Description

Technical Field

[0001] This utility model belongs to the technical field of swimming pool heat pumps, specifically, it relates to an integrated heat pump for multi-mode space dehumidification and pool water heating. Background Technology

[0002] Indoor heated swimming pools are swimming pools that maintain the water temperature at 26-28℃ throughout the year through professional equipment and technology. Their core purpose is to maintain a constant water temperature to meet the comfort needs of the human body. Indoor heated swimming pools require specific equipment to maintain a constant temperature. Currently, the equipment used in indoor heated swimming pools includes a three-in-one dehumidifying heat pump, an air-source heat pump specifically for swimming pools, an air-source water heater, and an air-source water heater shower unit. This results in an indoor heated swimming pool needing four independent systems, leading to numerous devices, a large installation area, high initial investment costs, and high maintenance costs. When the pool-specific dehumidifying pump dehumidifies the hot and humid air, a portion of the high-humidity air from the pool interior is discharged through the exhaust duct at the return air vent. The remaining high-humidity air mixes with fresh air and is then sent to the internal evaporator via an air filter. Moisture is separated during the air condensation process. After treatment, the air is reheated. Existing exhaust ducts cannot effectively control the amount of high-humidity air discharged. When the outdoor temperature is low, the less high-temperature, high-humidity air is discharged, the greater the energy consumption of the evaporator's dehumidification and cooling process. Conversely, when the outdoor temperature is high, the more high-humidity air is discharged, the greater the energy consumption of the evaporator's dehumidification and cooling process. This results in energy waste and increased operating costs.

[0003] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] like Figures 1 to 4 As shown, this is a multi-integrated dual-mode space dehumidification pool water heating integrated heat pump, consisting of a heat pump unit 1 and a return air duct 2. One end of the return air duct 2 extends into the constant temperature pool hall 5, with the return air inlet 4 located near the top of the hall. The other end of the return air duct 2 is connected to the air inlet of the heat pump unit 1. A temperature and humidity sensor 15 is installed on the return air duct 2 at the air inlet of the heat pump unit 1. An air inlet fan 17 is installed at one end of the heat pump unit 1 near the return air duct 2. An exhaust duct 8 is installed above the air inlet fan 17. A fresh air duct 9 is installed on the side of the exhaust duct 8. An electric air valve 14 is installed at the exhaust duct 8. The heat pump unit 1 on the side of the exhaust duct 8 is equipped with... The control box 16 contains a tubular heat exchanger 18 located in the heat pump unit 1, corresponding to the fresh air duct 9. Below the tubular heat exchanger 18 is a dehumidifying compressor 19. On the side of the dehumidifying compressor 19 is an evaporator assembly 20. On the other side of the evaporator assembly 20 is a tubular heat exchanger 24. Below the tubular heat exchanger 24 is a reheating compressor 25. On the side of the reheating compressor 25 is an air outlet fan 26. The air outlet fan 26 is connected to the air supply duct 6. The other end of the air supply duct 6 extends into the constant temperature swimming pool hall 5. The air supply duct 6 has multiple air outlets for supplying treated circulating air into the constant temperature swimming pool hall 5.

[0025] The constant temperature swimming pool hall 5 is equipped with an indoor constant temperature pool 12. An overflow trough 13 is provided on the outer edge of the indoor constant temperature pool 12. A temperature and humidity sensor 15 is installed on the outside of the fresh air duct 9 to monitor the external ambient temperature.

[0026] The indoor constant temperature pool 12 is connected to tubular heat exchanger 18 and tubular heat exchanger 24 through an inlet pipe. The liquid outlet of tubular heat exchanger 18 and tubular heat exchanger 24 is connected to circulating pump unit 11 through an outlet pipe. Both tubular heat exchanger 18 and tubular heat exchanger 24 are titanium alloy heat exchangers.

[0027] The return air duct 2 enters the heat pump unit 1 section and is equipped with a return air static pressure box 3. The supply air duct 6 exits the heat pump unit 1 section and is equipped with a supply air static pressure box 7. The return air static pressure box 3 has the functions of stabilizing pressure and reducing noise, balancing supply and return air pressure, and promoting the circulation and utilization of fresh air.

[0028] Both the dehumidifier compressor 19 and the reheat compressor 25 are equipped with multiple sets of outdoor condensers 10. Both the dehumidifier compressor 19 and the reheat compressor 25 are connected to the outdoor condensers 10 through copper pipes. The outdoor condensers 10 are located outside the heat pump unit 1 housing.

[0029] Both the return air duct 2 and the supply air duct 6 are equipped with 70℃ fire dampers. The liquid inlet connection pipe of the circulating pump unit 11 is equipped with a pressure gauge, an electric valve, and a check valve. The liquid outlet connection pipe is equipped with a Y-type filter, a shut-off valve, a thermometer, and a pressure gauge to achieve effective temperature control and circulation.

[0030] The evaporator assembly 20 includes a finned evaporator 21, a reheat condenser 22, and a water coil surface cooler 23. An intermediate mixing valve 27 is provided at the mixing point of the humid hot air and the external fresh air of the heat pump unit 1 to mix the gases.

