Description

Technical Field

[0001] The invention relates to the technical field of air-conditioning heat pump heating and hot water systems. Background Art

[0002] Indoor air conditioning, hot water and heating are common needs of people, and sustainable development requires energy conservation and low carbon environmental protection. However, the current household air conditioners produce cold air indoors in the summer and emit a large amount of heat energy to the outdoors, which cannot be used to make hot water, which is a waste of energy. In addition, traditional air conditioners are idle for a long time in areas with indoor central heating in spring, autumn and winter, and the equipment utilization rate is too low, which is also a waste. Research and development of energy-saving products that can be used for both cooling and hot water in the summer and using air conditioners as heat pump water heaters in the spring and autumn is the dream of people in the refrigeration and heat pump industry. The applicant has applied for and authorized Several related patents have been obtained, such as "A dual-effect four-season energy-saving cooling and heating air-conditioning and hot water three-in-one machine", patent number: 00264455.x; "A four-season energy-saving cooling and heating air-conditioning and hot water three-in-one machine", patent number: 02116049.X; Currently, a small number of 5-horsepower central air-conditioning trigeneration air-conditioning and hot water machines are produced on the market, which still use two four-way valves (one is actually a three-way valve). However, due to the complex structure, many welding points and high failure rate, they have not been widely promoted; the dual-generation system promoted in recent years is popular with "sky fluorine and ground water" and has no special innovation; although it is comfortable, the work is not very convenient. The cost of floor heating exceeds that of air conditioning heat pumps. Due to the large heat capacity of floor heating and slow startup, continuous heating is required. For office workers, the heat from continuous heating is dissipated to the environment through the walls of the house, and the energy-saving effect is greatly reduced. In order to overcome the above-mentioned shortcomings of existing air conditioners and heat pump water heaters, the applicant has accumulated more than 20 years of experience and has applied for several related patents, among which the following have been published: "Summer cooling and winter heating four-season water heater", patent application numbers: 202410732219.4, 202421290011.3, which can achieve summer cooling in principle. It can produce both hot water and heating water in winter. In spring and autumn, an independent air-source heat pump circulates to produce hot water. In summer, hot water is completely free. In spring and autumn, hot water saves more than 72% energy than electric water heaters, and in winter, it saves 50% energy. However, the technology needs to be improved and the technical solutions need to be innovated. "Integrated cold, hot and hot water multifunctional machine", patent application numbers: 202410953422.4, 202421682569.6, uses cold water for cooling and hot water for heating, extends the cooling and heating space, and adds dehumidification and heating and humidification and heating functions in winter, but its triple water supply circuit is too complicated, which affects its promotion.

In addition, the advanced version of the new three-purpose cooling and heating air-conditioning water heater also adds a hot water circulation with dehumidification and heating and hot air humidification and heating functions, which makes up for the shortcomings of lowering the room temperature due to dehumidification and excessive dryness of the indoor humidity during the winter heating period in the north.

[0017] The novel three-purpose cooling and heating air-conditioning water heater is characterized in that the four circulating fluorine paths for the three functions of heating, cooling and hot water are respectively placed in the two working positions of the four-way valve: heating position and cooling position; the four circulating fluorine paths of the four novel three-purpose machines are constructed and operated as follows:

[0018] (1) The first new type of three-in-one machine is a parallel type three-in-one machine

[0019] The two circulating fluorine paths of the four-way valve in the heating position are: 1) The first hot water circulating fluorine path (outdoor heat absorption and hot water production): compressor (operation), hot water heat exchanger (heat absorption), first throttle, outdoor heat exchanger (heat absorption), four-way valve (heating position ②④ paths), liquid receiver, compressor; 2) Heating circulating fluorine path: compressor (operation), four-way valve (heating position ①③ paths), indoor heat exchanger (fan turns on, heat is released, fluorine circulates; fan stops, no heat exchange, fluorine gas does not circulate), third throttle (for liquid circulation, for gas resistance The fluorine circuit operates as follows: the first hot water circulation fluorine circuit is the path for the condensed fluorine liquid produced when the hot water heat exchanger is heating water.

When the water temperature reaches the set value, the outdoor fan is automatically turned on, the heat transfer temperature difference of the hot water heat exchanger is reduced, and the amount of fluorine condensation is reduced and the flow is automatically reduced to zero; the refrigeration circulation fluorine circuit, because the outdoor fan is turned on, the condensed fluorine liquid generated when the indoor heat exchanger is heating is throttled into the indoor heat exchanger and the refrigeration circulation passage;

[0021] (2) The second new type of three-in-one machine is a front-mounted three-in-one machine

[0022] The two circulating fluorine paths of the four-way valve in the heating position are: 1) The first hot water circulating fluorine path (outdoor heat absorption and hot water production): compressor (operating), hot water heat exchanger (hot water production), gas-liquid separation cylinder (gas-liquid separation, fluorine liquid flows out of the liquid outlet), first throttle, outdoor heat exchanger (heat absorption), four-way valve (heating position ②④ paths), liquid receiver, compressor; 2) Heating circulating fluorine path: compressor (operating), hot water heat exchanger (water temperature is low to produce hot water, water temperature reaches the set value, fluorine gas passes through), gas-liquid separation cylinder (gas-liquid separation, fluorine gas flows out of the gas outlet), four-way valve (heating position ①③ paths), indoor heat exchanger (fan running, heating, fluorine circulation); Fan stops, no heat is released, and fluorine does not circulate), the third throttle (for liquid circulation, blocking gas), outdoor heat exchanger (fan turns on, absorbing heat), four-way valve (②④ passages), liquid receiver, compressor; the fluorine circuit operation status is as follows: the first hot water circulation fluorine circuit is the passage for condensed fluorine liquid generated when the hot water heat exchanger produces hot water. When the water temperature reaches the set value, the indoor fan or circulating water pump is automatically turned on, the heat transfer temperature difference of the hot water heat exchanger is reduced, and the amount of fluorine condensation is automatically reduced. Because the throttle is blocked, the retained gas in the fluorine circuit is forced to divert to the heating circulation fluorine circuit; in the heating circulation fluorine circuit, the indoor fan or circulating water pump is running, generating condensate to release heat, thus heating the cycle;

