Title: Daiki Kayashima: Innovator in Refrigeration Technology

Introduction

Daiki Kayashima is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of refrigeration technology, holding a total of 3 patents. His innovative work focuses on enhancing the efficiency and functionality of defrost systems.

Latest Patents

Kayashima's latest patents include a defrost system that utilizes an electric heater for thermosiphon. This system features a thermosiphon defrost circuit branched from a circulation line. During defrosting, a CO refrigerant within a fin-tube heat exchanger undergoes a two-phase change, creating a CO circulation path. The system incorporates electromagnetic opening/closing valves that maintain a closed circuit during defrosting. Additionally, a first electric heater is strategically placed above the thermosiphon defrost circuit to facilitate the natural circulation of the CO refrigerant.

Another notable patent is a defrost system for refrigeration apparatus and cooling units. This system includes a cooling device located in a freezer, a heat exchanger pipe, and a drain receiver unit. It also features a refrigerating device for cooling and liquefying CO refrigerant, along with a refrigerant circuit that allows the CO refrigerant to circulate. The defrost circuit branches from the heat exchanger pipe, forming a CO circulation path. An on-off valve ensures that the CO circulation path remains a closed circuit, while a pressure adjusting unit regulates the pressure of the CO refrigerant.