[0031] The working principle of this utility model is as follows: the inlet fan 17 draws warm and humid air from the pool room through the return air duct 2, and supplies it into the heat pump unit 1 through the return air static pressure box 3. The temperature and humidity sensor 15 of the return air duct 2 detects the humidity of the gas. If the return air humidity is 80% and the temperature difference between the indoor and outdoor environments is within 5℃, the exhaust volume of the electric damper 14 is adjusted to 70% to increase the exhaust volume, expel more humid and hot air, replenish the dry outdoor air, and reduce the energy consumption of the dehumidification process. If the outdoor and indoor air temperatures and humidity are relatively similar... When the exhaust volume of the electric damper 14 is adjusted to 50%, it is in normal exhaust mode. When the outdoor temperature is ≥10℃ lower than the indoor temperature, the exhaust volume of the electric damper 14 is adjusted according to the temperature difference to increase the exhaust volume, expel the warm, humid air and introduce the cool, dry air. After the air is mixed, it is dehumidified, which can effectively reduce energy consumption. When the outdoor temperature is ≥7℃ higher than the indoor temperature, the exhaust volume of the electric damper 14 is adjusted according to the temperature difference to decrease the exhaust volume, reduce the entry of the hot outside air, and reduce the energy consumption for cooling and dehumidification after air mixing.

[0032] The dehumidification process is as follows: Air flows through the evaporator (dehumidifier) ​​coil, and while cooling and dehumidifying, the heat energy generated by the evaporation of pool water is transferred to the cold liquid refrigerant. This energy exchange causes the air temperature to drop below the dew point, forming condensation on the evaporator coil. The formed water flows into the equipment's liquid collection tray and is discharged through the drain pipe. The humid air is transformed into dry, cold air. After the liquid refrigerant flows through the evaporator, the recovered air heat energy becomes a low-temperature, low-pressure gaseous refrigerant. The low-temperature gaseous refrigerant then enters the compressor, where it is transformed into a high-temperature gaseous state. The high-temperature gaseous refrigerant flows through the main unit's air-cooled condenser, the pool water heating condenser, or the outdoor evaporator condenser. At this point, the high-temperature gaseous refrigerant changes from a gaseous state to a liquid state, releasing the recovered heat to heat the indoor air or pool water. When it is necessary to heat the indoor air, the main unit's air-cooled condenser operates, sending out dry, hot air to raise the temperature of the indoor air. If the indoor air temperature reaches the required level, the recovered condensation heat is used to heat the pool water, and the main unit sends out dry cold air to cool the indoor air. If both the indoor air temperature and the pool water temperature reach the required level at the same time, the recovered condensation heat is discharged into the outdoor atmosphere through the outdoor evaporator condenser. The high-temperature gaseous refrigerant condenses into a warm liquid after flowing through the condenser, releasing condensation heat. When the indoor air temperature exceeds the required upper limit, the main unit's air-cooled condenser stops working, and cold air is sent out through the dehumidifying evaporator to cool and lower the indoor air temperature.

[0033] The evaporator, compressor, condenser, circulating pump, tubular heat exchanger, temperature and humidity sensor 15, etc. used in the device are all existing technologies. The related components that are matched with the above equipment will not be described in detail. The swimming pool constant temperature and humidity control system is equipped with a PLC programmable controller and its supporting components (not shown in the attached figure), a touch screen display, and Chinese language display. The system can be expanded with Fiel bus, Lon Works, Modbus RS485, FTP, HTTP and other communication protocols for remote control. All of them adopt existing control technologies. The evaporator is equipped with an air filter, which is not shown in the attached figure.

[0034] Initial heating of pool water: After the pool is filled with water for the first time, the pool water needs to be initially heated. At this time, the pool water temperature is low and there is no moisture evaporation. The system runs in pool water heating mode. The heating components are external (not shown in the attached diagram). The outdoor unit absorbs heat from the air and releases it into the pool water through the indoor titanium tube condenser. The indoor fan does not start.

[0035] Constant temperature dehumidification: While the system cools and dehumidifies, the evaporator recovers heat from the pool and releases it into the water through a titanium tube heat exchanger. The heat recovery rate reaches over 95%. When the heat is insufficient, the outdoor unit starts and absorbs heat from the air to supplement the pool. In winter, the system operates in dehumidification and heating mode. The system's heat is used to maintain the constant temperature of the pool water and the air. When the air temperature is too low, the system operates in strong heating mode to quickly heat the air.

[0036] This utility model's heat pump unit 1 can extract high-humidity air from the constant-temperature swimming pool hall 5, dehumidify, dry, and heat it up, and then return it to the indoor swimming pool hall. Before dehumidification and drying, a portion of the high-humidity air is discharged and fresh air is supplied to facilitate indoor-outdoor gas exchange, thereby effectively ensuring the air quality circulating into the swimming pool hall. An electric air valve 14 is installed at the exhaust duct 8 of the heat pump unit 1, and a temperature and humidity sensor 15 is installed on the return air duct 2 connected to the heat pump unit 1 to monitor relevant parameters of the return air. A temperature and humidity sensor 15 is installed on the outside of the fresh air duct 9 to monitor the external ambient temperature. After comparing and analyzing the monitoring data, the control box 16 controls the exhaust volume of the exhaust duct 8, thereby effectively reducing the temperature and humidity of the mixed gas and reducing the energy consumption of the subsequent dehumidification and cooling equipment.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
