TL;DR: Based on the idea of making the frost absorb most of the heat generated by electric heater, a new method of defrosting is proposed in this paper, and its principle is to make the de-icing process at different locations complete simultaneously by optimizing the frost mass distribution on the evaporator.

TL;DR: In this paper, the implicit regression and explicit calculation method for the fast and stable calculation of refrigerant thermodynamic properties of saturated, two-phase, and superheated refrigerants was improved upon so it could be used with subcooled refrigerants.

TL;DR: In this paper, an isothermal state in the supercritical region is used as the reference state, and the implicit equations for supercritical refrigerants in this state and out of this state are established.

TL;DR: In this paper, four basic methods are proposed at first, i.e., using solid shelves to separate the cabinet into several chambers and sending cold air into each chamber; providing an cold air curtain to prevent heat leakage though front glass door; adjusting the flow direction of cold air to enhance convection in both sides of the cabinet; and adding air outlets in different chambers in the bottom of the wine cabinet to distract the heat in the return air.

TL;DR: In this paper, the authors investigated the feasibility of using an enthalpy exchanger (EE) to reduce the frost accumulation on the evaporator surface in a frost-free refrigerator.
