Air Liquefaction
Models a Linde-Hampson air liquefaction cycle using the two-phase fluid components. The compressor drives the vapor air through two heat exchangers, recuperator, expansion valve, and storage tank. The first heat exchanger contains water at atmospheric temperature, while the second heat exchanger contains refrigerant. The pressure drops as the cooled air passes through the expansion valve which results in condensation. The air and entrained condensation then pass through a receiver tank where the condensation separates from the air. The liquid air is stored in a receiver tank while the vapor air is circulated back to the compressor.

Electric Vehicle Thermal Management with Heat Pump
Models the thermal management system of a battery electric vehicle (BEV) that includes a heat pump for cabin heating. The system consists of two liquid coolant loops, a refrigerant loop, and a cabin air HVAC loop. The thermal loads are the batteries, the power electronics, and the cabin.
EV Battery Thermal Management System
An Electric Vehicle (EV) battery heating-cooling system. Maintaining the battery temperature within an optimal range is important for efficient charging and discharging. The model simulates either the FTP-75 drive cycle or a fast charge cycle at different environment temperatures. A thermal liquid coolant circuit conveys heat between the battery and the heating-cooling unit. For more information on designing EV battery cooling systems, see EV Battery Cooling System Design.
Electric Vehicle Thermal Management With CO2
Models the thermal management system of a battery electric vehicle (BEV) that uses a transcritical CO2 (R-744) refrigeration cycle for cooling and heating. The system consists of two liquid coolant loops, a CO2 refrigerant loop, and a cabin air HVAC loop. The thermal loads are the batteries, the power electronics, and the cabin.
Hydrogen Refueling Station
Models a hydrogen refueling station. Hydrogen is stored in low-pressure storage tanks at 200 bar at the station. A 3-stage intercooled compressor maintains the necessary pressure in a cascade buffer storage system so that the station is ready to dispatch hydrogen to any connected vehicles. The buffer is divided into high-pressure tanks at 950 bar, medium-pressure tanks at 650 bar, and low-pressure tanks at 450 bar. To avoid wasting compression energy, the lowest pressure buffer that is greater than the vehicle tank pressure is used to dispatch hydrogen. Priority valves switches between the different buffer tanks to control which buffer tanks to fill and discharge from.
Liquid Air Energy Storage System
Models a grid-scale energy storage system based on cryogenic liquid air. When there is excess power, the system liquefies ambient air based on a variation of the Claude cycle. The cold liquid air is stored in a low-pressure insulated tank until needed. When there is high power demand, the system expands the stored liquid air to produce power based on the Rankine cycle.
Liquid Hydrogen Storage and Transportation
Model a cryogenic tank by using Simscape™ Fluids™ blocks. Aviation and aerospace applications commonly use liquid hydrogen storage instead of compressed gas storage. Engineering challenges include minimizing liquid boil-off, managing tank internal pressure, and designing a robust storage tank.
PEM Fuel Cell System with the Gas Mixture Domain
Model a proton exchange membrane (PEM) fuel cell stack with a custom library and custom Simscape™ domain. You can download the library and model from MATLAB® Central File Exchange.
Photovoltaic Thermal (PV/T) Hybrid Solar Panel
Model the cogeneration of electrical power and heat using a hybrid PV/T solar panel. The generated heat is transferred to water for household consumption.
Refrigerant Modernization
Retrofit a Simscape™ cooling cycle that uses R410a to utilize R32, which is a refrigerant with a lower Global Warming Potential (GWP). The process involves modifying the nominal mass flow rate and refrigerant charge, while retaining the original evaporator and condenser specifications. For more information on designing a cooling cycle, see Model a Refrigeration Cycle and Refrigeration Cycle (Air Conditioning).
Residential Air Source Heat Pump
Models an air source heat pump system that is used to heat a residential building having hot-water radiators for heat distribution. The two-phase fluid refrigerant takes up heat from the environment moist air mixture and transfers heat to water. The compressor drives the R410a refrigerant through a condenser, a thermostatic expansion valve, and an evaporator. An accumulator ensures that only vapor returns to the compressor.
Residential Ground Source Heat Pump
Models a ground source heat pump system that is used to heat a residential building having hot-water radiators for heat distribution. The ground source heat pump uses R410a, a two-phase fluid refrigerant, as the working fluid. The heat pump takes up the naturally existing heat stored in the ground and transfers the heat to the hot-water radiators. The compressor drives the refrigerant through a condenser, a thermostatic expansion valve, and an evaporator. An accumulator ensures that only vapor returns to the compressor. A receiver ensures that only liquid returns to the thermostatic expansion valve.
Reversible Heat Pump
A refrigeration cycle that can operate in heat pump mode for heating and in air conditioning mode for cooling. The refrigerant is R-410A. The system consists of a compressor, an outdoor heat exchanger, an electronic expansion valve (EXV), an indoor heat exchanger, and an accumulator. A 4-way directional valve separates the compressor and accumulator from the rest of the system to control the refrigerant flow direction.
