Description
Technical field
But the Teat pump boiler of the utility model balance compressor pressure belongs to the technical field of Teat pump boiler.
Background technology
According to people's habits and customs, in temperature low more winter, people need more hot water usually, and the hot water water temperature that needs is higher.And common Teat pump boiler is because characteristic itself, and when temperature was low more, compressor air suction lateral pressure (low pressure just) can step-down; When needs were produced the higher hot water of temperature, compressor air-discharging lateral pressure (high pressure just) can uprise, at this moment; The low pressure step-down of machine set compressor, and high pressure has uprised, and just causes compressor high-low pressure pressure reduction very big; Influenced the efficient of unit, serious also can damage compressor; Simultaneously, because environment temperature is very low, through regular meeting the frosting phenomenon appears on the evaporimeter of common Teat pump boiler; In order from air, to absorb heat better; The frequent defrost of having to of common Teat pump boiler, like this, compressor just needs frequent startup-shutdown; The high frequent start-stop will cause the unit power consumption big, and efficient is not high.
The utility model content
The purpose of the utility model is to avoid the weak point of prior art, and provide a kind of can the balance compressor pressure, be beneficial to defrosting, energy-efficient
But the Teat pump boiler of balance compressor pressure
The purpose of the utility model reaches through following measure; But the Teat pump boiler of balance compressor pressure comprises by compressor, water tank heat exchanger, throttling arrangement, evaporimeter, controller and constituting; The compressor control line links to each other with controller, and the water tank heat exchanger is provided with refrigerant import and refrigerant exit, and the exhaust outlet of compressor is connected with the import of water tank heat exchanger refrigerant; Water tank heat exchanger refrigerant exit links to each other with the throttling arrangement import; The throttling arrangement outlet is connected to evaporator, and evaporator outlet is connected with the return-air mouth of compressor, and the exhaust outlet of compressor links to each other with the import of electromagnetism two-port valve; The outlet of electromagnetism two-port valve is connected to evaporator, and electromagnetism two-port valve control line is connected with controller.
The throttling arrangement of the utility model is heating power expansion valve or electric expansion valve.
The evaporimeter of the utility model is water-refrigerant heat exchanger or air-refrigerant heat exchanger.
The utility model is simple in structure, energy-efficient, safe and reliable, be a kind of can the balance compressor pressure, but be beneficial to the Teat pump boiler of the balance compressor pressure of defrosting.
Description of drawings
Accompanying drawing 1 is the principle schematic of the utility model.
Accompanying drawing 2 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure: compressor 1, water tank heat exchanger 2, throttling arrangement 3, evaporimeter 4, electromagnetism two-port valve 5, controller 6.
Shown in accompanying drawing 1, accompanying drawing 2; The utility model is made up of compressor 1, water tank heat exchanger 2, throttling arrangement 3, evaporimeter 4, electromagnetism two-port valve 5, controller 6; Water tank heat exchanger 2 is provided with refrigerant import and refrigerant exit, and the exhaust outlet of compressor 1 is connected with the 2 refrigerant imports of water tank heat exchanger, and water tank heat exchanger 2 refrigerant exits link to each other with throttling arrangement 3 imports; Throttling arrangement 3 outlets are connected to evaporimeter 4 imports; Evaporimeter 4 outlets are connected with the return-air mouth of compressor 1, and the exhaust outlet of compressor 1 links to each other with 5 imports of electromagnetism two-port valve, and 5 outlets of electromagnetism two-port valve are connected to evaporimeter 4 imports; Electromagnetism two-port valve 5 control lines are connected with controller 6, and compressor 1 control line links to each other with controller 6.
Cold-producing medium through throttling arrangement 3, gets into evaporimeter 4 from the compressor 1 water tank heat exchanger 2 of flowing through, and after flowing out from evaporimeter 4, gets back to compressor 1, accomplishes the circulation that heats of system.When system compresses machine 1 exhaust outlet (high pressure) and compressor 1 air entry (low pressure) pressure reduction are very big; Controller control electromagnetism two-port valve 5 is opened; At this moment, cold-producing medium has reached the purpose of compressor 1 high-low pressure balance rapidly through electromagnetism two-port valve 5 these latus rectums, has effectively improved system effectiveness.
When environment temperature is very low; Unit is in heating process, and the frosting phenomenon will appear in evaporimeter 4, controller 6 control electromagnetism two-port valves 5 conductings this moment; The gas of the HTHP that compressor 1 is discharged will pass through electromagnetism two-port valve 5 and be bypassed to evaporimeter 4, gets back to the return-air mouth of compressor 1 then.The gas of HTHP flows through from electromagnetism two-port valve 5, directly gets into evaporimeter 4, discharges heat to evaporimeter 4, and the frost on the evaporimeter 4 will melt away, and reaches the purpose of defrosting.Do like this, not only avoided compressor 1 frequently to stop machine and defrosted, and reduced the energy consumption of unit, improved the efficient of unit.
