to absorb vibrations emanating from the interior of the casing to a lesser extent than before.

摘要： The invention relates to a temperature control system for refrigeration unit. In this system a capillary tube extends between the condenser and the evaporator and a chamber upstream from at least a section of the capillary tube contains a PTC resistor. The PTC resistor is supplied with current in response to a thermostatic sensing of a predetermined low temperature in the room or compartment which contains the evaporator. In response thereto the PTC resistor generates enough heat to produce a vapor plug which throttles of stops the flow of refrigerant in the capillary section but not enough heat to cause coking of the refrigerant oil which would permanently plug the capillary tube. The downstream capillary section is so dimensioned that it is permeable to liquid refrigerant but is substantially impermeable to the refrigerant vapor generated in the chamber.The invention relates to a compressor refrigeration plant comprising a capillary tube between the condenser and evaporator and, associated with the capillary tube, an intermittently operable electric heating resistor.It is known to heat the capillary tube or a conduit section immediately upstream thereof by means of an electric heating resistor, to evaporate the refrigerant that is there located and in this way to produce a vapour plug which is practically impossible to discharge through the capillary tube. With the aid of the heating resistor, therefore, the downstream evaporator can be made inoperative by means of the refrigerant supply. This is utilised to regulate the temperature in a refrigerated compartment independently of the control of the compressor or to relieve the evaporator when the latter is to be defrosted with the aid of an additional defrosting device.In the known cases, the heating resistor has a constant heat output and is disposed beyond the capillary tube or the refrigerant conduit. However, this results in the disadvantage that, after the refrigerant has evaporated, an excessive heat output is available that leads to an excessive temperature rise and permits coking of the refrigerant oil that is initially dissolved in the refrigerant and has been released by the evaporation. Since this coking takes place in the capillary tube or immediately upstream thereof, blockages of the capillary tube are unavoidable.The invention is therefore based on the problem of providing a compressor refrigerator plant of the aforementioned kind in which there is no fear of a blockage of the capillary tube by carbonized oil.This problem is solved in accordance with the invention in that a chamber is provided upstream of at least a section of the capillary tube and that the electric heating resistor is a PTC resistor which is disposed in the chamber and which goes over from a low to a high resistance when a temperature range is exceeded between the evaporating temperature of the refrigerant associated with the pressure in the chamber and the coking temperature of the refrigerant oil.With this arrangement, the heating resistor is disposed in the refrigerant and therefore has the same temperature as the refrigerant. Since the heatng resistor is a PTC resistor, its resistance increases with a rise in temperature and its power output drops accordingly. There are markedly different resistances to both sides of a temperature range; with many PTC resistors, a surge of resistance is associated with a particular temperature. When the PTC resistor is switched on, therefore, an equilibrium temperature is set up at which the refrigerant can evaporate but the refrigerant oil cannot become coked. There is therefore no danger of blocking the capillary tube.As in known cases, such an apparatus can be used as a `switch` for the refrigerant in so far that the downstream capillary tube section is so dimensioned that it is permeable to liquid refrigerant but is practically impermeable to the refrigerant vapour produced in the chamber.In this way it is possible to control a refrigerant cabinet with two compartments of different temperature having their evaporators connected substantially in parallel and fed by a common compressor and condenser, in so far that a thermostat in the compartment of lower temperature controls the compressor and a thermostat in the compartment of higher temperature controls a switch for the PTC resistor.The fact that the PTC resistor tends to ensure a substantially uniform temperature in the chamber when it is operative also permits a very simply constructed defrosting apparatus to be provided which dispenses with expensive accessories such as magnetic valves for hot gas, special heating conduits at the evaporator, and the like. Such a defrosting apparatus is characterised in that the chamber is disposed between two capillary tube sections and the second capillary tube section is dimensioned so that it has a lower throttling resistance to the liquid refrigerant than does the first capillary tube section. In particular, it can be dimensioned so that the second capillary tube section offers substantially the same resistance to refrigerant vapour as both sections do to liquid refrigerant. This can be achieved in that, for the second capillary tube section, its length is selected to be shorter than for the first capillary tube section and/or its cross-section is selected to be larger. In this case, when the PTC resistor is operative it will continuously convert liquid refrigerant to superheated refrigerant vapour in the chamber. In vapour is throttled in its flow into the evaporator and effects defrosting. With the dimensions as stated, it is even possible to ensure that, during defrosting, the pressure in the evaporator is substantially the same as the evaporator pressure during normal operation.It is particularly favourable if there is a functional relationship between the compressor and the PTC resistor such that the compressor is at least temporarily functioning during defrosting. In this way the compressor sucks off the refrigerant vapour fed into the evaporator. The low suction also ensures that no excessively high evaporator pressures occur. At the same time, the condenser is filled so that, after defrosting, the original temperature can be rapidly re-establishd in the refrigerated space.This functional relationship may be given in many ways. For example, the switch for the PTC resistor can also energise the compressor motor. However, the defrosting circuit can also be coupled to the compressor circuit in any other manner, either mechanically, electrically or thermally. A very simple solution is obtained if the PTC resistor is operable deliberately or automatically, e.g. in response to the presence of a layer of frost on the evaporator, and the compressor is controllable by a thermostat in the refrigerated space. Switching on of the PTC resistor can be controlled manually, by a time clock, by a temperature sensor or the like. In each case, the subsequent interruption in the supply of the liquid refrigerant leads to heating of the refrigerated space which, in turn, allows the compressor to start by way of the thermostat.
