Heat Exchangers
Use these blocks to model heat exchange between different domains or between topologically distinct networks.
If a specific component does not yet exist in a domain library, you can build your own using the Simscape™ language. For more information, see Creating Custom Components.

EV Battery Cooling System
This demo shows an Electric Vehicle (EV) battery cooling system. The battery packs are located on top of a cold plate which consists of cooling channels to direct the cooling liquid flow below the battery packs. The heat absorbed by the cooling liquid is transported to the Heating-Cooling Unit. The Heating-Cooling Unit consists of three branches to switch operating modes to cool and heat the battery. The Heater represents an electrical heater for fast heating of the batteries under low temperature conditions. The Radiator uses air-cooling and/or heating when the batteries are operated stably. The Refrigerant system is used for cooling the overheated batteries. The refrigeration cycle is represented by the amount of heat flow extracted from the cooling liquid. The system is simulated under either FTP-75 drive cycle or fast charge scenarios with different environment temperatures.
Engine Cooling System
Model an engine cooling system with an oil cooling circuit.
House Heating System
Model a simple house heating system. The model contains a heater, a controller, and a house structure with four radiators and four rooms. Each room exchanges heat with the environment through its exterior walls, roof, and windows. Each path is simulated as a combination of a thermal convection, thermal conduction, and the thermal mass. It is assumed that heat is not transferred internally between rooms. The heater consists of a furnace, a boiler, an accumulator, and a pump to circulate hot water in the system. The controller starts admitting fuel into the furnace if the overall average temperature of rooms falls below 21 degree C and it stops if the temperature exceeds 25 degree C. The simulation calculates the heating cost and indoor temperatures.
Residential Refrigerator
Models a basic refrigeration system that transfers heat between the refrigerant two-phase fluid and the environment moist air mixture. The compressor drives the R134a refrigerant through a condenser, a capillary tube, and an evaporator. An accumulator ensures that only vapor returns to the compressor.
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.
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.
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.
Vehicle HVAC System
Models the heating and cooling system of a passenger car. The cabin is represented as a volume of moist air exchanging heat with the external environment. The blower drives moist air through the evaporator, blend door, and heater core before returning to the cabin. The blend door controls the amount of air flow through the heater core. The recirculation door controls whether air is brought in from the external environment or from within the cabin.
