Abstract
A refrigerant condenser set so that a condensation distance L (mm) of the condenser falls between 400+1180 de and 700+1180 de where de (mm) is the equivalent diameter of the tubes forming the core. By setting the condensation distance L in this way, the heat exchange rate becomes higher and it is possible to determine the number of turns required for the distance L.
Claims2
A refrigerant condenser comprising:
- a plurality of superposed tubes having opposing ends,
- a pair of headers joined to the tubes at the ends thereof, and
- separators disposed inside the headers for dividing the tubes into a plurality of groups,
- a high temperature, high pressure gaseous refrigerant flowing through the tube groups changing in direction of flow in the headers,
- when the number of times the direction of flow is changed in the headers is N and the distance between the pair of headers is W (unit:
- mm), the distance W being selected within the range of 300 to 800 mm, the condensation distance L (unit:
- mm) of the refrigerant is expressed by the equation:
- L=(N+1)W, and
- the condensation distance L (unit:
- mm) is L=400+1180 de to 700+1180 de where the equivalent diameter in the tubes corresponding to the tube area is de (unit:
- mm), and the equivalent diameter de (unit:
- mm) of the tubes is less than 1.15 mm,
- the number N being an integer rounded from the expression (L/W)-1.
