Abstract
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.
