Product Description

Commercial Air Conditioners Water Source Heat Pump For Grand Hotel

1. Eurostars screw type water source heat pump brief introduction
Eurostars Water (ground)source heat pumps take geothermal resources (groundwater, ground, surface water, seawater etc.)as energy source and use a little electric energy to release heat in summer and absorb heat in winter. The system uses special heat exchange method, around 70% of energy comes from water (ground), around 30% of energy comes from electricity, so the heat pump units have the characteristics of high efficiency and energy saving compared to traditional air conditioning. Eurostars water cooled heat pump chillers are widely applied in the following areas:
Office buildings, schools, hotels, entertainment cities
Indoor games halls, indoor gymnasium
Greenhouses, industrial buildings, plants
Malls, hospitals, large public places, villas
Staff baths, sauna
Any building which needs HVAC


2. Eurostars screw type water source heat pump main components
(1)Compressor
The compressor uses the positive displacement double helix design, suitable for many kinds of refrigerant, the compressor contains two spiral rotor, the negative rotor was driven by positive rotor, the double torsion positive displacement makes the pure rotation movement, make the vibration to be minimum, wide adjustment scope, it has the high efficiency and smooth air current's characteristic in the air absorption, compression and air exhaust processes, the compressor's lubrication and the air seal selects the differential pressure oil supply method, do not need lubrication oil pump.
The compressor is installed oil separator inside. The oil separator and the compressor is combined, enable the compressor to have the smallest outlook, simplifies the cold intermediary circulation process. There is second oil separator between air exhaust outlet and condenser for full liquid type chiller to let less cooling oil enter onto the system and improve the heat exchange efficiency. The slide valve driven by electric valve and liquid pressure system made into the float capacity adjustable system, it can come true part load operation, and the compressor can reach 25%-100% subsection adjustment. It also can use fuzzy control principle to realize the continuance energy regulation matching with the building load fully.
(2)Shell & tube evaporator & condenser
Shell: high quality steel plate special for pressure vessel; The manufacturing and the experiment conform to the national standards "Refrigerating unit with Pressure vessel" NB/T47012-2010 rules. Adopting fire and water proof thermal insulation material for outside; the baffle of evaporator is PVC project plastic with strong resistance to corrosion and tight seal, making the cooling water up and down along the baffle to improve the turbulent flow effect and the heat exchanging ability. There is current-sharing equipment for refrigerant inlet to keep the same refrigerant in each heat exchange tube and improve the whole chiller heat exchange efficiency.
Copper tube: high efficiency DAC corrugated type inner thread heat exchange copper tube; strengthening refrigerant side heat exchange ability and improving the heat transfer coefficient to insure the unit good cooling and heating effect.
(3)Expansion valve
Electric expansion control system can assure control accuracy; controlling the refrigerant to air suction super heat and pressure matched with electric system to insure the chiller operation at the best condition and play the chiller biggest ability.
 (4)Power distribution control box:
Including compressor start equipment, power protector and micro computer controller. Famous brand wide temperature type electrical components. The microcomputer controller uses the well-known brand wide warm electric appliance parts, the microcomputer controller can work stably under the ambient temperature from -15ºC to 65ºC, it has the automatic control function and has RS-232, the RS-485 standard communication connection joint, may realize the remote control.
 
Microcomputer control characteristic:
The enactment and show of cold water temperature. Auto energy control and start & stop function. Touching type screen operation mode. Displaying current flow (selected parts) and set valve, operating state, warming and compressor running hours. It may accept remote starting and off signal. The outer wire failure makes the power off, after the power restores, the unit will be operating automatically. It has password parameter protection function. Auto capacity controlling and start & stop controlling; Touching type screen operating mode; It may accept remote starting and off signal.



3. Eurostars screw type water source heat pump features
(1)Adopt advanced structure design and reasonable structure matching, the chiller unit energy efficiency ratio is high.
(2)Variable capacity adjustment, flexible start and stop, comfortable and energy-saving.
(3)Large touch screen, powerful control function, with fault self-diagnosis and other functions.
(4)Multiple safety protection measures, safe and reliable operation of the unit.
(5)High efficiency shell and tube dry evaporator.
(6)The optional electronic expansion valve can control the liquid supply of refrigerant timely and accurately, greatly improving the chiller efficiency.
