Abstract
The utility model discloses a water-cooled water chilling unit with an energy adjuster. A vent of a compressor is connected with a condenser, the condenser is connected with a dry filter, the dry filter is connected with sight glasses, the sight glasses are connected with an electromagnetic valve, the electromagnetic valve is connected with a thermostatic expansion valve, the thermostatic expansion valve is connected with an evaporator, and the evaporator is connected with a suction port of the compressor, thereby forming a loop. The water-cooled water chilling unit has the technical effects that the energy adjuster can be used for automatically controlling the suction pressure of the water-cooled water chilling unit, and when the suction pressure of the unit is lower than a low pressure control value, the suction pressure of the compressor is automatically adjusted, so that the water-cooled water chilling unit is prevented from starting and stopping frequently due to the too low suction pressure, and the normal work of the water-cooled water chilling unit is guaranteed.
Description
Technical field
The utility model relates to a kind of water-cooled handpiece Water Chilling Units, relates in particular to a kind of water-cooled handpiece Water Chilling Units with energy conditioner.
Background technology
When external load reduces; the pressure of inspiration(Pi) of existing water-cooled handpiece Water Chilling Units will descend; when being reduced to the low voltage control value when following; unit is shut down because of low-voltage variation; this will affect the normal operation of unit and the performance of compressor will be caused very macrolesion; for so that the water-cooled handpiece Water Chilling Units works on and effectively protects compressor, provide a kind of water-cooled handpiece Water Chilling Units with energy conditioner under underload.
Summary of the invention
The purpose of this utility model has been to provide a kind of water-cooled handpiece Water Chilling Units with energy conditioner, utilize energy conditioner automatically to control the pressure of inspiration(Pi) of water-cooled handpiece Water Chilling Units, when the unit pressure of inspiration(Pi) is lower than the low voltage control value, automatically regulate the pressure of inspiration(Pi) of compressor, avoid the water-cooled handpiece Water Chilling Units to cross low frequent start-stop because of pressure of inspiration(Pi), guarantee the normal operation of water-cooled handpiece Water Chilling Units.
The utility model is achieved like this, comprise evaporimeter, heating power expansion valve, visor, capacity adjusting valve, the energy adjustment magnetic valve, device for drying and filtering, condenser, the capacity adjusting valve angle valve, compressor, the exhaust outlet that it is characterized in that compressor connects condenser, condenser connects device for drying and filtering, device for drying and filtering connects visor, the visor connected electromagnetic valve, magnetic valve connects heating power expansion valve, heating power expansion valve connects evaporimeter, evaporimeter connects compressor air suction interruption-forming loop, in addition, condenser connects the capacity adjusting valve angle valve, and the capacity adjusting valve angle valve connects the energy adjustment magnetic valve, and the energy adjustment magnetic valve connects capacity adjusting valve, capacity adjusting valve connects evaporimeter inlet, capacity adjusting valve angle valve, the energy adjustment magnetic valve, capacity adjusting valve forms the energy conditioner of water-cooled handpiece Water Chilling Units.
During unit operation, when suction pressure of compressor drops to the low voltage control value when following, energy adjustment magnetic valve and capacity adjusting valve are opened automatically, the refrigerant gas of HTHP enters the evaporimeter air intake duct, and pressure of inspiration(Pi) is lower, and the open degree of capacity adjusting valve is larger, the refrigerant amount that flows to the evaporimeter suction line is also just more, so that the pressure of inspiration(Pi) of compressor rises, effectively prolonged the working time of compressor, avoided the frequent start-stop of compressor.
Technique effect of the present utility model is, utilize energy conditioner automatically to control the pressure of inspiration(Pi) of water-cooled handpiece Water Chilling Units, when the unit pressure of inspiration(Pi) is lower than the low voltage control value, automatically regulate the pressure of inspiration(Pi) of compressor, avoid the cold unit of water-cooled to cross low frequent start-stop because of pressure of inspiration(Pi), guarantee the normal operation of water-cooled handpiece Water Chilling Units.
Description of drawings
Fig. 1 is fundamental diagram of the present utility model.
In the drawings 1, condenser 2, capacity adjusting valve angle valve 3, device for drying and filtering 4, visor 5, energy adjustment magnetic valve 6, heating power expansion valve 7, capacity adjusting valve 8, compressor 9, evaporimeter.
The specific embodiment
As shown in Figure 1, the utility model is achieved like this, the exhaust outlet of compressor 8 connects condenser 1, condenser 1 connects device for drying and filtering 3, device for drying and filtering 3 connects visor 4, visor 4 connected electromagnetic valves, magnetic valve connects heating power expansion valve 6, heating power expansion valve 6 connects evaporimeter 9, evaporimeter 9 connects compressor 8 air entries and forms the loop, in addition, condenser 1 connects capacity adjusting valve angle valve 2, and capacity adjusting valve angle valve 2 connects energy adjustment magnetic valve 5, and energy adjustment magnetic valve 5 connects capacity adjusting valve 7, capacity adjusting valve 7 connects evaporimeter 9 inlets, capacity adjusting valve angle valve 2, energy adjustment magnetic valve 5, capacity adjusting valve 7 forms the energy conditioner of water-cooled handpiece Water Chilling Units.
1) during unit operation, cold-producing medium is compressed into high temperature and high pressure gas in screw compressor, enter condenser with thermal release to cooling water, then pass through device for drying and filtering, visor, behind the heating power expansion valve reducing pressure by regulating flow, absorb the heat of vaporization (chilled water that is cooled is delivered to each end, satisfies user's needs) in the chilled water in evaporimeter, cold-producing medium becomes low-temp low-pressure gas and returns screw compressor.
2) in running, when suction pressure of compressor drops to the low voltage control value when following, energy adjustment magnetic valve and capacity adjusting valve are opened automatically, the refrigerant gas of HTHP enters the evaporimeter air intake duct from the capacity adjusting valve angle valve, and pressure of inspiration(Pi) is lower, and the open degree of capacity adjusting valve is larger, the refrigerant amount that flows to the evaporimeter suction line is also just more, so that the pressure of inspiration(Pi) of compressor rises, effectively prolonged the working time of compressor, avoided the frequent start-stop of compressor.