[0023] The two circulating fluorine paths of the four-way valve in the cooling position are: 3) The second hot water circulation fluorine path (indoor heat absorption hot water circulation fluorine path): compressor (running), hot water heat exchanger (heating water), gas-liquid separation cylinder (gas-liquid separation, fluorine liquid flows out from the liquid outlet), second throttle, indoor heat exchanger (heat absorption cooling), four-way valve (cooling position ③④ path), liquid receiver, compressor; 4) Refrigeration circulation fluorine path: compressor (running), hot water heat exchanger (water temperature is low to make hot water, water temperature reaches the set value, fluorine gas passes through), gas-liquid separation cylinder (gas-liquid separation, fluorine gas goes to the outlet), four-way valve (cooling position ①② path), outdoor heat exchanger (fan turns to release heat , fluorine circulation; fan stops, no heat dissipation, fluorine does not circulate), the fourth throttle (for liquid circulation, blocking gas), one-way valve, indoor heat exchanger (heat absorption and cooling), four-way valve (③④ passages), liquid receiver, compressor; the operation of the fluorine circuit is: the second hot water circulation fluorine circuit, which is the fluorine liquid flow path when making hot water (and cooling), when the water temperature reaches the set value, the outdoor fan is started to run, the heat transfer temperature difference of the hot water heat exchanger is reduced, and the amount of fluorine condensation is automatically reduced. Because the throttle is blocked, the retained gas in the fluorine circuit is forced to divert to the heating circulation fluorine circuit; in the cooling circulation fluorine circuit, because the outdoor fan is running, the outdoor heat exchanger produces condensate, which is throttled into the indoor heat exchanger, and the refrigeration cycle;

[0024] (3) The third new type of three-purpose machine is a rear-mounted three-purpose machine

[0025] The four-way valve is in the heating position and has two circulating fluorine paths: 1) the first hot water circulation fluorine path (outdoor heat absorption hot water circulation fluorine path) and 2) the heating circulation fluorine path are the same: compressor (running), four-way valve (heating position ①③ paths), indoor heat exchanger (fan stopped, fluorine gas passes; fan running, indoor heating), second one-way valve, hot water heat exchanger (indoor fan stopped, full amount of heat collected to make hot water; fan running, subcooled liquid sensible heat and waste heat to make hot water), first throttle, outdoor heat exchanger (heat absorption), four-way valve (heating position ②④ paths), liquid reservoir, compressor; the fluorine path operation is: this fluorine path is a fluorine path shared by heating and hot water, because the indoor fan is stopped, the fluorine gas condenses in the hot water heat exchanger, releasing heat to make domestic hot water; because the indoor fan is running, the indoor heat exchanger condenses, releasing heat to heat the room, and the condensed fluorine liquid is throttled by the first throttle and enters the outdoor heat exchanger to absorb heat, performing a heating and hot water circulation;

[0026] The four-way valve is in the two circulating fluorine paths of the cooling position: 3) The second hot water circulating fluorine path (outdoor heat absorption hot water circulating fluorine path) is the same as the fluorine path of 4) the cooling circulating fluorine path; compressor (running), four-way valve (cooling position ①② path), outdoor heat exchanger (fan stops, no heat exchange, fluorine gas passes; fan starts, heat is released, fluorine gas condenses), first one-way valve, hot water heat exchanger (when the outdoor fan stops, full heat is collected to make hot water; when the outdoor fan starts, the fluorine subcooled liquid uses sensible heat and waste heat to heat water), second throttle, indoor Internal heat exchanger (absorbing heat from refrigerated air or chilled water), four-way valve (paths ③ and ④), liquid receiver, compressor; The fluorine circuit operates as follows: This fluorine circuit is shared by both cooling and hot water production. Because the outdoor fan is stopped, fluorine gas condenses in the hot water heat exchanger, releasing heat to produce domestic hot water. Because the outdoor fan is running, the outdoor heat exchanger releases heat, and the condensate passes through the hot water heat exchanger, releasing sensible heat from the subcooled liquid and continuing to heat the water. Finally, the fluorine liquid passes through the second throttle and enters the indoor heat exchanger for cooling, completing the cooling and hot water cycle.

[0027] (4) The fourth type of three-in-one machine is a semi-parallel and semi-rear-mounted three-in-one machine.

[0028] The two circulating fluorine paths of the four-way valve in the heating position (semi-parallel type) are: 1) The first hot water circulating fluorine path (outdoor heat absorption hot water circulating fluorine path): compressor (running), four-way valve (heating position ①③ path), second one-way valve, hot water heat exchanger (hot water), first throttle, outdoor heat exchanger (fan turns to absorb heat), four-way valve (heating position ②④ path), liquid receiver, compressor; 2) The fluorine path of the heating circulating fluorine path is: compressor (running), four-way valve (heating position ①③ path), indoor heat exchanger (fan stops, no heat exchange, fluorine gas is retained and cannot pass; fan turns, heat is released to the room, function Heating, condensate flow), third throttle (liquid passage, gas blocking), outdoor heat exchanger (fan switches to heat absorption), four-way valve (heating position ②④ passage), liquid receiver, compressor; the fluorine circuit operation is as follows: the first hot water circulation fluorine circuit is the passage for condensed fluorine liquid generated when the hot water heat exchanger is heating water. When the water temperature reaches the set value, the indoor fan or circulating water pump is automatically turned on, the heat transfer temperature difference of the hot water heat exchanger is reduced, and the amount of fluorine condensation is reduced, and the flow is automatically reduced to no flow; the heating circulation fluorine circuit is the passage for condensed fluorine liquid generated when the indoor heat exchanger is heating due to the indoor fan or circulating water pump being turned on, heating cycle;

[0029] The four-way valve is in the two-circulation fluorine circuit of the cooling position (semi-post-position): 3) The second hot water circulation fluorine circuit (outdoor heat absorption hot water circulation fluorine circuit) is the same as the 4) refrigeration circulation fluorine circuit; compressor (running), four-way valve (cooling position ①② path), outdoor heat exchanger (fan stopped, no heat exchange, fluorine gas passes; fan running, heat released, fluorine gas condenses into liquid and passes), first one-way valve, hot water heat exchanger, second throttle, indoor heat exchanger (absorbs heat from cooling air or chilled water), four-way valve (③④ path), liquid receiver, compressor; when the outdoor fan stops, full heat is collected to produce hot water; the fluorine circuit operation is: this fluorine circuit is a fluorine circuit shared by cooling and hot water. Because the outdoor fan stops, the fluorine gas condenses in the hot water heat exchanger to produce domestic hot water; because the outdoor fan is running, the outdoor heat exchanger releases heat, the condensate passes through the hot water heat exchanger, and then releases the sensible heat of the subcooled liquid to continue heating water. Finally, the fluorine liquid passes through the second throttle and enters the indoor heat exchanger, completing the refrigeration cycle.

