Abstract
The invention provides a device for protecting a compressor of a heat pump water heater, which comprises the compressor, an expansion valve, an evaporator and a condenser. The compressor, the expansion valve, the evaporator and the condenser are respectively communicated with each other by copper pipes, the condenser is connected with a first movement stopping valve and the expansion valve by copper pipes, the expansion valve is parallelly connected with a first pressure relief valve, and the evaporator is connected with a second movement stopping valve and the compressor by copper pipes. Opening and closing states of the movement stopping valves are controlled by a microcomputer, refrigerant is limited in the copper pipes, and after the heat pump water heater is stopped, the problem that refrigerant in the condenser moves into the evaporator and the compressor to cause hydraulic impact on the compressor after the compressor is restarted is prevented.
Description
Technical field
The present invention relates to the Teat pump boiler aspect, particularly relate to a kind of protection Teat pump boiler compressor set.
Background technology
Teat pump boiler is the device that utilizes a kind of efficient heat-collecting of contrary Carnot's principle and shift heat; The water storage type water heater that goes out concrete application as shown in Figure 1; Through driving heat pump with electric energy, to form by critical pieces such as the compressor 1 ' in the heat pump assembly, expansion valve 2 ', evaporimeter 3 ', condensers 4 ', compressor 1 ' sucks the low-temp low-pressure gas refrigerant from evaporimeter 3 '; Through the electricity consumption acting cold-producing medium is compressed into high temperature and high pressure gas; High temperature and high pressure gas gets into condenser 4 ' and water heat-shift, in condenser 4 ', is condensed into cryogenic liquid and discharges great amount of heat, and water absorbs its heat that discharges and temperature constantly rises; The high pressure low temperature liquid that is condensed is after expansion valve 2 ' throttling step-down; In evaporimeter 3 ', absorb ambient substance (air, water and soil earth) thus heat evaporate into low-pressure gas, be inhaled in the compressor again and compress, such circulation repeatedly and produce hot water.
When the water temperature in the water tank (condenser 4 ') reached setting value, compressor 1 ' quit work, and water tank has insulation effect, then comparatively fast was cooled to equate with the temperature of environment for evaporimeter 3 ' and compressor 1 '.When there is temperature contrast in the long period between condenser 4 ' and the evaporimeter 3 '; Cold-producing medium in the condenser 4 ' will constantly evaporate moves to evaporimeter 3 ' and compressor 1 ' middle cooling; The cold-producing medium of this process in condenser 4 ' evaporates fully and cooled off; But the consequence of this refrigerant migration as easy as rolling off a logly forms liquid hammer when causing compressor 1 ' to start once more and compressor 1 ' damage.
Summary of the invention
For solving the above-mentioned liquid hammer problem that causes compressor when starting once more, to be suffered because of refrigerant migration,, resistance moves flowing of valve restrict refrigerant through being set.
Therefore; The present invention includes compressor, expansion valve, evaporimeter, condenser that copper pipe is communicated with respectively; Wherein, Said condenser moves valve through copper pipe connection first resistance and is connected with said expansion valve, and said expansion valve also is connected to a relief valve, and said evaporimeter moves valve through copper pipe connection second resistance and is connected with said compressor.
Wherein, said first resistance is moved valve and is electrically connected first microcomputer, and said second resistance is moved valve and is electrically connected second microcomputer.
It is identical that valve is moved in said first resistance, valve arrangement is moved in second resistance; Be provided with the valve body that is connected with copper pipe in it, be provided with cavity in the said valve body, be provided with valve plug movable up and down in the said cavity; The top of said valve plug is provided with armature, and said armature is to contact with the magnetic device at cavity top is movable.
Be provided with thrust spring between said valve plug and the magnetic device.
Beneficial effect of the present invention is that condenser moves valve through copper pipe connection first resistance and is connected with said expansion valve; This first resistance is moved valve and is electrically connected first microcomputer; Said expansion valve also is connected to a relief valve, and said evaporimeter moves valve through copper pipe connection second resistance and is connected with said compressor, and this second resistance is moved valve and is electrically connected second microcomputer; Move the Push And Release state of valve through the system controlled by computer resistance; Cold-producing medium is limited in the copper pipe, effectively stop Teat pump boiler to be shut down after, the refrigerant migration in the condenser is moving in evaporimeter and compressor and cause compressor in the liquid hammer problem that starts once more afterwards compressor.
Description of drawings
Fig. 1 is a conventional heat pump water heater sketch map;
Fig. 2 is a sketch map of the present invention;
Fig. 3 moves the cutaway view that valve is in closed condition for the cold-producing medium resistance;
Fig. 4 moves the cutaway view that valve is in open mode for the cold-producing medium resistance.
The specific embodiment
In conjunction with accompanying drawing and the present invention is done further as shown in Figure 2, the compressor 1 that copper pipe 5 is communicated with respectively, expansion valve 2, evaporimeter 3, condenser 4, wherein; Said condenser 4 moves valve 6 through copper pipe 5 connections first resistance and is connected with said expansion valve 2; Said expansion valve 2 also is connected to a relief valve 21, and said evaporimeter 3 moves valve 7 through copper pipe 5 connections second resistance and is connected with said compressor 1, wherein; Said first resistance is moved valve 6 and is electrically connected first microcomputer 61, and said second resistance is moved valve 7 and is electrically connected second microcomputer 71.
Otherwise, "on" position as shown in Figure 4, valve body 62 is attracted by magnetic device 65 together with armature 64, breaks away from the elastic force of thrust spring 66 and makes and be communicated with in the copper pipe 5, forms open mode.
Therefore; The state of valve through its Push And Release of system controlled by computer moved in resistance, and cold-producing medium is limited in the copper pipe, effectively stop Teat pump boiler to be shut down after; Refrigerant migration in the condenser 4 causes compressor 1 starting the liquid hammer problem of back to compressor 1 once more in evaporimeter 3 and compressor 1.
And after the microcomputer controller of Teat pump boiler is received shutdown command; Two cold-producing mediums resistances is moved valve prior to closing for 3 seconds, and the cold-producing medium in the cut-off system can not two-way flow, and then close compressor 1;, open the cold-producing medium resistance again and move valve then for driving compressor 1 earlier for boot program.
