Determining whether converting aging low-temperature refrigeration units to medium-temperature for a continuous 20-ton load is feasible or if new purpose-built equipment is needed.

No clear guidelines or decision-support tools exist for assessing the viability of converting old LT condensing units to MT, considering compressor and condenser limitations.

App Concept

RefrigerationRetrofit Planner

A web-based tool that evaluates the feasibility of converting low-temperature refrigeration systems to medium-temperature applications. It inputs unit specs and load profiles, calculates compressor amperage and condenser capacity, and provides a clear go/no-go recommendation, saving technicians and owners from costly trial-and-error.

Key Features

Input unit nameplate data (RLA, LRA, model, age) and load parameters
Automated calculation of compressor mass flow and amp draw at target SST
Condenser capacity check based on original LT vs current MT heat rejection
Go/no-go decision with risk assessment and recommended modifications (TXV, defrost, HGB)

Target Users: HVAC technicians, facility managers, and commercial refrigeration owners in food service, cold storage, and climate-controlled rooms with aging equipment.

Revenue Model: $49/month per user subscription or $99 per project consultation add-on
