Abstract

The regulator is a refrigerant regulator intended for heatpumps and refrigerators. It has a built-in receiver, which automatically absorbs redundant refrigerant. It is a hermetic closed device without removable parts. It is robust and there is no need for adjustment. The regulator is composed of a heat exchanger with large heat capacity, a receiver and two pressure reducing valves. The two valves behave different on boiling fluid flow. One of them, named a heat sensitive valve, restricts fluid flow when the fluid is boiling. In the other valve, named a pressure sensitive valve, the boiling has no influence on the fluid flow. The regulator controls the refrigerant flow from the receiver to the evaporator by means of the pressure in the receiver-and the pressure in the receiver is controlled, via the heat exchanger, by the need of refrigerant in the evaporator. This way of control ensures 100% use of the evaporator, the suction gas is superheated, and the liquid from the condenser is sub-cooled. These factors improve the relation between the cooling capacity and the power consumption with more than 10%.

Description

Patentkrav: 1 .En køIemiddelregulator( 16), bestående af en væskebeholder (19), en varmeveksler med stor varmekapacitet (18), en varmefølsom dyse (17) og en trykfølsom dyse (20).Patent claims: 1. A refrigerant regulator (16), consisting of a liquid container (19), a heat exchanger with high heat capacity (18), a heat-sensitive nozzle (17) and a pressure-sensitive nozzle (20).

Kendetegnet ved a) At væsketrykket reduceres i to trin. Først over den varmefølsomme dyse (17), dernæst over den trykfølsomme dyse (20). b) At trykket i væskebeholderen (19) styres af sugegassens væskeindhold via varmeveksleren (18). c) at varmeveksleren har en stor varmekapacitet, som dæmper temperatursvingninger så meget at resonans mellem fordamper og varmeveksler undgås. d) At væskestrømmen gennem den trykfølsomme dyse (20) ikke reagere på væskens temperatur, men kun på trykfaldet over dysen.Characterized by a) That the fluid pressure is reduced in two steps. First over the heat-sensitive nozzle (17), then over the pressure-sensitive nozzle (20). b) That the pressure in the liquid container (19) is controlled by the liquid content of the suction gas via the heat exchanger (18). c) that the heat exchanger has a large heat capacity which dampens temperature fluctuations so much that resonance between evaporator and heat exchanger is avoided. d) That the fluid flow through the pressure-sensitive nozzle (20) does not respond to the temperature of the liquid, but only to the pressure drop across the nozzle.
