Definitions

  • the present invention relates to the method of regulating refrigerant/liquid flow in refrigeration, air conditioning and other industries so that maximum capacity, efficiency and safety is achieved at lower energy cost.
  • capillary tubes or the thermal Expansion valves are used for controlling the flow of refrigerant in refrigeration industries
  • First object of the "Energy Saving Expansion Device” is to allow more flow of the refrigerant at the lower condenser pressure to get higher cooling capacity and efficiency. And reduce the refrigerant flow at the higher condenser pressure to safeguard against overloading compressor. So that maximum capacity and efficiency is achieved without overloading compressor at higher ambient condition.
  • Second object is to avoid/minimize vapor passing to the evaporator from condenser at any worst condensing condition.
  • Figure 1 and 2 shows the construction of the valve.
  • Figure 1 illustrates
  • Figure 2 illustrates
  • This Expansion Device consists of valve body (3) with inlet port (1) outlet port(2) and port (8) which is connected to the outlet port.
  • this body small piston (4A) with hole and big piston (6) moves.
  • inlet pressure valve Irrespective of inlet pressure valve will always maintain preset constant flow (when density is constant).As the condenser pressure increases It will put more force on the left side of the piston (6) which will compress spring (7) and piston( 6) will move to right side, this will reduce the preloading of the spring (5) which will cause piston (4A) to close outlet port for lesser pressure drop across the piston (4A) and hence reduce the flow of the refrigerant
  • Figure 2 is the alternative construction for Figure 1 In this arrangement the piston (4B) has no hole. But the small length of the capillary tube (9) which is connected to the valve body (3) as shown in figure 2. Flow of liquid refrigerant through tube (9) will cause pressure drop across two faces of the piston (4B) and move piston (4B) to the right side to partially close the outlet port(2). Rest of the construction and working is same as figure 1.
  • Case 3 Alternative to piston (6) and spring (7), Bellow/diaphragm and spring construction can be used to do the same function of reducing pre- compression of the spring (5) at higher condenser pressure.

Abstract

Procédé de régulation de flux de réfrigérant/liquide dans la réfrigération et autres branches d'industrie. On décrit un dispositif d'expansion économiseur d'énergie qui vise premièrement à admettre un flux de réfrigérant supérieur à une pression de condenseur inférieure, dans le but d'augmenter la capacité/l'efficacité et de réduire la consommation d'énergie spécifique. Ce dispositif vise deuxièmement à réduire le flux de réfrigérant à une pression de condenseur supérieure, de manière à atteindre une capacité maximum sans surcharger le compresseur. Troisièmement, le dispositif permet d'éviter/de réduire au minimum le passage de vapeur dans l'évaporateur à partir du condenseur, sous les conditions de condensation les plus défavorables susceptibles d'être envisagées, pour sauvegarder le compresseur et le système. Quatrièmement, le dispositif décrit repose sur l'utilisation de valve seule fonctionnant par charge de pression et chute de pression statique relativement à l'écoulement de liquide/gaz, pour assurer le contrôle de flux.