[0030] The novel three-in-one cooling and heating air-conditioning water heater and the signal detection control system detect signals including: the hot water temperature Tw of the hot water tank, the indoor temperature Ta, and the indoor humidity φ. The control system implements the principle of hot water priority and, based on user needs, controls the heat exchange in the cooling and heating fluorine circuits and the circulation of fluorine gas simply by switching a four-way valve and starting and stopping the outdoor fan, indoor fan, and the circulating water pump associated with the fluorine water-indoor heat exchanger, thereby achieving control over the four circulation functions and operations of the novel three-in-one water heater. The specific control procedure is as follows:

[0031] When the four-way valve is in the heating position, there are two refrigerant circuits: 1) the first hot water circulation refrigerant circuit and 2) the heating circulation refrigerant circuit. The operation of these two refrigerant circuits is controlled by starting and stopping the indoor fan and the circulating water pump related to the indoor heat exchanger. When the indoor fan and the circulating water pump stop, the indoor heat exchanger in the heating circulation refrigerant circuit does not exchange heat, and all the refrigerant gas enters the first hot water circulation refrigerant circuit, where the refrigerant condenses and releases heat to produce hot water in the hot water heat exchanger. When the indoor fan and the circulating water pump are running, the outdoor heat exchanger absorbs heat and the indoor heat exchanger provides heating.

[0032] When the four-way valve is in the cooling position, there are two configured refrigerant circuits: 3) the second hot water circulation refrigerant circuit and 4) the cooling circulation refrigerant circuit. The operation of these two refrigerant circuits is controlled by starting and stopping the fan of the outdoor heat exchanger. When the outdoor fan stops, the outdoor heat exchanger in the cooling circulation refrigerant circuit does not exchange heat, and all the refrigerant gas flows into the second hot water circulation refrigerant circuit, where the refrigerant condenses and releases heat to produce hot water in the hot water heat exchanger. The condensed liquid enters the indoor heat exchanger through the second throttle valve for refrigeration. When the outdoor fan is running, the outdoor heat exchanger releases heat and the indoor heat exchanger provides refrigeration.

[0033] The operation and stop of the indoor fan and the circulating water pump, as well as the rotation and stop of the outdoor fan, are determined by comparing the hot water temperature Tw of the hot water tank and the indoor temperature Ta with the set values. Let Tw0 be the upper limit value of the set hot water temperature, which can be adjusted between 40 - 55°C, and △Tw be the allowable water temperature fluctuation value for the set temperature drop. Usually, it is defaulted that Tw0 = 50°C and △Tw = 5°C.

[0034] When Tw ≤ (Tw0 - △Tw) (the lower limit value of the set water temperature), and Ta < T0h (the set heating room temperature), the four-way valve is in the heating position, and the indoor fan and the circulating water pump stop to produce hot water with concentrated full heat.

[0035] When Tw ≤ (Tw0 - △Tw) (the lower limit value of the set water temperature), and Ta > T0c (the set air-conditioning cooling room temperature), the four-way valve is in the cooling position, the outdoor fan stops, and concentrated full heat is used to produce hot water; it also produces air-conditioning cold water.

[0036] When Tw ≥ Tw0 (the upper limit value of the set water temperature), and Ta < T0h (the set heating room temperature), the indoor fan and the circulating water pump run; concentrated heat is used for heating.

[0037] When Tw ≥ Tw0 (the upper limit value of the set water temperature), and Ta > T0c (the set air-conditioning cooling room temperature), the outdoor fan runs to provide centralized cooling for the indoor area.

[0038] The described new type of three-in-one air-conditioning and hot water machine is characterized by having three basic modes: hot water production, cooling with hot water production, and heating with hot water production modes; two additional modes (available in the advanced version): dehumidification with heat compensation and hot air humidification modes. The specific control programs for the five operation modes, the starting and stopping of the corresponding electrical components, the operating refrigerant circuits, and the combined heat and power supply system are as follows:

[0039] (1) The hot water making mode is an independent hot water making mode in spring and autumn. The four-way valve is in the heating position (①③, ②④ are connected, and the coil is energized). The following is executed: the first hot water circulation fluorine circuit, the compressor and the outdoor fan are running; after the user manually presses the button or specifies the "hot water making" mode by voice control, it enters automatic control: 1) The indoor fan and the circulating water pump stop, the heating circulation fluorine circuit does not exchange heat, and the fluorine gas does not circulate; 2) The hot water circulation pump runs, the hot water circulation heating water circuit runs, and the corresponding integrated water tank hot water heat exchanger is used for self-circulation heating; 3) The hot water outlet system discharges hot water under pressure;

[0040] When Tw≤(Tw0-△Tw)(1), the hot water mode is automatically started;

[0041] When Tw≥Tw0(2), the hot water mode is automatically stopped, the compressor, indoor and outdoor fans stop running; the four-way valve is still in the heating position (the coil potential remains unchanged); to exit the hot water mode, manual intervention is used, that is, the "off" button is pressed;

[0042] (2) Cooling and hot water mode is a cooling and hot water mode in summer. The four-way valve is in the cooling position (①②, ③④ are connected, and the coil is not powered). The three-way valve is in the first and third interface connection position (hot water circulation heating path). Ta is the room temperature control parameter. The user can adjust the cooling room temperature Ta0c. The default Ta0c = 26℃. After the user manually presses the button or specifies the "cooling and hot water" mode by voice control,

[0043] When Ta>Ta0c(3), the cooling and hot water mode is automatically started, and the second hot water circulation fluorine circuit of the two fluorine circuits is in operation; the hot water priority principle is implemented, and the operation of the cooling circulation fluorine circuit is controlled by the water temperature Tw of the hot water tank:

[0044] When Tw≤(Tw0-△Tw), the outdoor fan stops, the outdoor heat exchanger does not exchange heat, and fluorine gas is retained in the refrigeration cycle fluorine circuit; the second hot water circulation fluorine circuit operates, and the hot water heat exchanger fully collects heat to produce hot water; the indoor heat exchanger absorbs heat for cooling, and the indoor fan of the fluorine-air-indoor heat exchanger starts to blow cold air; the circulating water pump starts, the fluorine-water-indoor heat exchanger produces chilled water, and the fan of the water-air-fan coil heat exchanger starts to blow cold air;

