Dual-source heat pump air and water laboratory equipment, increase the ground source heat pump

Dual air and water source heat pump equipment: 1, through the consumption of electric power equipment from the atmosphere, absorb heat and add water in hot water equipment built experimental apparatus heating. 2, the device cooling or heat cycle parts are clearly visible, neatly arranged in the experimental surface. 3, cooling or thermal cycling parameters can be measured, such as: a refrigerant flow, pressure and temperature, water temperature, the compressor power. Features: 1, the dual-source heat pumps, low-temperature heat are: air and water. 2, environmental adaptability, experiment equipment fast and stable. 3, the device can draw the refrigerant pressure during the experiment complete enthalpy diagram. 4, the choice of a low pressure, non-toxic, pollution-free refrigerant to the atmosphere: R134a. 5. Optional accessories: RE590 ground source heat pump module. Experimental feature: 1. Measure the input and the output of heat and electric power conversion efficiency between the two. 2. Draw laboratory equipment at different evaporation and condensation temperature, the performance curve of the refrigerant. 3. Draw the actual vapor compression cycle curve on the pressure-enthalpy diagram and can be compared with the ideal cycle. 4. Verify that the energy balance of the circulatory system. 5. assess the impact of the pressure ratio of the compressor of compression efficiency. 6. Assessment of the heat transfer coefficient between the evaporator and the condenser.
