Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of ultralow temperature taken into account refrigeration and heating and stablized
Cooling-and-warming heat pump system.
To achieve the above object, a kind of ultra-low temperature cold warm heat pumping system provided by the utility model, wherein, including compression
Machine, the condenser connected with four-way valve, the increasing enthalpy magnetic valve being respectively communicated with condenser and hydrojet magnetic valve and increasing enthalpy magnetic valve
The increasing enthalpy expansion valve of connection, the economizer connected respectively with increasing enthalpy expansion valve and compressor, respectively with hydrojet magnetic valve and compression
Machine connection hydrojet capillary, connected with economizer reservoir, be provided between economizer and reservoir refrigeration expansion valve,
In the coconnected evaporator of reservoir, the filter being provided between reservoir and evaporator, and in filter and evaporator
Between be provided with the heating expansion valve that is connected with refrigeration expansion valve.It is respectively arranged between reservoir and process device and evaporator unidirectional
Valve.Gas-liquid separator is provided between compressor and four-way valve.
The beneficial effects of the utility model are that have to take into account refrigeration and heating and stable effect.Due to using one in structure
Individual air injection enthalpy-increasing expansion valve, a heating expansion valve, a refrigeration expansion valve.By the steering of check valve, when heating just
Use air injection enthalpy-increasing expansion valve and heating expansion valve.Refrigeration expansion valve is just used when refrigeration, is so separately controlled, is separately adjusted
Section, make heating and refrigeration can stable operation.Solves stability and Energy Efficiency Ratio that source pump is run in winter ultralow temperature
Difference and the stability and Energy Efficiency Ratio of cooling in summer are poor, on the basis of having air injection enthalpy-increasing technology, increase kind of refrigeration cycle, make heat pump
In the stability and Energy Efficiency Ratio that winter and summer can obtain.The system that ultralow temperature heating and cooling in summer can be taken into account,
And higher stability and Energy Efficiency Ratio can be obtained.Realize to have and take into account refrigeration and heating and stable effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of ultra-low temperature cold warm heat pumping system, including compressor 1, connected with four-way valve 14 condenser,
The increasing enthalpy magnetic valve 10 and hydrojet magnetic valve 11 that are respectively communicated with condenser, the increasing enthalpy expansion valve 9 connected with increasing enthalpy magnetic valve 10,
The economizer 15 connected respectively with increasing enthalpy expansion valve 9 and compressor 1, the spray connected respectively with hydrojet magnetic valve 11 and compressor 1
Liquid capillary 13, the reservoir 7 connected with economizer 15, the refrigeration expansion valve 8 being provided between economizer 15 and reservoir 7,
In the coconnected evaporator 3 of reservoir 7, the filter 6 being provided between reservoir 7 and evaporator 3, and filter 6 with
The heating expansion valve 5 connected with refrigeration expansion valve 8 is provided between evaporator 3.Divide between reservoir 7 and process device and evaporator 3
Check valve 4 is not provided with.Gas-liquid separator 2 is provided between compressor 1 and four-way valve 14.
Using when, use an air injection enthalpy-increasing expansion valve 9, two heating expansion valves 5, a refrigeration expansion valve 8 in structure.
By the steering of check valve 4, just using air injection enthalpy-increasing expansion valve 9 and heating expansion valve 5 when heating.Just make when refrigeration
With refrigeration expansion valve 8, so it is separately controlled, separate regulation, makes heating and refrigeration can stable operation.Solves source pump
It is poor in the stability and Energy Efficiency Ratio difference and the stability and Energy Efficiency Ratio of cooling in summer of the operation of winter ultralow temperature, there is air injection enthalpy-increasing
On the basis of technology, increase kind of refrigeration cycle, the stability and Energy Efficiency Ratio for heat pump has been obtained in winter and summer.Can
The system of ultralow temperature heating and cooling in summer is taken into account, and higher stability and Energy Efficiency Ratio can be obtained.
Heating circulation theory is：The compression that the gas coolant of HTHP passes through compressor 1.Into four-way valve, pass through four
The commutation of port valve is condensed into condenser 12, and by three tunnels of condensing heat-exchange point, the first via is by increasing enthalpy magnetic valve 10 and increases
Enthalpy expansion valve 9 enters economizer 15, and return to the increasing enthalpy mouth of compressor 1 after being evaporated in the inside of economizer 15 circulates for tonifying Qi.When
When delivery temperature is more than 102 degree, the second road refrigerant reaches the increasing enthalpy mouth of compressor 1 from hydrojet magnetic valve 11 and hydrojet capillary 13
Circulated for hydrojet, increase refrigerant circulation, reduced delivery temperature and improve heating capacity.3rd road carries out secondary cold into economizer 15
It is solidifying, reservoir 7 is entered back into, is throttled by filter 6 and heating expansion valve 5, evaporator 3 is entered back into and is evaporated heat absorption again
Return to compressor 1 and complete heating circulation, by adjusting the heating degree of superheat of expansion valve 5 heating can be made to reach optimum efficiency, and surely
Fixed operation.
Kind of refrigeration cycle principle is：The gas coolant of HTHP is carried out cold by the compression of compressor 1 into evaporator 3
It is solidifying, then throttled by reservoir 7, filter 6 and refrigeration expansion valve 8, enter back into condenser 12 and be evaporated, return compressor
1, refrigeration can be made to reach optimal by adjusting the degree of superheat of refrigeration expansion valve 8, and stable operation.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to practical new
The protection domain of type.