[0045] When Tw≥Tw0, or the outdoor fan delay reaches the set time (to simplify control, the outdoor fan delay start control can also be used, usually 10-20 minutes), the outdoor fan starts to operate, the refrigeration cycle fluorine circulates, the outdoor heat exchanger dissipates heat, and the indoor heat exchanger cools; the water temperature in the hot water tank will rise by more than 50℃ due to absorbing the heat of the superheated high-pressure refrigerant. Let it rise naturally without intervention;

[0046] When Ta=Ta0(4), the compressor and indoor fan are kept running at low speed; the circulating water pump and hot water circulating pump are stopped;

[0047] When Ta < (Ta0 - △Tac) (5) and Tw ≥ Tw0, the compressor, indoor and outdoor fans, circulating water pump, and hot water circulating pump stop running; the four-way valve remains in the cooling position; Note: △Tac is the allowable temperature fluctuation of the room temperature in the cooling mode, and it is recommended to default △Tac = 1°C;

[0048] (3) The heating and hot water mode is the mode of heating in winter and making domestic hot water. The four-way valve is in the heating position (①③ and ②④ are internally connected, and the coil is powered on), and the three-way valve is in the position where the first and third interfaces are internally connected (the position of circulating domestic hot water); the user can adjust and set the heating room temperature Ta0h, with the default Ta0h = 22°C; when the user presses the manual button or voices to specify the "heating and hot water" mode,

[0049] When Ta < Ta0h (6), the heating and hot water mode starts to run, and the first hot water circulation fluorine circuit runs automatically; the principle of giving priority to making hot water is implemented.

[0050] When Tw ≤ (Tw0 - △Tw), the indoor fan and the circulating water pump do not operate, the fluorine gas in the heating circulation fluorine circuit does not condense, and the fluorine gas flows concentratedly through the first hot water circulation fluorine circuit, and all the heat is collected in the hot water heat exchanger to make domestic hot water.

[0051] When Tw ≥ Tw0, the indoor fan and the circulating water pump operate, the fluorine gas in the heating circulation fluorine circuit flows, and the indoor heat exchanger makes hot air and heating hot water; the water temperature in the hot water tank will exceed 50°C due to absorbing the heat of the superheated refrigerant gas, and there is no need to intervene naturally.

[0052] When Ta = Ta0h, the compressor and the indoor fan operate at low speed.

[0053] When Ta > (Ta0h + △Ta0h) and when Tw ≥ Tw0, the compressor, indoor and outdoor fans stop running; the four-way valve remains in the heating position; △Ta0h is the temperature allowing the room temperature to be too high, and the default △Ta0h = 1°C.

[0054] (4) Dehumidification and heating mode: This mode is only available for high-end models equipped with dehumidification and heating devices and for users in the south of the Yangtze River. It is a dehumidification and heating mode when the room temperature is low and the humidity is high. Start-up conditions: When the indoor relative humidity Φ≥65% and the room temperature is lower than 22°C, the dehumidification mode is started by human intervention or automatic means. Control: The four-way valve is in the cooling position (①②, ③④ are connected, and the coil is without electricity), and the three-way valve is in the second and third interface connection position (humidification and heating circulation water circuit operation position); the compressor, outdoor air The machine is running; the refrigeration cycle fluorine circuit is running, the indoor fan is running at a low wind speed, and dehumidification is carried out; water circuit operation: 1) The cooling / hot water circulation circuit, the fan of the water-air heat exchanger is running at a low speed; the circulating water pump is running, and the water-air fan coil heat exchanger blows cold air to dehumidify; 2) The humidity control and heat supply circulation circuit is running, the three-way valve (②③ passages) and the hot water circulation pump are running, and the hot water generated by the hot water heat exchanger is used to supply heat to the dehumidification and heat supply unit (hot air humidifier); when the indoor relative humidity Φ is less than 50%, dehumidification is stopped by manual intervention or automatic means;

[0055] (5) Hot air humidification mode: This mode is only applicable to the advanced models equipped with hot air humidifiers and users in the areas north of the Yellow River. It is enabled during the winter heating period when the indoor humidity is Φ<40% and the room temperature is ≥22℃. The system fluorine circuit still operates in the heating mode, and the four-way valve is in the heating position (①②, ③④ are connected, and the coil has no electricity). However, the three-way valve is in the connection position between the second and third interfaces (②③ paths), the humidity control and heating circulation water circuit is running, and the humidification and water supply valve is opened. When Tw≤(Tw0-△Tw), the three-way valve returns to the connection position between the first and third interfaces (②③ paths), the hot water circulation heating water circuit is running, and the humidification and water supply valve is automatically closed. Or when Φ>50%, the humidification and water supply valve is automatically closed. If Tw>Tw0, the three-way valve is in the connection position between the second and third interfaces (②③ paths), and the hot air humidifier is used as a water-air-fan coil heat exchanger to participate in heating the room.

[0056] The novel three-purpose cooling and heating air-conditioning water heater is provided with an automatic defrost cycle in the heating and hot water mode; the starting conditions of the defrost cycle are: when the outdoor temperature is lower than 5°C during the heating mode operation, the temperature difference between the outdoor air temperature and the tube wall temperature of the outdoor heat exchanger suddenly exceeds the set value, or the tube wall temperature of the outdoor heat exchanger suddenly drops rapidly, and the drop rate exceeds 1 times the normal drop rate, the control system issues a defrost command and enters the defrost mode operation; its characteristics are: the four-way valve is controlled to be in the cooling position, the fluorine path is the same as the refrigeration cycle fluorine path, the outdoor fan stops, and the indoor fan stops; when the model is equipped with a fluorine water-indoor heat exchanger, the cold / hot water circulation water path is in operation, the circulating water pump is in operation, and the hot water in the water supply tank is used to heat the fluorine water-indoor heat exchanger of the indoor heat exchanger, which can quickly defrost.

