Description

Technical Field

[0001] The utility model relates to the technical field of heating systems, in particular to a heat pump system for constant ambient temperature of water in aquaculture. Background Art

[0002] Conventional aquaculture generally maintains the aquaculture temperature by preheating and precooling the water for water exchange in advance. After heating or cooling the water exchange reservoir to a predetermined temperature, the treated water is injected into the aquaculture pool through a circulating pump to achieve the purpose of regulating the pool water temperature and balancing the pool water environment. Conventional systems only deal with the temperature of the water, and a separate heating and cooling system is required for the indoor temperature of the workshop. At the same time, conventional systems generally do not perform constant temperature treatment on the aquaculture pool. In order to maintain a constant water temperature in the aquaculture pool, new water can only be injected into the aquaculture pool. Although this can keep the water temperature constant, the newly injected water will affect the number and density of fungi in the original water body. It is difficult to control the effect of constant temperature and stable flora in the pool by injecting new water alone. This causes changes in the growth environment of aquatic products and may cause unstable quality of aquatic products. If the water quality is to be kept stable, the amount of new water injected needs to be controlled, and the water temperature may not be kept constant. If the amount of water is changed too much, some new water will be wasted in order to achieve stable water quality and temperature, which means that some heat will be wasted due to excessive injection of new water. If the water temperature is to be kept stable, the amount of water injected needs to reach a certain amount, and the water environment may change, which is not conducive to the growth of aquatic products. It is difficult to meet the requirements of both conditions. Conventional aquaculture systems have poor water temperature regulation capabilities and a relatively simple system that cannot meet the needs of aquatic products at different stages.

[0080] The utility model system performs multi-directional control on the production environment of aquaculture projects, and is mainly divided into three main directions for independent control.

[0081] Direction 1: Environmental temperature control. Use air coolers to control the indoor environment, which can better maintain the heat dissipation from the breeding pool to the surrounding environment, thus reducing the rate of change of water temperature in the breeding pool and making the temperature of the breeding pool more stable.

[0082] Direction 2, to control the water temperature of the breeding pool, coils are arranged in the breeding pool, and the required cold and heat are transported to the breeding pool through pipes using a refrigerant. Because each set of coils is set for a separate breeding pool, the input of cold and heat loads can be controlled by adjusting the flow rate, so as to achieve the purpose of different water temperatures in different breeding pools. Because the existence of the coils can isolate the refrigerant and the pool water, this part is a closed system, and the refrigerant can use soft water. This part of the system consumes less water, and the probability of scaling during the heat pump heating process is also small. The circulation system is closed and clean, and the possibility of system blockage is extremely low; the second advantage of Direction 2 is that the water in the breeding pool does not need to be replaced, which can better maintain the number of ecological bacteria in the breeding pool, and is more conducive to the growth of aquatic products;

[0083] Direction three, control the water change of the breeding pond. You can set up a variety of water change pools with different water temperatures according to demand. Water change pools with different water temperatures can be conducive to water change in breeding ponds with different temperatures. In this way, the number of bacteria in the breeding pond can be adjusted by water change, and the water can also be changed at the same water temperature. Because there are multiple water change pools, one of the water change pools can be used to store high-temperature hot water, and the difference between peak and valley electricity prices can be used to store valley electricity. Then, during peak electricity, the high-temperature hot water in the high-temperature water pool can be used to adjust the water temperature of other water pools.

[0084] The water temperature constant heat pump system for aquaculture can also be used in off-season greenhouse projects, eliminating the heat exchange unit 04, constant temperature water storage unit 06, and water exchange unit 07, and pre-burying the constant temperature system of the pool water constant temperature unit 03 in the soil in the greenhouse. The system controls the ambient temperature and soil temperature of the entire off-season greenhouse, forcing plants to grow, bloom, and bear fruit in off-season under dual control.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
