Description
Technical field
The present invention relates to a kind of hot water machine, particularly a kind of air source heat pump circulation/single flow hot water machine.
Background technology
Traditional business PC main flow has circulator and directly-heated circulator two big classes, its operation principle as shown in Figure 1, the heating unit method of operation: the steam of compressor suction condition 1 is closed the state of being compressed to 2; State 2 closed compression are discharged state 3 HTHP gaseous states; State 3 changes state 4 high-pressure liquids into after condensation; State 4 changes state 4 ' low-pressure low-temperature liquid state into through throttling; State 4 ' draw the steam that air themperature becomes state 1 through evaporimeter; So periodic duty; Water mode of heating: directly drive water and in the unit condenser, circulate, carry out heat exchange, water temperature is constantly heated up, until being heated to design temperature with water pump.Because the working environment of traditional circulator and directly-heated circulator has not just had the advantage of heat production water all-7 ℃～43 ℃ scope when therefore most of air source unit is lower than-5 ℃, when operating ambient temperature can't operate as normal during at-20 ℃.At this technical difficult problem, the applicant releases the air-source heat pump hot water that hydrojet increases enthalpy, this hydrojet increase the air-source heat pump hot water of enthalpy can be under-20 ℃ of environment temperatures operate as normal.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the air-source heat pump hot water that a kind of hydrojet increases enthalpy, this hydrojet increase the air-source heat pump hot water of enthalpy can be under-20 ℃ of environment temperatures operate as normal.
The technical solution adopted for the present invention to solve the technical problems is:
Hydrojet increases enthalpy air source heat pump circulation/single flow hot water machine, the heating unit that comprises water tank, forms by compressor, the condenser that is connected with compressor and evaporimeter, condenser is connected with evaporator pipeline, water tank is connected with condenser with inlet channel by outlet conduit, on the outlet conduit of water tank, water pump is installed, it is characterized in that being connected with a lateral on the connecting pipe of condenser and evaporimeter, described lateral is connected with the working chamber of compressor.
The magnetic valve and first expansion valve are installed on the described lateral.
Second expansion valve is installed on the connecting pipe of described condenser and evaporimeter.
On the described water tank outlet conduit valve and check-valves are installed.
On the described water tank outlet conduit moisturizing pipeline is installed, moisturizing magnetic valve and water regulating valve are installed on the moisturizing pipeline, occur hot and cold water when preventing moisturizing and mix the water phenomenon, avoid causing the hot water water temperature that has heated acutely to descend.
The invention has the beneficial effects as follows: heating capacity almost is the trend of linear growth with the relative complement atmospheric pressure, when other condition is constant, the relative complement atmospheric pressure becomes the increase that means air compensation greatly, increase air compensation and not only make refrigerant flow increase in the condenser, and the power consumption of compressor is increased, the two all can increase the thermic load of system, and promptly the unit heating capacity has increased; And the coefficient of performance of the present invention changes very little with the relative complement atmospheric pressure; Compressor exhaust temperature raises with the relative complement atmospheric pressure and obviously reduces, and therefore increases air compensation and can improve compression process and help to reduce delivery temperature, to guarantee operate as normal under-20 ℃ of environment temperatures, guarantees the reliability of compressor operating.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the schematic diagram of existing air source heat pump circulation/single flow hot water machine;
Fig. 2 is a schematic diagram of the present invention.
The specific embodiment
With reference to Fig. 2, hydrojet disclosed by the invention increases enthalpy air source heat pump circulation/single flow hot water machine, comprise water tank 6, by compressor 7, the heating unit that condenser 8 that is connected with compressor 7 and evaporimeter 9 are formed, condenser 8 is connected with evaporimeter 9 pipelines, on the connecting pipe of condenser 8 and evaporimeter 9 second expansion valve 14 is installed, water tank 6 is connected with condenser 8 with inlet channel 11 by outlet conduit 10, on the outlet conduit 10 of water tank 6, water pump 12 is installed, valve 15 and check-valves 16, on the connecting pipe of condenser 8 and evaporimeter 9, be connected with a lateral 13, this lateral 13 is connected with the working chamber of compressor 7, and the magnetic valve 20 and first expansion valve 21 are installed on lateral.
It is to set up two symmetrical gas supplementing opening (not shown)s in the intermediate compression chambers of former common type that hydrojet of the present invention increases enthalpy hot pump in low temp compressor, and above-mentioned lateral is connected with this gas supplementing opening.
As shown in Figure 2, on the outlet conduit 10 of water tank 6, moisturizing pipeline 17 is installed also, moisturizing magnetic valve 18 and water regulating valve 19 are installed on the moisturizing pipeline 17, occur hot and cold water when preventing moisturizing and mix the water phenomenon, avoid causing the hot water water temperature that has heated acutely to descend.
Operation principle of the present invention is:
A, the heating unit method of operation:
1, the steam of compressor suction condition 1 is closed the state of being compressed to 2;
2, original gas of chamber internal state 2 mixes with state 5 gases that enter the compressor operating chamber by the gas supplementing opening that is connected with lateral 13, compress while mixing with the back tonifying Qi, break away from until working chamber and gas supplementing opening, at this moment the state 2 of the gaseous state in the working chamber before by tonifying Qi become state 2 after the tonifying Qi ';
3, after working chamber and gas supplementing opening broke away from, the gas in it was from state 2 ' the be closed state of being compressed to 3.
B, water mode of heating:
1, when unit receives the moisturizing signal, the moisturizing valve opening solenoid, water pump quits work, and running water directly is heated to set water temperature to attemperater from thermostatted water adjustable valve regulating pondage through condenser.Advantage is not mix water, increases water consumption.
2, when machine group of received high water level signal, the moisturizing magnetic valve closes, and water pump leaves, and carries out heated at constant temperature.
Heating capacity of the present invention almost is the trend of linear growth with the relative complement atmospheric pressure, when other condition is constant, the relative complement atmospheric pressure becomes the increase that means air compensation greatly, increase air compensation and not only make refrigerant flow increase in the condenser, and the power consumption of compressor is increased, the two all can increase the thermic load of system, and promptly the unit heating capacity has increased; And the coefficient of performance of the present invention changes very little with the relative complement atmospheric pressure; Compressor exhaust temperature raises with the relative complement atmospheric pressure and obviously reduces, and therefore increases air compensation and can improve compression process and help to reduce delivery temperature, guarantees the reliability of compressor operating.
