In a vapor compression refrigeration cycle, the compressor, condenser, throttling device, and evaporator are four indispensable components, together forming a closed-loop system. Among them, the throttling device, although simple in structure, plays a crucial role in establishing high and low pressure differences and precisely controlling refrigerant flow. This article will provide a detailed introduction to the main types of throttling devices, their core functions, and their respective technical characteristics.

Welcome to Chiller's Science Corner! In practice, customers often ask, "When controlling the temperature of equipment, should I choose an air-cooled or water-cooled chiller?"

During the production and service of chillers, one of the most frequently asked questions is: "Can your chillers really operate stably for a long time?" This question reflects three major concerns that users generally have about chillers currently on the market:1. Concern about sudden shutdown: If the chiller stops working, it will delay the production schedule;2. Concern about unstable temperature control: fluctuating temperatures can affect product yield;
