THIBAR22C Тепловой насос + кондиционер + обратное охлаждение с 2 конденсаторами и 2 испарителями (вода/воздух), управляемое с ПК

The Computer Controlled Rerversible Heat Pump + Air Conditioning + Refrigeration with 2 Condensers and 2 Evaporators (Water/Air),"THIBAR22C", has as aim introduce the student to the study of the heat pumps, air conditioning and refrigeration, as well as the analysisand determination of the operation typical parameters of the unit depending on the two types of fluids used in the processes of evaporationand condensation (air and water).

This unit can have different applications, depending on the type of cold focus or hot focusused in the processes of evaporation and condensation. This unit consists of the followingstages:

• Compression: This stage begins when the coolant enters to the compressor. This coolant is compressed, increasing its pressure and temperature. To measure these variables the unit includes a pressure sensor, a manometer and a temperature sensor.
• Condensation: The coolant has two possibilities: divert the coolant through the air condenser, or through the water condenser. The coolant transfers its heat to the water (or to the air) that flows for the condenser. At the end of this stage, the pressure and the temperature of the coolant are measured by means of a manometer and a temperature sensor.
• Expansion: The coolant circulates through an accumulator and a filter, to retain particles of condensate, and a flow sensor. Next it circulates through the valve of expansion, which causes a fall of pressure and temperature of the coolant. At the end of this stage, the pressure and the temperature of the coolant are measured by means of a manometer and temperature sensor.
• Evaporation: The coolant has two possibilities: divert the coolant through the air evaporator, or through the water evaporator. The coolant absorbs the heat of the water (or the air) that flows for the evaporator. At the end of this stage, the pressure and the temperature of the coolant are measured by means of a pressure sensor, a manometer and a temperature sensor. Finally, the coolant circulates through a liquid separator to retain liquid particles before going on to the compressor.

The condensers and evaporators have different sensors to the measure of the most important parameters (temperatures and flows). In addition, the unit includes a high pressure control to avoid an excess of pressure in the unit and a 4-way valve to change the direction of the coolant.

The 4-way valve (or cycle inversion valve) allows to obtain different combinations of Heat Pump, Air Conditioning and Refrigeration in a only unit.So that using the cycle inversion valve, we have 9 units in one, 6 of them Heat Pump + Air Conditioning + Refrigeration and 3 of them Heat Pump + Air Conditioning.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Management Software Packages, for controlling the process and all parameters involved in the process.
