A screw rod water source heat pump set belongs to the technical field of water source heat pump air conditioner. The water source heat pump set comprises a compressor, a dry evaporator, a drying filter, a condenser and a throttling element, and is characterized in that the throttling element adopts an electronic expansion valve (4) and a throttling orifice plate (5) which are connected in parallel; and the condenser comprises two liquid roads, one road passes the expansion valve (4), the other road passes the throttling orifice plate (5) and a magnetic valve (6) connected in series with the throttling orifice plate (5), and the two roads are connected with the dry evaporator (7) after merging with each other. The structural style guarantees the stable and efficient operation of the screw rod water source heat pump set, and avoids the defects of mechanical failure, low reaction speed and narrow regulating range of a thermal expansion valve, and enables the set to be more stable and energy saving.
Description
Technical field
The utility model design screw water source heat pump units belongs to the water source heat pump air-conditioner technical field.
Background technology
At present, in a lot of big cities, people adopt water source heat pump units to carry out cooling and warming, water source heat pump units is than general air conditioner energy saving, but most of large-scale water source heat pump units all adopt heating power expansion valve as restricting element, unit is carried out Flow-rate adjustment, and this kind scheme adjustable range is narrow, degree of regulation is poor, does not fully reach purpose of energy saving.
The utility model content
The technical problems to be solved in the utility model is: poor as the unit capacity adjusting that restricting element brings because of the employing heating power expansion valve at above-mentioned water source heat pump units, unit reaches the problem that regulating cycle is long, energy consumption is high of stable operation, provides a kind of unit operation stable, energy-conservation water source heat pump units.
The technical scheme that its technical problem that solves the utility model adopts is: this screw water source heat pump units, comprise compressor, dry evaporator, device for drying and filtering, condenser and restricting element, it is characterized in that: the restricting orifice that restricting element adopts electric expansion valve and is in parallel with it, condenser divides two-way liquid road, one the tunnel through electric expansion valve, lead up to the magnetic valve of restricting orifice and series connection with it, two-way liquid road merges the back and links to each other with dry evaporator.
Compressor is a screw compressor.
Electric expansion valve is a kind of refrigerant to be become the element of low-temp low-pressure refrigerant liquid by the cooling medium liquid body segment stream of middle temperature high pressure, by the stepper motors in 3810 steps, can control cold medium flux accurately.
Restricting orifice is that refrigerant is become the element of low-temp low-pressure refrigerant liquid by the cooling medium liquid body segment stream of middle temperature high pressure, and characteristics are that capacity regulating is poor, and governing speed is slow, by with the acting in conjunction of electric expansion valve, reach the configuration of cost and best performance.
Screw compressor is a kind of rotary type displacement formula compressor.It utilizes the variation of the teeth groove volume of screw rod and position to finish suction, compression and the exhaust process of steam.Thereby the refrigerant vapor compression of low temperature, low pressure is become the refrigerant vapour of HTHP.
From the condenser two-way liquid road of coming out, lead up to magnetic valve and restricting orifice, lead up to electric expansion valve in addition, two-way gathers the back inflow evaporator, under fan-out capability requires less than compressor fully loaded 50% situation, the closed electromagnetic valve of connecting with restricting orifice, restricting orifice is inoperative, the sub-load throttling adopts electric expansion valve to carry out flow-control, under the situation of fan-out capability greater than compressor fully loaded 50%, the magnetic valve of connecting with restricting orifice is opened, and adopts electric expansion valve and restricting orifice acting in conjunction as restricting element, reaches purpose of energy saving.
Compared with prior art, the beneficial effect that had of screw water source heat pump units of the present utility model is:
This version has guaranteed stable, the efficient operation of screw water source heat pump units, has avoided because the mechanical breakdown and the reaction speed of heating power expansion valve are slow, and the shortcoming that adjustable range is narrow makes unit stable, energy-conservation more.
