Abstract
The invention discloses an air conditioner heat pump water heater with improved structure, which comprises a compressor (1), a cross joint reversing valve (6), an outdoor heat exchanger (7), an indoor heat exchanger (2), a throttle pipe (10), a water storage tank (4) and a connecting pipeline (3), and is provided with an automatic variation system that can increase or reduce the running of a refrigerating agent in the connecting pipeline (3) by a lower limit water temperature signal and an upper limit water temperature signal detected by a water temperature probe (5) of the water storage tank. The air conditioner heat pump water heater with improved structure can adapt to external climate change and water temperature change in the water storage tank, avoid overload mechanical accident due to system running that is caused by super-high water temperature and inadequate liquid supply that is caused by super-low water temperature, and can enlarge the feasible running environmental temperature of a machine set, thus improving the running quality of the machine set, being favorable to maintaining the running stability of the machine set, ensuring the normal effect of energy efficiency ratio, and prolonging the service life of the machine set.
Description
Technical field
The present invention relates to a kind of air-conditioner heat pump water heater that improves structure, belong to the technical field that household electrical appliance are made.
Background technology
Split-type air conditioner hot water unit mainly is made up of assemblies such as comprising compressor, four-way change-over valve, outdoor heat converter, indoor heat converter, throttle pipe, water storage tank and connecting line.Because split-type air conditioner hot water unit is subjected to the influence of self and external environment condition, the irregular variation of water temperature, temperature, can occur crossing low feed flow (cold-producing medium) deficiency or the too high overload mechanical accident that causes system's operation of water temperature because of water temperature, therefore directly have influence on the running quality of unit, the poor stability of unit operation, the performance of Energy Efficiency Ratio is undesired, and service life is short etc.
Summary of the invention
Of the present invention providing a kind ofly adapts to the irregular variation of water temperature, temperature and guarantees the air-conditioner heat pump water heater of running quality.
A kind of air-conditioner heat pump water heater that improves structure provided by the invention, comprise compressor, four-way change-over valve, outdoor heat converter, indoor heat converter, throttle pipe, water storage tank and connecting line, can increase or reduce the automatic variable system that cold-producing medium moves in connecting line by pop one's head in detected lower limit water temperature signal or upper limit water temperature signal of the water temperature of water storage tank thereby be provided with.
Described automatic variable system comprises the variable jar that is used to store cold-producing medium, the import of variable jar is connected between throttle pipe and the outdoor heat converter through inlet valve, outlet connects compressor through outlet valve, and described inlet valve, outlet valve are controlled by the water temperature probe of water storage tank respectively.
Throttle capillary tube is arranged respectively before the inlet of inlet valve and outlet valve.
The present invention is owing to increased the automatic variable system that cold-producing medium moves in connecting line in system, can adapt to the variation of outside weather and the variation of the interior water temperature of water storage tank like this, avoid water temperature too high and overload mechanical accident and water temperature that cause system operation to cause are crossed low and the feed flow deficiency, the environment temperature that unit can be adapted to operation enlarges, thereby can improve the running quality of unit, help keeping the stability of unit operation, the normal performance that keeps Energy Efficiency Ratio, the service life of prolongation unit.In addition, be that the operation of participation system is to utilize interior can the going of operating compressor to realize because the cold-producing medium of variable jar increases or reduces, therefore do not need other consumed power.
Description of drawings
Fig. 1 is a structure principle chart of the present invention.
The specific embodiment
With reference to Fig. 1, a kind of air-conditioner heat pump water heater that improves structure that the present invention carries, comprise compressor 1, four-way change-over valve 6, outdoor heat converter 7, indoor heat converter 2, throttle pipe 10, water storage tank 4 and connecting line 3, can increase or reduce the automatic variable system that cold-producing medium moves in connecting line 3 by pop one's head in 5 detected lower limit water temperature signals or upper limit water temperature signal of the water temperature of water storage tank thereby be provided with.Lower limit water temperature or upper limit water temperature can be decided according to realization needs or each ground temperature situation.
Described automatic variable system comprises the variable jar 11 that is used to store cold-producing medium, the import of variable jar 11 is connected between throttle pipe 10 and the outdoor heat converter 7 through inlet valve 8, outlet connects compressor 1 through outlet valve 12, inlet valve 8, outlet valve 12 are magnetic valve or motor-driven valve, are controlled by the water temperature probe 5 of water storage tank respectively.Be equiped with screen pack in this variable jar 11, have any impurity to enter compressor 1 when preventing to move.
Before the inlet of inlet valve 8 and outlet valve 12, throttle capillary tube 9 is arranged respectively.
During use, when the water temperature in the water storage tank 4 is low, water temperature probe 5 detects the lower limit water temperature signal, by control circuit the outlet valve 12 of variable jar 11 is opened, inlet valve 8 is in closed condition, is stored in cold-producing medium in the variable jar 11 and enters compressor 1 by throttle capillary tube 9, throttle capillary tube 9 and participate in cold-producing medium and move connecting line 3 in, and the interior water absorption heat of water storage tank 4 is many, indoor heat converter 2 evaporation capacity strengthen, and make intrasystem efficiency perform to maximum, the most stable.
When the water temperature in the water storage tank 4 is higher, water temperature probe 5 detects upper limit water temperature signal, by control circuit outlet valve 12 cuts out, the inlet valve 8 of variable jar 11 is opened, cold-producing medium is extruded by throttle capillary tube 9, inlet valve 8 and is recovered in the variable jar 11, reducing cold-producing medium moves in connecting line 3, adjust the best operating point of compressor and system operation, effectively avoid causing system to move the overload mechanical accident that HTHP causes, guaranteed the stability of system's operation effectively because of water temperature is too high.
