Thermosys™ 4.3 Components

Automatic Expansion Valve

Automatic Expansion Valve - New in 4.3: Models a simple automatic expansion valve using a map. Can be used to simulate discharge or evaporator pressure regulators.

Box Model

Box Model - A virtual refrigerated space with various thermal loads; for example a chilled freight container.

Compressor

Compressor - A devices that compresses low pressure and temperature refrigerant to a high pressure and temperature based on user defined volumetric and adiabatic efficiency maps.

Condenser

Condenser - A heat exchanger model that transfers heat from the refrigerant to the ambient air causing the refrigerant to condense from a vapor to a liquid.

Electronic Expansion Valve (EEV) Maps

Electronic Expansion Valve (EEV) Maps - Electronically controlled throttling valve that creates an abrupt reduction in pressure and temperature of the refrigerant. (Table lookup maps between input variables and mass flow rates.)

Electronic Expansion Valve (EEV) Poly

Electronic Expansion Valve (EEV) Poly - Electronically controlled throttling valve that creates an abrupt reduction in pressure and temperature of the refrigerant. (Polynomial fits between input variables and mass flow rates.)

Evaporator

Evaporator - A heat exchanger model that transfers heat from the refrigerated space to the refrigerant causing the refrigerant to evaporate into a vapor.

Humidity Condenser

Humidity Condenser - New in 4.3: Simulates a condenser using a moving-boundary, lumped parameter approach.

Humidity Evaporator

Humidity Evaporator - New in 4.3: Simulates an evaporator using a moving-boundary, lumped parameter approach.

Internal Flow Loss (Hydro Resistance)

Internal Flow Loss (Hydro Resistance) - Model that simulates hydrodynamic pressure drop due to internal flow resistance.

P-h Live Plotter

P-h Live Plotter - New in 4.3: This block allows live feedback of the active phase cycle on a P-h plot

Receiver

Receiver - A vessel at the exit of the condenser to store refrigerant which exits as a saturated liquid.

Thermostatic Expansion Valve (TXV)

Thermostatic Expansion Valve (TXV) - A throttling valve that regulates the degree of superheat of the refrigerant at the exit of the evaporator.

Two Fluid Plate Condenser

Two Fluid Plate Condenser - This block simulates a plate condenser system. Unlike the standard evaporator, it does not assume Air is the second fluid, and allows both fluids to be user-defined.

Two Fluid Plate Evaporator

Two Fluid Plate Evaporator - This block simulates a plate evaporator system. Unlike the standard evaporator, it does not assume Air is the second fluid, and allows both fluids to be user-defined.