[0057] The novel three-purpose cooling and heating air-conditioning and water-heating machine is characterized in that: the novel three-purpose cooling and heating air-conditioning and water-heating machine adopts the cold / hot water circulation zone coordinated cooling / heating mode, and arranges water-air-fan coil heat exchangers in the living room, study, master bedroom, second bedroom, etc.; the water-air-fan coil heat exchanger is a wall-mounted thin rectangular box with a forced convection heat exchanger with a wind wheel, the wind wheel can be stepped speed-regulated or DC speed-variable, the inlet and outlet are equipped with temperature detection, which can be directly displayed, or transmitted to the host control panel by wire or wirelessly, and the wind wheel speed can be adjusted manually or remotely; the zone coordinated control mode is to adjust the indoor fan and the zoned water-air-fan coil exchanger in accordance with the data detected by the room temperature and humidity sensors arranged in each area, the duration and demand of the human activity area. The fan speed of the water-to-air fan coil heat exchanger is used to regulate the time and intensity of cooling / heating in each area, and the cooling or heating amount is allocated by adjusting the fan speed of each water-to-air fan coil heat exchanger; the advanced version of the zone coordination control method is to gradually compile the cooling / heating needs of each area through theoretical modeling and artificial intelligence, and customize the intensity of cooling and heating, fan speed, and running time for automatic control; the zone coordination control method is people-oriented and serves people. It distributes cooling or heat according to the different weights of the needs of each area, and allocates limited cooling and heat to where they are most needed. It is the core foundation of intelligent control, which not only improves comfort but also saves energy, and uses cooling / heating prepared by smaller-power refrigeration equipment to meet the cooling and heating needs of larger rooms.

[0058] The novel three-purpose cooling and heating air-conditioning water heater is characterized in that: the hot air humidifier is composed of a wet mesh cloth, a water supply pipe, a hot water discharge pipe for heating the wet cloth, and a water storage tank added to the air duct of the water-air-fan coil heat exchanger; the principle of the hot air humidifier is to use the added hot water discharge pipe to heat the wet cloth when the water-air-fan coil heat exchanger is used for heating, and to use the hot air to blow through the wet mesh or wet cloth to bring water vapor into the room; the water supply pipe, the hot water discharge pipe for heating the wet cloth, and the inlet and outlet pipes of the hot water-air heat exchanger discharge pipe bundle are connected in parallel; a water supply fine-tuning valve is installed on the water inlet pipe of the water supply pipe to supply water. There are many tiny water seepage holes on the tube, and the seeping water drips into the humidifying cloth or humidifying net; the hot air humidifier is equipped with inlet and outlet air temperature detectors at the air inlet and outlet, and a humidity detector is installed at the air inlet; a touch screen control display is installed at one end of the top surface of the thin rectangular box of the hot air humidifier, which normally displays the temperature and humidity of the incoming air, the operating mode, and the fan speed gear; the overflow pipe of the water storage tank is connected to the drain pipe behind the bottom drain valve, and the drain pipe is connected to the outdoors; the water level gauge of the water storage tank is visible; the hot air humidifier is only used to provide indoor heating in winter, and the water replenishment fine-tuning valve is closed at other times.

[0059] The innovative features of the present invention are as follows:

[0060] One of the innovative highlights of the novel three-purpose heating and cooling air conditioner water heater described in this invention is the structural innovation of the hot water heat exchanger and its fluorine circuit connection. By adding a hot water heat exchanger to the traditional heating and cooling air conditioner fluorine circuit system, the fluorine circuit air inlet is designed with four connection methods, ensuring that it is always in the condenser position within the fluorine circuit, with the same pressure as the compressor exhaust, thus creating four new types of three-purpose machines. The core feature is that the liquid outlet of the hot water heat exchanger is connected to the second interface (liquid outlet) of the outdoor and indoor heat exchangers through two first and second throttles, respectively. This innovative structure uses only a four-way valve to establish four fluorine circuit cycles for three functions, distributed between the heating and cooling positions of the four-way valve.

[0061] The core of the present invention is the two-throttle connection method for the bottom liquid outlet of the hot water heat exchanger. This method breaks through the double four-way valve structure of the "cooling, heating, air conditioning and hot water three-in-one machine". Only one four-way valve can cleverly form four fluorine circuit cycles with three functions. Hot water can be produced regardless of whether the three-in-one machine is running the cooling / heating cycle. The principle of the invention is that the condensate of the hot water heat exchanger passes through the two-way throttle and automatically selects the throttling path by virtue of the pressure difference between the compressor exhaust pressure and the indoor or outdoor heat exchanger used as the evaporator. Therefore, the control is greatly simplified and the operation stability is greatly improved. The present invention does not require fluorine circuit valve control, and the refrigerant can automatically condense in the hot water heat exchanger to produce hot water, or condense in the indoor Or the outdoor heat exchanger does not exchange heat and condenses; the deep-seated principle is: when the fan of the heat exchanger connected to the hot water heat exchanger does not rotate, there is no heat exchange, and the gas pressures of the two are equal, and the fluorine gas in the cooled heat exchanger condenses into liquid, the volume is reduced hundreds of times, and the pressure is greatly reduced, so the refrigerant will continuously flow through the hot water heat exchanger with a cooling source; in the heat exchanger where the fan stops and there is no cold water heat exchange, the fluorine gas pressure cannot be reduced, and the fluorine gas cannot flow into the throttle; the throttle is a passage for liquid and a blocker for gas; the above three innovations have made the three-purpose machine with four cycles of cooling, heating and dual-source hot water production extremely simple, with obvious novelty and outstanding advancement, and are original inventions.

[0062] 2. The second innovative highlight of the novel three-in-one cooling and heating air-conditioning water heater described in the present invention is the gas-liquid separation cylinder, a key component of the second novel three-in-one machine, i.e., the front-mounted three-in-one machine. It is composed of a Y-shaped three-way joint and three sections of pipelines, and is installed vertically with the liquid outlet at the bottom, and the two interfaces of the liquid / gas inlet and the gas outlet are distributed on the two upper pipes of the Y-shaped three-way joint. Practice has proved that the Y-shaped three-way joint is used to make a gas-liquid separator, which is easy to make, has a good gas-liquid separation effect, low resistance, and can be mass-produced.

[0063] 3. The third innovative highlight of the novel three-purpose cooling and heating air-conditioning water heater described in the present invention is the third novel three-purpose machine, i.e., the rear-mounted three-purpose machine. A one-way valve is added to the second interface of the outdoor heat exchanger and the indoor heat exchanger, and the outlets of the two one-way valves are connected to the air inlet of the hot water heat exchanger. This ensures that only the refrigerant in the high-pressure circuit can enter the hot water heat exchanger, whether it is a cooling or heating cycle, and the hot water heat exchanger always acts as a subcooling heat exchanger after the indoor or outdoor heat exchanger of the condenser, absorbing the supercooling sensible heat of the refrigerant liquid, thereby increasing the cooling efficiency during cooling. The two one-way valves added to the fluorine circuit are the key technology and invention point of the rear-mounted three-purpose machine, which saves the two-way throttle between the indoor and outdoor heat exchangers and reduces the cost.

