Novel phase change heat storage refrigeration and heating system

Abstract

The invention discloses a novel phase change heat storage refrigeration and heating system. The novel phase change heat storage refrigeration and heating system comprises a compressor, a phase changeheat storage tank, an air-cooled condenser, a double-pipe evaporator and a direct evaporation air cooler. A refrigerant outlet in the bottom of the compressor communicates with the left end of the phase change heat storage tank, and the right end of the phase change heat storage tank communicates with the left end of the air-cooled condenser. The right end of the air-cooled condenser communicateswith the right end of the double-pipe evaporator, and the left end of the double-pipe evaporator communicates with the right end of the direct evaporation air cooler. A refrigerant outlet in the leftend of the direct evaporation air cooler communicates with a refrigerant inlet in the top of the compressor. By means of the novel phase change heat storage refrigeration and heating system, the wasteproblem of condensation heat in an existing heat pump air-conditioner can be effectively solved, the condensation heat emitted in the refrigeration process of the heat pump air-conditioner can be reliably and effectively utilized while the original refrigeration and heating functions of the heat pump air-conditioner are reserved, the utilization rate of energy is increased and thermal pollution to the outdoor environment by the condensation heat is avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a novel phase-change thermal storage cooling and heating system. Background technique [0002] At present, heat pump air conditioners have been widely used in people's work and life, and have become an indispensable and important part of people's work and life. [0003] For traditional heat pump air conditioners, when cooling in summer, the condensation heat emitted by the condenser is directly discharged to the outside, which not only causes direct waste of condensation heat, but also causes thermal pollution of the outdoor environment by condensation heat. [0004] Therefore, there is an urgent need to develop a technology that can reliably and effectively utilize the condensation heat emitted by the heat pump air conditioner during the cooling process while retaining the cooling and heating functions of the original heat pump air conditioner, and improve energy utiliz...
