Heat pump water heater technology is the new energy technology receiving much attention in the whole world in recent years." heat pump " as its name suggests, is exactly a kind of pump of carrying " heat energy ", it can draw abundant low grade heat energy from natural air, water or soil, through electric power acting, the device of the high-grade heat energy used of behaving is provided, its essence is to heat and use compressor.In actual use, many times, heat pump need to be worked under 0 DEG C of low ambient temperature below even-15 DEG C, therefore can produce following problem: the one, and along with the decline of ambient temperature, heating capacity is progressively decay also.The aspirated volume of compressor is certain, and air-breathing mass flow rate can reduce along with sucking the decline of refrigerant density.The density of the refrigerant saturation temperature corresponding with it has relation one to one, and the density of the higher refrigerant of saturation temperature is also lower.Along with the decline of ambient temperature, the refrigerant mass flow rate that compressor sucks is fewer, makes the refrigerant minimizing of condenser of flowing through, thereby can not effectively utilize the heat exchange area of condenser, and the heating capacity of unit and COP can decay rapidly.The 2nd, because gettering quantity diminishes, refrigerant cannot be taken away rapidly the unnecessary heat of compression chamber, makes compression chamber excess Temperature, produces the problem of reliability aspect.
At present, common solution is to increase electrical auxiliary heater, and what compensation low temperature environment brought heats not enough problem, but this scheme is not energy-conservation, and comprehensive COP is low, and can not solve the problem of overheat of compressor, because of instead of a ultimate solution, do not recommend.
Model utility content
The object of the invention is to propose a kind of hyperbaric chamber and spray increasing enthalpy scroll compressor, it is a kind of accurate two stage compressor, can effectively improve heating capacity and the reliability of compressor.
Hyperbaric chamber sprays and increases enthalpy scroll compressor, there is a housing, scroll compressor assembly is installed in housing, scroll compressor assembly comprises frame, fixed scroll, motion vortex dish, bent axle and motor, erecting central authorities axis hole, on the central axis hole of frame, bearing is installed, fixed scroll is installed in the top of frame, motion vortex dish is placed between fixed scroll and frame, fixed scroll and motion vortex dish form scroll compression chamber, bent axle is through central axis hole and the bearing of frame, the eccentric part on bent axle top inserts in the excentric sleeve of motion vortex dish, the bottom mounting rotor of electric motor of bent axle, motor stator is fixedly mounted on the below of frame, fixed scroll has scroll suction port and scroll relief opening, housing top is connected with compressor inleting pipe, compressor inleting pipe is through housing, its inner port is connected in scroll suction port, scroll relief opening is communicated with scroll compression chamber with the interior space of housing, housing middle part is connected with compressor exhaust pipe, outlet pipe is for being connected compressor with the condenser portion of refrigeration system, discharge the later refrigerant of compression.
In addition, other being processed with of scroll relief opening of fixed scroll sprayed increasing enthalpy hole, the position that the corresponding injection of shell increases enthalpy hole is processed with coolant injection increasing enthalpy pore, coolant injection increases enthalpy pipe end and is directly inserted in the injection increasing enthalpy hole of fixed scroll through coolant injection increasing enthalpy pore, makes coolant injection increase enthalpy pipe and is communicated with the scroll compression chamber in fixed scroll.
Feature of the present utility model is as follows:
One, while using the utility model, increasing enthalpy pipe by coolant injection flows through the refrigerant in systemic circulation after condenser condenses, there is part refrigerant (can be liquid coolant or gas coolant according to the needs of system applies) to increase enthalpy loop through spraying, according to the control of coolant injection control system, refrigerant is directly injected to the middle scroll compression chamber being formed by fixed scroll and motion vortex dish, compressor carries out secondary compression to it, so just, can maximally utilise the actual volume of compressor, improve compressor air suction mass flow rate, thereby reach the object of raising system heating capacity.
Two, because the refrigerant spraying is to be directly injected to middle scroll compression chamber, refrigerant can play cooling scroll, reduce the effect of delivery temperature, thereby has also improved compressor reliability.
