The introduction of outdoor fresh air in summer is favorable for reducing the relative humidity of the swimming pool, and simultaneously, the content of toxic gases such as chlorine in the air of the indoor swimming pool can be reduced.
Referring to fig. 1 and 2, after entering the second evaporator, the first indoor return air has two paths for supplying air to the indoor space, and the first path is that the first indoor return air is cooled and dehumidified by the second evaporator and then directly supplies air to the indoor space by the high-temperature dehumidifying air feeder; the second path is that the first indoor return air is cooled and dehumidified by the second evaporator and the first evaporator in sequence, and then is mixed with the outdoor fresh air cooled and dehumidified by the sensible heat exchanger to supply air to the indoor space.
The first indoor return air is cooled and dehumidified through the second evaporator and the first evaporator in two stages, and then is supplied to the indoor space, so that the refrigerating and dehumidifying effects are achieved. Because there are second evaporator and the first evaporator of different evaporating temperature, when dehumidification and refrigeration load are not high, can only open the second evaporator, second evaporator and first evaporator provide different evaporating temperature and dehumidify, compare single thermal cycle recovery system, evaporating temperature has obtained the improvement, has improved system efficiency.

When the swimming pool hot water heat exchanger is not used in summer, the outdoor condenser and the first heat exchanger can realize the condenser function in the refrigeration cycle. The cooling gas of first heat exchanger is the second indoor return air and is gaseous through the gas after sensible heat exchanger intensifies, and this gas temperature is showing and is being less than the outdoor circulated air in the outdoor condenser, and the heat transfer effect of first heat exchanger also can obviously be higher than outdoor condenser, therefore the gaseous flow of this application has improved the whole heat transfer effect of condenser.
As shown in fig. 4a, outdoor fresh air (fresh air point 1 in the psychrometric chart 4 a) passes through a sensible heat exchanger and is cooled to fresh air point 2 in fig. 4a in an equal humidity manner, and then is mixed with return air 3 (air obtained by sequentially passing first indoor return air through a second evaporator and a first evaporator) to change an air state point into mixed air 1 in fig. 4a, wherein the mixed air 1 is used as indoor supply air (mixed air 1 in the psychrometric chart 4 a) and is sent into the swimming pool.
Return air flow enthalpy diagram referring to fig. 4b, the first indoor return air (return air 1 in enthalpy diagram 4 b) is processed to return air 2 through the second evaporator, and is processed to return air 3 through the first evaporator, and the return air 3 is mixed with the fresh air after being processed by the sensible heat exchanger, and is sent to the swimming pool as indoor supply air.
Referring to the enthalpy diagram of the exhaust flow, as shown in fig. 4c, the second indoor return air (exhaust air 1 in the enthalpy diagram 4 b), the exhaust air 1 is processed to the exhaust air 2 through the sensible heat exchanger, the exhaust air 2 is processed to the exhaust air 3 through the first heat exchanger, and the exhaust air 3 is greater than or equal to the enthalpy value of outdoor air, so that the waste of the enthalpy value of the exhaust air is avoided, the heat exchange effect of the condenser is improved, and the efficiency of the system is improved. The exhaust air 1 can also be directly processed by a sensible heat exchanger to reach an enthalpy value equal to that of outdoor air and then discharged.
The application can adopt the following two methods to carry out heat and humidity control:
(1) The humidity of the first indoor return air is reduced in the process of supplying air to the indoor through the second evaporator, and the effect of heat and humidity control can be achieved by controlling the air quantity;
(2) The first indoor return air is cooled and dehumidified by the second evaporator and the first evaporator, and the heat and humidity load borne by the first evaporator is adjusted by controlling the air quantity passing through the first evaporator.
The two methods can flexibly adjust the heat and humidity load proportion born by the first evaporator and the second evaporator. When the heat and humidity load is lower, the first indoor return air can meet the heat and humidity requirement only through the second evaporator without passing through the first evaporator, and the evaporation temperature of the system is increased at the moment, so that the efficiency of the system is improved. When the heat and humidity load is large, the heat and humidity load born by the second evaporator can be increased by increasing the air supply quantity of the first indoor return air which passes through the second evaporator and then is supplied to the indoor air, so that the evaporation temperature of the system is increased, and the overall efficiency of the system is improved.
The application provides a reason that indoor swimming pool heat recovery method efficiency of dehumidification in summer promotes is as follows:
1. the heat exchange equipment comprises a first evaporator and a second evaporator, when the dehumidification and refrigeration load is not high, only the second evaporator can be started, and the overall efficiency of the refrigeration system is improved by increasing the evaporation temperature.
2. The heat exchange equipment is provided with a first evaporator and a second evaporator, the temperatures of the first evaporator and the second evaporator are different, the airflow quantity in the first evaporator and the second evaporator can be independently controlled, and the heat-humidity load ratio of the first evaporator and the second evaporator can be adjusted by adjusting the air passing quantity in the first evaporator and the second evaporator. The higher the heat-moisture load ratio in the second evaporator is, the larger the system evaporation temperature is increased, and the higher the overall efficiency is.
3. Heat exchange equipment passes through the heat pump principle, absorbs the gained heat of dehumidification in the evaporimeter, through compressor pump heat to condenser (outdoor condensation, swimming pool hot water heat exchanger, first heat exchanger are the condenser), and condenser (swimming pool hot water heat exchanger) can supply with the heat swimming pool pond water heating to realize heat recovery.
4. The swimming pool hot water heat exchanger does not always need heat exchange in summer working condition, and when the swimming pool hot water heat exchanger is not used, the outdoor condenser and the first heat exchanger can realize the condenser function in the refrigeration cycle. The cooling gas of the first heat exchanger is the gas of the second indoor return air heated by the sensible heat exchanger, the temperature of the gas is obviously lower than that of outdoor circulating air in the outdoor condenser, and the heat exchange effect of the first heat exchanger is also obviously higher than that of the outdoor condenser, so that the whole heat exchange effect of the condenser is improved by the gas flow.
All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is specific and detailed, but not to be understood as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
