LTLF Series Screw Compressor Air Source Heat Pump, Air to Water Heat Pump

TECHNICAL DESCRIPTION

Nominal cooling working condition:

1) Condenser inlet temperature DB 35 ℃, WD 24 ℃.

2) Evaporator inlet temperature 12℃, outlet temperature 7 ℃

Nominal heating working condition:

1) Condenser inlet temperature DB 7 ℃, WD 6 ℃.

2) Evaporator inlet temperature 40℃, outlet temperature - ℃

Fin type air-cooled condenser

Fin type air-cooled condenser adopts imported high purely, seamless screw thread copper and special aluminum fin after mechanical expanding joint closely. It ensures fin type condenser work in best efficiency.

Tube in tube and Shell and Tube type evaporator

1)It is tube in tube and Shell and Tube structure with new developed fire-proof and water-proof material as heat preservation. The water-side working pressure may reach to 2.0 MPa.

2) There is PVC engineering plastic breakwater inside of evaporator with strong anti-corrosion ability. Chilling water circuitous goes up and down to increase tumble effect, and heat exchange ability.

3) Adopt new technology DAC weave interior screw threat, high efficient heat exchange tube to ensure good cooling characters.

Semi-hermetic screw compressor

The unit uses imported semi-hermetic screw type compressor. Comparing piston type compressor, the semi-hermetic screw type compressor has following advantages:

1) Less accessories (Approximately 1/3 of piston compressor). The unit structure is simply and long service life).

2) The unit EER ≥3.1W/W;

3) Screw type compressor may adjust energy in range 25% - 100%.

Four-way valve

LVTE heat pump type air-cooled water chiller adopts PE four-way valve from Unit State, so that solves reversing and system consume great problem exist in other same kind of products.

Condenser

1) Axial fan, protection grade reached IP55. long service ling and reliable.

2) External rotator and blades combined into integrity. Design compact, run in high speed and low noise.
