(2) technical background
The water heater of generally selling has electric heater, gas heater, solar water heater etc. in the market, wherein, electric heater is a cost with the electric energy that consumes a large amount of costlinesses, be unfavorable for the reasonable utilization of the energy, in use then there is serious potential safety hazard in gas heater, and report is arranged during the annual poisoning that causes because of the use of gas heater; Conventional solar water heater can not be produced hot water overcast and rainy, can only rely on electrical heating to remedy the deficiency of solar energy, thereby the wasting phenomenon that has the energy particularly uses this water heater very uneconomical at some overcast and rainy southern areas of Duoing than effect.So, a kind of novel water heater based on the heat pump cycle principle begins to show up prominently on water heater market, it is to utilize evaporimeter to absorb heat energy (solar energy, air or water etc.) from surrounding environment, and by condenser heat energy is discharged into and goes in the water tank, thereby produces hot water.That Teat pump boiler has is energy-efficient, can round-the-clockly use, advantage such as safe and reliable, and has realized the rudimentary utilization of the energy, has wide development and application prospect.
The air source water heater of domestic production at present and sale designs and processes by air-conditioning heating condition in winter.When these Teat pump boilers move under summer condition, cold-producing medium evaporating temperature (pressure) can raise along with the rising of outside air temperature, and adopt single capillary to be connected between condenser and the evaporimeter, its open degree is fixing nonadjustable, quality and the flow that flows into the cold-producing medium of evaporator with heat pump can reduce like this, the compressor air suction degree of superheat increases, and then influence the volumetric efficiency and the electric efficiency of compressor, make compressor exhaust temperature and high pressure exceed the compressor operating scope, cause the compressor can't operate as normal; And under the weather of severe cold, the capillary open degree is too big again, and low pressure is higher, can not absorb enough air heat energies, causes Energy Efficiency Ratio very low.This shows, can not satisfy the needs of whole year operation operating mode fully by the capillary open degree of air-conditioning heating condition in winter design, make that not only the annual heating performance coefficient of air source hot pump water heater is difficult to improve, and to producing safety, stable operation and actual life of compressor harmful effect.
(3) summary of the invention
Adopt single capillary to be connected the problems referred to above of being brought between the condenser that solves existing air source water heater and the evaporimeter, the utility model proposes the self-adjustable air source water heater of a kind of capacity, can effectively solve system matches and capacity regulating problem in the Teat pump boiler whole year operation, the coefficient of performance and economic performance under the different temperature of raising system.
A kind of capacity step-less adjustment air source water heater comprises evaporimeter, and the outlet of evaporimeter connects the inlet of gas-liquid separator, and the outlet of gas-liquid separator connects the air inlet of air compressor, and the exhaust outlet of air compressor connects the condenser inlet in the water tank; The outlet of described condenser connects the inlet of described evaporimeter by heating power expansion valve, the temperature-sensitive bag of described heating power expansion valve is attached on the inlet tube wall of described gas-liquid separator, and the pressure-equalizing pipe of described heating power expansion valve is connected with the inlet tube of described gas-liquid separator.
Further, described condenser is the spiral condenser coil that is arranged on described water tank bottom.
Technical conceive of the present utility model is: be connected with the inlet of evaporimeter by the outlet of heating power expansion valve with condenser, the open degree that the heating power expansion valve of band temperature-sensitive bag and pressure-equalizing pipe can come variable expansion valve according to the evaporator outlet refrigerant vapour degree of superheat and the pressure of detection, when refrigerant vapour is overheated, temperature-sensitive coating sheet expands, the open degree of expansion valve increases, thereby makes the liquid refrigeration agent flux increase that passes back into evaporimeter from condenser; When the refrigerant vapour temperature is crossed when low, temperature-sensitive coating sheet shrinks, and the open degree of expansion valve reduces, and makes to reduce from the liquid refrigeration agent flux of condenser inflow evaporator, realize stepless throttling regulatory function, make evaporimeter under the operating mode of different temperature, can obtain rational air-energy.
The beneficial effects of the utility model show: (1) adopts heating power expansion valve to control open degree automatically, can greatly improve the coefficient of performance and annual economical operation performance under the air source hot pump water heater varying environment temperature; (2) air compressor is stable, and improve service life.
