Air to refrigerant heat exchanger with phase change material

摘要

A thermal energy heat exchanger for an air conditioning system includes a row of first tubes, a row of second tubes, and a row of third tubes. Inside, heat is exchanged between air, refrigerant, and phase change material, also known as PCM, cool storage material, cold storage material, and latent heat storage material. The first row of tubes carries refrigerant. A portion of the second row of tubes and a portion of the third row of tubes carry refrigerant. The remainder of the second and third rows of tubes carry phase change material. The phase change material can be associated with a phase change material manifold. Advantageously, the melting point of phase change material in the second tubes can be different from the melting point of the phase change material in the third tubes.

主权项

1. A thermal energy exchanger for a heating, ventilating, and air conditioning system that exchanges thermal energy between a first fluid and a second fluid, the thermal energy exchanger comprising:
a first row of first tubes, wherein each of the first tubes receives the first fluid therein; a second row of second tubes disposed directly downstream of the first tubes with respect to a flow path of the second fluid, a portion of the second tubes receiving the first fluid therein, the remaining second tubes including a phase change material disposed therein; in the second row, the second tubes receiving the first fluid therein and the second tubes including the PCM disposed therein alternate; a third row of third tubes disposed directly downstream of the second tubes with respect to the flow path of the second fluid, a portion of the third tubes receiving the first fluid therein, the remaining third tubes including a phase change material disposed therein; the second tubes with phase change material disposed therein contacting the third tubes receiving the first fluid therein; the second tubes receiving the first fluid therein contacting the third tubes with phase change material disposed therein.
