Specific embodiment
As shown in Figure 1, the present embodiment is double-compressor heat pump unit and its system, one is invariable frequency compressor 7, another
It is frequency-changeable compressor 1, the circulating pump on heat source tower anti-icing fluid circulating pump 13 and warm matchmaker's waterpipe 14 works as heat prior to compressor start
Electric heating starting first preheats refrigeration oil before pump assembly prepares operation, when preheating makes refrigeration oil reach suitable temperature, frequency conversion pressure
Contracting machine 1 starts in advance, starts invariable frequency compressor 7 after reaching power frequency, then it is cold to be just compressed into segmented shell-and-tube for refrigerant
In the shell of condenser 15 after warm matchmaker's water heat absorption in the condenser tube side, refrigerant release latent heat is become as liquid refrigerant,
Angle valve 17 and gs-oil separator 16 must be gone out by refrigerant before entering segmented shell-and-tube cooler 15, refrigerant goes out angle valve
17 and refrigerant into angle valve 2 be applied not only to adjusting refrigerant flow rate, and while can be used for repairing unit, lets out convenient for saving refrigerant
Leakage；The effect of gs-oil separator 16 both can prevent refrigeration oil from entering segmented shell-and-tube cooler 15 and influencing heat transfer effect,
It is also simultaneously a kind of grease interceptor, and refrigeration oil can be made to be back in compressor by pressure difference, in this way, saving refrigeration oil can be played
Unit efficiency effect is improved, because refrigeration oil, which is excessively more than, increases cost problem, and condensation and evaporating space can be occupied
Influence unit efficiency problem；Just pass through air-supplying enthalpy-adding device after 15 inner refrigerant of segmented shell-and-tube cooler discharges latent heat
Expansion throttling device 4 is flowed through further through corresponding pipeline after 5 components, which can be by heating power expansion valve and electrically-controlled valve
It is formed, is finally entered back into combined type dry evaporator 6, refrigerant side of flowing through in told combined type dry evaporator 6
Formula is: liquid phase refrigerant enters acquisition anti-icing fluid part latent heat inside low portion tubulation and just forms gas-liquid two-phase fluid, then,
It enters back into high-order portion tubulation and obtains more anti-icing fluid latent heat, in this way, refrigerant can be inhaled into change after substantially completely evaporating
Frequency compressor 1 and the inside of invariable frequency compressor 7, and add Siphon pot 3 then between combined type dry evaporator 6 and compressor and be because
The refrigeration oil to come from segmented shell-and-tube cooler 15 is in a liquid state form at low temperatures, when refrigeration oil is in combined type
6 tube side inner accumulation of dry evaporator to a certain extent after just blocked coolant channel, cause unit to be unable to operate normally.Only
Solve the problems, such as that liquid hammer and oil are stifled, refrigerant could recycle again and again well, pass through by refrigerant phase transformation mode
Anti-icing fluid enters heat source tower pipeline 9 and constantly from anti-icing fluid to air asks for low-temperature heat source by steam energy heat source tower 10 and by heat pump master
Machine is transferred to heat at high temperature, and the anti-icing fluid for passing through steam energy heat source tower 10 is constantly pumped into host by anti-icing fluid circulating pump 13
Go release latent heat to refrigerant inside evaporator, this just forms anti-icing fluid cyclic process, however anti-icing fluid is crossing steam energy heat
Heat has been carried out with upstream air when the tower 10 of source to exchange, and constantly obtains the sensible heat of air, while also obtaining air
In steam latent heat, be condensed water dilution so as to cause antifreeze liquor, amount of solution increases, and can also cause freezing point of solution temperature
Degree moves up, and the copper pipe of solution icing and swollen bad evaporator eventually occurs, so must be equipped with anti-icing fluid solution condensing device 11,
Immediately starting solution condensing device 11, solution concentration it can finish and can be pumped by solution pump 12 after amount of solution increases and reaches a certain level
It goes in 6 anti-icing fluid pipeline of combined type dry evaporator.Heat of low-temperature heat source is transferred to warm matchmaker's water eventually by heat pump main frame, and
Warm matchmaker's waterpipe 14 by leading to user is conveyed to user.When refrigeration oil operating temperature is excessively high, then the cooling dress of refrigeration oil is needed
8 are set to cool down for it.
Its flowage structure of the invention patent is not limited to the embodiment, and structure type can be various, it is prior to twin-screw
Compressor, although evaporator and condenser are all shell-and-tube heat exchangers, evaporator must use suitable low temperature environment being capable of pole
The dry type Steaming structure for preventing liquid hammer event from occurring greatly.The cooling device especially treated for refrigeration oil.There are also angle valves to match
Setting is also a special point, its comprehensive above-mentioned the invention patent is not the combination for being simple multiple technologies, and maximum is intended to this
Heat pump unit is equipped with steam energy heat source tower and combines anti-icing fluid solution condensing device, and the system equipment device can be made to adapt to
The good operation of low temperature environment, operating condition can obtain preferable economy.