[0064] 4. The fourth innovative highlight of the novel three-purpose cooling and heating air-conditioning water heater described in the present invention is the fourth novel three-purpose machine, i.e., a semi-parallel and semi-rear-mounted three-purpose machine, in which the second one-way valve is directly connected to the inlet of the hot water heat exchanger from the third interface of the four-way valve, and together with the indoor heat exchanger connected to the third interface of the four-way valve, forms a parallel form of two heat exchangers; the hot water heat exchanger and the indoor heat exchanger each have a throttle (first and third throttles) connected to the second interface of the outdoor heat exchanger; in this way, the hot water heat exchanger is used as a subcooling heat exchanger in the refrigeration cycle to improve the refrigeration efficiency; in the heating cycle, heat can be more concentrated on the indoor heat exchanger for heating.

[0065] 5. The fifth innovative highlight of the novel three-purpose heating and cooling air-conditioning water heater described in the present invention is the innovation of fluorine circuit circulation control. The novel three-purpose heating and cooling air-conditioning water heater described in the present invention controls four circulating fluorine circuits by repositioning a four-way valve and starting and stopping the fans and circulating water pumps associated with the indoor and outdoor heat exchangers. Its control method subverts the traditional thinking of adding a control valve to the fluorine circuit to forcibly change the control mode of the fluorine circuit flow. It solves the problems of air and liquid leakage at the high and low pressure ends of the valve and the problem of poor valve switching when adding a control valve to the fluorine circuit. It is an original breakthrough innovation in the control method of the three-purpose heating, cooling, and cooling water heater. Advantages: It simplifies the structure of the fluorine circuit system and ensures stable and reliable system operation. The clever thing is: the first and second hot water circulating fluorine circuits of the fluorine circuit do not need to be controlled by valves, and the refrigerant will find the path to run automatically. In addition, a hierarchical control principle and method with hot water priority is proposed to control the start and stop of the fan and circulating water pump.

[0066] 6. The novel three-purpose cooling and heating air-conditioning water heater described in the present invention has the sixth innovative highlight, which is the design of the fluorine-air-fluorine-water-indoor heat exchanger connected in series with the indoor heat exchanger of the triple system; the key point of the series connection of the outdoor unit fluorine-air-indoor heat exchanger and the fluorine-water-indoor heat exchanger is that due to the different volumes of the two heat exchangers, the connection sequence is incorrect, and fluorine deficiency will occur during operation; the present invention correctly selects which one is installed in the indoor fluorine-air-indoor heat exchanger port to connect the four-way valve, and the installation is consistent with the indoor fluorine-air-indoor heat exchanger. The outdoor fluorine-water-indoor heat exchanger is connected to the throttle end; the reason is: when operating in heating mode, the fluorine-air-indoor heat exchanger is at the front end of the airflow, and the condensate after condensation passes through the fluorine-water-indoor heat exchanger with a small volume, so there will be no fluorine deficiency, and it also serves as a subcooler; when cooling, the fluorine-water-indoor heat exchanger first receives the throttled liquid refrigerant, evaporates, and the fluorine moisture passes through the fluorine-air-indoor heat exchanger, so there will be no fluorine deficiency, and it also serves as a superheater, which increases the enthalpy value of the fluorine gas entering the compressor and saves compression work.

[0067] 7. The seventh innovative highlight of the novel three-purpose cooling and heating air-conditioning water heater described in the present invention lies in the design of the hot water heat exchanger and the domestic hot water heating system: (1) When an integrated water tank hot water heat exchanger is used, the innovative point is that a stop valve with a fluorine line inlet and outlet interface is installed on the hot water tank shell, and one of the stop valves has a fluorine filling interface, which is convenient for the separate installation of the hot water tank for fluorine injection; (2) When the hot water heat exchanger is a high-efficiency tank or a plate heat exchanger, it is directly installed in the outdoor unit body, and the fluorine line is connected by welding to form an integrated three-purpose machine; if it is equipped with a pressurized hot water tank, the top pressure hot water outlet method is adopted; (3) If a non-pressurized hot water tank is selected, a domestic hot water heat exchange coil is placed in the hot water tank, and the domestic hot water heat exchange coil bears the tap water pressure. In high-rise buildings with high water supply pressure, it is very beneficial to avoid pressurized water tank accidents.

[0068] 8. The eighth innovative highlight of the new three-purpose cooling and heating air-conditioning water heater described in the present invention is the addition of a gas-liquid separation water supply tank to the cold / hot circulating water heat exchange circuit of the trigeneration system. The bottom water outlet is connected to the inlet of the circulating water pump, and there is an air release valve on the top of the water supply tank. This point is extremely important and is the key to ensuring that the circulating water pump can deliver water normally without bubbles.

[0069] 9. The new three-purpose cooling and heating air-conditioning water heater described in the present invention has a ninth innovative highlight. In the trigeneration system of the advanced version, a humidity regulating and heating circulation water circuit consisting of a hot water heat exchanger, a dehumidifying and heating device (which is also a hot air humidifier), and a hot water circulation pump is added. When the temperature is low in spring and the cooling and dehumidification cycle is in progress, the dehumidifying and heating device is used to heat the room; when the room is too dry during heating in winter, the hot air humidifier is used to humidify the room; the hot air humidifier is connected to the humidity regulating and heating circulation water circuit, and acts as a radiator when the water supply pipe valve is not open. When the temperature is low and the dehumidification is in progress, heat can be supplied to the room to offset the heat loss in the room during dehumidification; in winter, when the indoor humidity is too low during the winter heating period in dry northern regions, the room can be humidified, thus serving three purposes in one device.

