Abstract
In refrigerating systems and heat pump systems, thermostatic expansion valves are used to deliver a precisely correct quantity of refrigerant to an evaporator under changing operational conditions. The valve shall maintain equilibrium between delivery of the refrigerant and the removal by suction of said refrigerant under all operating conditions. In order to prevent the expansion valve of a refrigerating or heat pump system from remaining closed due to low bulb temperature, where several refrigerating batteries/evaporators with expansion valves are arranged in parallel and where a substantially constant suction pressure prevails and closing of the valve will not therefore influence the system suction pressure, there has been arranged over the expansion valve, between the high pressure side and the low pressure side, a connection (5, 6, 8) which has an adjustable or fixed through-flow area and which will guarantee that a minimum amount of refrigerant is vapourized in the evaporator such as to produce superheated gas for heating a bulb connected to the expansion valve.
