THAR22C ヒートポンプ + エアコン + 冷却、2つのコンデンサーと2つの蒸発器（水/空気）、コンピュータ制御（PC）

The Computer Controlled Heat Pump + Air Conditioning + Refrigeration with 2 Condensers and 2 Evaporators (Water/Air)), "THAR22C", has as aim introduce the student to the study of the heat pumps, air conditioning and refrigeration, as well as the analysis and determinationof the operation typical parameters of the unit depending on the two types of fluids used in the processes of evaporation and condensation(air and water).

This unit can have different applications, depending on the type of cold focus or hot focus used in theprocesses of evaporation and condensation. This unit consists of the following stages:

• 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 pressuresensor, 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 transfersits 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 thecoolant 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 circulatesthrough the valve of expansion, which causes a fall of pressure and temperature of the coolant. At the end of this stage, the pressureand 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 absorbsthe 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 coolantare measured by means of a pressure sensor, a manometer and a temperature sensor. Finally, the coolant circulates through a liquidseparator 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). Inaddition, the unit includes a high pressure control to avoid an excess of pressure in the unit.

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