[0070] 10. The novel three-purpose cooling and heating air-conditioning water heater of the present invention has the tenth innovative highlight. The present invention proposes an innovative hardware configuration and control concept for air-conditioning heat exchangers that rationally distribute cooling / heating in rooms for energy-saving use. It adopts a fluorine-air-fluorine-water indoor heat exchanger in which a fluorine-air-indoor heat exchanger and a fluorine-water-indoor heat exchanger are connected in series. In combination with the water-air-fan coil heat exchanger installed in each room, it forms a cold / hot water circulation water exchange circuit, which is distributed to the living room and each room as needed. This makes up for the shortcoming that fluorine-air cooling / heating cannot extend the space, extends the use space of cold / heating, shifts the peak supply, and is comfortable and energy-saving. It is the prototype of the AI intelligent control mode. In addition, the control adopts the principle of hot water production priority, and realizes the internal circulation switching of cooling / heating and hot water production in the cooling and hot water production modes and the heating and hot water production modes.

[0071] 11. The novel three-purpose cooling and heating air-conditioning water heater described in the present invention has an eleventh innovative highlight: there is a heat source for defrosting. In a system equipped with a fluorine-water-indoor heat exchanger, it completely solves the defrosting problem of the cooling and heating air-conditioning unit.

[0072] 12. The most outstanding advantage of the novel three-purpose cooling and heating air-conditioning water heater described in the present invention is that it has obvious energy-saving effect. In summer, it performs cooling and hot water production at the same time. The obtained hot water is completely free and can improve the cooling efficiency. The energy efficiency ratio in summer exceeds 8; in spring and autumn, the water-heating mode of absorbing heat from the outdoor heat can save 70-75% of electricity compared with electric water heaters; multi-mode energy-saving operation, in winter the defrosting mode has good effect and energy saving; the annual average COP of the unit for hot water production is greater than 5.5, and the system structure is simple, the control is convenient, and the unstable factors in operation are greatly resolved; in summary, the novel three-purpose cooling and heating air-conditioning water heater described in the present invention has a clear structural novelty, is original and groundbreaking, has a solid theoretical basis for innovation, has many technical innovations, has significant energy-saving effect, is outstanding in advancement, and is obviously practical, and meets the three requirements of invention patents.

Structural features: The connection method of its fluorine circuit is the same as that of Example 1 Figure 1 The difference is that the indoor heat exchanger is a fluorine-water-indoor heat exchanger 7; Example 5 performs summer cooling and hot water mode, and the fluorine circuit and control are basically the same as Example 1; the control of the four circulation operations of the three functions is achieved by switching the position of a four-way valve and starting and stopping the circulating water pump associated with the outdoor fan and the fluorine-water-indoor heat exchanger;

[0102] The cooling and heating of Example 5 is provided by a cold / hot circulating water heat exchange circuit consisting of a fluorine-water-indoor heat exchanger 7, a water-air-fan coil heat exchanger 11, 12 (wall-mounted fan coil heat exchanger) placed in each room, a circulating water pump 10, and a gas-liquid separation water supply tank 18, which exchanges heat with the indoor air of each room; the water supply tank 18 also serves as a gas-liquid separator and is provided with a bleed valve 17, the outlet of which is connected to the water inlet of the circulating water pump.

[0103] Example 6: Figure 6 This is the sixth embodiment of the novel three-in-one cooling and heating air-conditioning water heater of the present invention. The basic structure of the first novel three-in-one machine and the illustration of the circulating fluorine circuit and water circuit for the summer cooling and hot water mode are shown. Configuration: integrated water tank hot water heat exchanger; fluorine air-indoor heat exchanger; fluorine water-indoor heat exchanger + circulating water pump + water supply tank + water-air-fan coil heat exchanger; fluorine circuit connection method is the same as that of embodiments 1 and 5. Figure 1 、 5 The figures are basically the same; the difference is that the indoor heat exchanger of Example 6 is composed of a fluorine-air-indoor heat exchanger 4 and a fluorine-water-indoor heat exchanger 7 connected in series; the water inlet and outlet interfaces of the fluorine-water-indoor heat exchanger 7 are connected to the water supply pipe L4 and the return pipe L3 of the cold / hot water circulation water circuit, and together with the multiple water-air-fan coil heat exchangers 13 and 14 installed in the indoor partitions, the water supply tank 18, and the circulating water pump 10, form a cold / hot water circulation water circuit, which undertakes the task of providing cold and hot water in the partitions; the fan of the water-air-fan coil heat exchanger can be stepped speed regulation or DC variable speed, and the temperature detection is configured at the inlet and outlet, which can be directly displayed or transmitted to the host control panel by wire or wirelessly. The fan speed can be adjusted manually or remotely;

[0104] In Example 6, with the help of a cold / hot water circulation water circuit composed of a fluorine-air-indoor heat exchanger and a fluorine-water-indoor heat exchanger and multiple water-air-fan coil heat exchangers, a zoned coordinated control method can be implemented, that is, according to the data detected by the room temperature and humidity sensors arranged in each area, the duration and needs of the human activity area, the fan speeds of the indoor fan and the zoned water-air-fan coil heat exchanger are adjusted in association, and the time and intensity of the use of cold / heat in each area are regulated. The cooling or heating amount is adjusted by adjusting the fan speeds of each water-air-fan coil heat exchanger. In Example 6, the fluorine circuit is a three-body combination: an outdoor unit, an indoor unit and an integrated water tank hot water heat exchanger.

[0105] Example 7, by Figure 7 、 8 , 9 respectively; This is the advanced version of the first new three-in-one machine, configuration: the hot water heat exchanger is a plate heat exchanger, a high-efficiency tank heat exchanger, or a shell and tube heat exchanger; the water system is equipped with a hot water tank, a two-inlet and one-outlet three-way valve, and a circulating water pump; the indoor heat exchanger is a series fluorine air-fluorine water-indoor heat exchanger, with a fluorine air-indoor heat exchanger and a fluorine water-indoor heat exchanger connected in series. The heat exchange system is equipped with a circulating water pump, a water supply tank, and a water-air-fan coil heat exchanger. Figure 7 To perform the summer cooling and hot water mode; its fluorine circuit structure is the same as that of embodiment 1 and 6, see Figure 1 、 6 ;

[0106] The advanced version of the new three-purpose cooling and heating air-conditioning and water-heating machine of Example 7 is different from Examples 1 and 6 in that it has a system for providing cooling and heating in two ways: fluorine air and fluorine water, and is also equipped with a dehumidifying and heating device (also a hot air humidifier) 15;

[0107] The hot air humidifier is a water-to-air fan coil heat exchanger with a wet mesh added. When the water-to-air fan coil heat exchanger is used for heating, hot air blows through the wet mesh or wet cloth, bringing water vapor into the room. The water supply pipe, the hot water heating wet cloth pipe, and the inlet and outlet pipes of the hot water-to-air heat exchanger pipe bundle are connected in parallel. A water supply fine-tuning valve is installed on the water inlet pipe of the water supply pipe, and many fine water seepage holes are punched in the water supply pipe, so that the seeped water drips into the humidifying cloth or humidifying mesh. The hot air humidifier is equipped with inlet and outlet air temperature detectors at the inlet and outlet, and a humidity detector at the air inlet. The hot air humidifier is only used to provide indoor heating in winter. At other times, the water supply fine-tuning valve is closed, and water drips through the wet mesh automatically and quantitatively, relying on the hot water heat exchange pipe for heating and humidification of the outlet air. When the humidifier is not dripping water, it is a water-to-air fan coil heat exchanger.

