The document discusses Cold Energy, a company developing an energy efficiency kit for refrigeration and air conditioning systems. The kit introduces a turbocharger and two heat exchangers to a conventional refrigeration cycle to recover energy and reduce energy usage. Prototypes are being tested and the product is planned to be commercialized for low-temperature applications from 2019-2021 before expanding to medium- and high-temperature sectors. The document outlines Cold Energy's technology, development timeline, market approach, and integration of the kit into refrigeration systems with minimal interface requirements.

STARTING POINT AND INNOVATIVE IDEA
COMPRESSION REFRIGERATION CYCLE
Scheme
INEFFICIENCY POINT:
The expansion valve brings the
refrigerating liquid from high
pressure to low pressure with no
use of available potential energy

COMPRESSION REFRIGERATION CYCLE + TURBOALGOR
Scheme
Heat exchangers
The gas produced in the heat
exchangers is processed in the
turbocharger, which makes a
pre-compression of the
refrigerant and thereby
reduces the energy
requirements of the main
compressor.
The innovation is related to the introduction of a
turbocharger and two energy recovery heat
exchangers within a conventional refrigeration plant

MARKET SCENARIOUS
DEFINITION OF CONTEXT PARAMETERS:
- Evaporating temperature
- Type of used refrigerant
- Power range
CURRENT GOAL: commercialization of energy efficiency kits to be used in
low temperature applications with power between 40-200 kW and using
synthetic refrigerants with physical properties similar to R404a
Subsequently, a wider power range is expected to meet the main refrigerator market
requirements and specific components for natural refrigerants will be developed

TECHNICAL AND DESIGN ASPECTS
COLD ENERGY KIT is applicable to both new and existing
installations. It is essential to accomplish a simple and fast
integration. Two complementary paths have been identified:
• Main and auxiliary components are contained in a chassis
• The turbocharger is installed in the main compressor
