Abstract
The invention discloses an antifreezing control method for a hot water heater of an air conditioning heat pump. The method comprises the following steps of: collecting water temperature values of a water system of a unit of the hot water heater of the air conditioning heat pump at to-be-detected parts in a water circulating pipeline; and when the water temperature value at any one of the to-be-detected parts is smaller than a corresponding set temperature value, starting an auxiliary heating device at a corresponding part so as to raise the temperature of the part and the water temperature of the water system. The method disclosed by the invention can solve the problem that the hot water heater of the air conditioning heat pump is frozen as parts of the water system are frozen due to over-low water temperature in the water system.
Description
Technical field
The present invention relates to air-conditioning technical field, more particularly, to a kind of air conditioner heat pump hot water and its antifreeze control method.
Background technology
In Central China, North China and Northeast Regional, because winter makes outdoor ambient temperature is relatively low, sometimes even up to water freezing point with
Under.Under such low temperature environment, the unit of air conditioner heat pump hot water did not used or due to a variety of causes for a long time in winter
And under short time powering-off state, if discharging water in unit water system in time and unit is standby and water of in water system does not flow
Dynamic, then each part that can lead to unit water system is (as water-side heat, water circulating pump water flow switch, water charging system, differential water pressures are held
Close etc.) inner icing and freezing.
When being in summer, when the unit of air conditioner heat pump hot water is in refrigeration mode, lead if water system design is lack of standardization
Cause discharge less than normal, or unit is led to due to abnormal phenomena leaving water temperature too low in use and induces each portion of water system
When part freezes, then occur that water system and coolant media system mutually immerse and the phenomenon of disorderly closedown, thus reducing user's body
Test.
Content of the invention
Present invention is primarily targeted at providing a kind of air conditioner heat pump hot water and its antifreeze control method it is intended to solve empty
Adjust heat pump water-heating machine too low because of the water temperature in water system, and the problem that freezing and freezing occur in each part of water system leading to.
For achieving the above object, the present invention provides a kind of antifreeze control method of air conditioner heat pump hot water, walks including following
Suddenly：
Water temperature value at S1, unit water system part to be detected in water circulation pipe of collection air conditioner heat pump hot water；
S2, it is less than corresponding set temperature value when the water temperature value at any one part to be detected is detected, then start corresponding
Assisted heating device at part, to improve the temperature of this part and the water temperature of water system.
Preferably, the described water temperature value detecting at any part of working as is less than corresponding set temperature value, then start phase
Answer the assisted heating device at part, with improve the temperature of this part and the water temperature of water system step after also include：
Obtain the heat time heating time of described assisted heating device；
When being more than the predetermined heat time described heat time heating time, if detect water temperature value at any part still less than
Corresponding set temperature value, then control described air conditioner heat pump hot water to open water pump, so that static water in described water system follows
Circulation moves.
Preferably, described when described heat time heating time be more than the scheduled time when, if the water temperature value at any part is detected
Still less than corresponding set temperature value, then described air conditioner heat pump hot water is controlled to open water pump, so that quiet in described water system
Also include after the step of water circulation flowing only：
Obtain the run time of described water pump；
When described run time is more than the predetermined running time, if detect water temperature value at any part still less than
Corresponding set temperature value, then control described air conditioner heat pump hot water to start shooting and run heating mode.
Preferably, described step S1 includes：
When described air conditioner heat pump hot water runs refrigeration mode, the unit water system of collection air conditioner heat pump hot water is followed in water
Water temperature value at water-side heat in endless tube road.
Preferably, the antifreeze control method of described air conditioner heat pump hot water also includes：
When described air conditioner heat pump hot water is in standby mode, obtain current outdoor ambient temperature；
When described current outdoor ambient temperature is less than predetermined outdoor environment temperature, execution step S1.
For achieving the above object, the present invention also provides a kind of air conditioner heat pump hot water, and described air conditioner heat pump hot water includes
Outdoor unit and water circulation system, described water circulation system assists at least provided with one at each part in water circulation pipe
Heater.
Preferably, the water-side heat that described water circulation system includes being connected with described outdoor unit is changed with described water side
Hot device successively and forms the terminal unit of loop, water flow switch, back water pump, and described terminal unit is connected to described water-side heat
Influent side, and described back water pump is connected to the water outlet side of described water-side heat.
Preferably, described water circulation system is also included positioned between described water-side heat influent side and described terminal unit
Water compensating valve, and one end connect described water-side heat influent side, the other end connect described water outlet side pressure difference switch.
Preferably, described water-side heat influent side and water outlet side, pressure difference switch, back water pump, water flow switch and moisturizing
It is correspondingly provided with temperature sensor at valve.
Preferably, described assisted heating device is electrical heating wire or electrically heated rod.
Air conditioner heat pump hot water and its antifreeze control method that the present invention provides, by gathering the machine of air conditioner heat pump hot water
Water temperature value at group water system part to be detected in water circulation pipe, when detecting the water temperature value at any one part to be detected
Less than corresponding set temperature value, then start the assisted heating device at corresponding component, to improve temperature and the water of this part
The water temperature of system.So, the present invention can solve air conditioner heat pump hot water because the water temperature in water system too low, and the water system leading to
The problem freezing and freezing in each part of uniting, such that it is able to improve the stability of air conditioner heat pump hot water.

Specific embodiment
It should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The present invention provides a kind of air conditioner heat pump hot water and its antifreeze control method, when air conditioner heat pump hot water is detected
Unit water system in water circulation pipe, when water temperature value at any part to be detected is less than corresponding set temperature value, then
Start the assisted heating device at corresponding component, to improve the temperature of this part and the water temperature of water system.Therefore, the present invention can