[0108] Example 7 is an advanced version of the new three-purpose cooling and heating air-conditioning water heater, adding two functions: dehumidification and heating, and drying and humidification. These two functions are performed by the hot water heat exchanger 6, the dehumidification and heating device (hot air humidifier) 15, the three-way valve 12 (②③ passages), and the circulating water pump, forming a humidity and heating circulation circuit.

[0109] Dehumidification and heating mode, see Example 7 Figure 8 , the advanced version of the model has an additional mode, starting conditions: when the indoor relative humidity Φ ≥ 65% and the room temperature is lower than 22℃, the dehumidification mode is started by manual intervention or automatic mode; control: the four-way valve is in the cooling position (①②, ③④ are connected, and the coil has no electricity), and the three-way valve is in the second and third interface connection position (dehumidification and heat supplement cycle position); the compressor and the outdoor fan are running; the refrigeration cycle fluorine circuit is running, and the indoor fan runs at a low wind speed for dehumidification; water circuit operation: 1) The fan of the water-air heat exchanger runs at a low speed; the circulating water pump runs, and the water-air-fan coil heat exchanger blows cold air for dehumidification; 2) The humidification and heat supplement cycle water circuit runs, the three-way valve (②③ passages), the hot water circulation pump runs, and the hot water generated by the hot water heat exchanger is used to supplement heat to the supplementary heater (humidification heat exchanger); when the indoor relative humidity Φ < 50%, dehumidification is stopped by manual intervention or automatic mode;

[0110] Hot air humidification step, see Example 7 Figure 14 , is a sub-environment in the heating and hot water mode during the heating period, and is a new three-in-one air-conditioning and hot water machine used in dry areas in the north with a hot air humidification function added. When the indoor relative humidity Φ is ≤ 40% during the heating period and the room temperature is higher than 22°C, the humidification function cycle is started by manual intervention or automatic mode, the four-way valve is in the heating position, the system humidity adjustment and heat supplement circulation water circuit is running, the three-way valve (②③ passages), the hot water circulation pump is running, the hot water generated by the hot water heat exchanger is used to heat the hot air humidifier, and the water supply pipe of the hot air humidifier is opened to supply water and humidify. When the indoor relative humidity Φ is greater than 50%, the humidification function is stopped by manual intervention or automatic mode.

[0111] The two-inlet and one-outlet three-way valve 12 of Example 7 has a wonderful function, which is to separate the domestic hot water heating cycle and the humidity control hot water circuit. When the three-way valve is in the first three-interface path (①③), it is the hot water circulation heating water circuit. Figure 7 , execute the hot water heat exchanger and hot water tank hot water circulation heating task; when the three-way valve is in the second three-interface path (②③), it is the humidity adjustment and heat supplement circulation water path, see Figure 8 When the four-way valve is in the cooling position, it is the humidity control and heat supplement circulation water circuit; when the four-way valve is in the heating position, it is the humidity increase and heat supplement circulation water circuit. Figure 14 The heat for both dehumidification and humidification comes from the hot water heat exchanger. Regardless of whether the new three-purpose cooling and heating air-conditioning water heater is operating in cooling or heating mode, the new three-purpose cooling and heating air-conditioning water heater hot water heat exchanger will produce hot water.

[0112] Like Example 6, Example 7 has a fluorine-water-indoor heat exchanger 7 and multiple water-air-fan coil heat exchangers 13 and 14 installed in indoor partitions to form a cold / hot water circulation water path. Therefore, a zone-coordinated control method can be used to adjust the room temperature in different indoor areas, thereby achieving both comfortable and energy-saving effects.

[0113] Figure 8 This is Example 7, an illustration of the circulating fluorine circuit and water circuit circulation for executing the spring dehumidification and heat supplementation mode, with the four-way valve in the cooling position (①② circuits, ③④ circuits); the fluorine circuit operates: 1) the second hot water circulating fluorine circuit (outdoor heat absorption hot water circulating fluorine circuit); 2) the refrigeration circulating fluorine circuit; the water circuit executes: cold / hot water circulating water circuit, humidity control and heat supplementation circulating water circuit, and the circulating water pump and hot water circulating pump operate; the fluorine wind-indoor heat exchanger blows cold air for dehumidification, the water-air heat exchangers 13 and 14 dehumidify, and the heat supplementation device (water-air-fan coil heat exchanger 15) provides heat.

It can defrost quickly and is a breakthrough in ensuring safe and efficient operation of the air-conditioning heat pump in winter; when the wall temperature of the outdoor heat exchanger recovers to more than 8°C, the fluorine circuit and the water circuit automatically return to the heating mode; the present invention uses the heat of the water supply tank for defrosting, and the energy cost is only 1 / 3 of the electrical energy (compression work).

The two fluorine circuits of the four-way valve in the refrigeration position: 3) the second hot water circulation fluorine circuit and 4) the refrigeration circulation fluorine circuit are the same; Compressor, four-way valve cooling position ①② passages, outdoor heat exchanger, first one-way valve, hot water heat exchanger, second throttle, indoor heat exchanger, four-way valve ③④ passages, accumulator, compressor; Fluorine circuit operation: This fluorine circuit is shared by both cooling and hot water production. Because the outdoor fan is stopped, fluorine gas condenses in the hot water heat exchanger, releasing heat to produce domestic hot water. Because the outdoor fan is running, the outdoor heat exchanger releases heat, and the condensate passes through the hot water heat exchanger, releasing sensible heat from the subcooled liquid and continuing to heat the water. Ultimately, the fluorine liquid passes through the second throttle and enters the indoor heat exchanger for cooling, completing the cooling and hot water cycle.
