Multi-temperature multi-control constant-temperature culturing temperature controlling method and one-machine multi-temperature multi-control seafood constant temperature machine

Abstract

The invention discloses a multi-temperature multi-control constant-temperature culturing temperature controlling method and a one-machine multi-temperature multi-control seafood constant temperature machine. The multi-temperature multi-control constant-temperature culturing temperature controlling method comprises the steps that a plurality of culturing containers are used for culturing seafood, an independent constant-temperature control process is used in each culturing container, and the constant-temperature control process comprises the step that a steam compressing type cooling system is used for cooling a circulating water source of the corresponding culturing container; and an electric heating device is used for heating the circulating water source of the corresponding culturing container, and the same compressor is used for compressing cooling agent gas of the steam compressing type cooling systems of all the culturing containers. According to the temperature controlling method, cooling and heating of fish tanks do not interfere with each other, the whole seafood constant temperature machine can carry out cooling and heating at the same time, and the power of the compressor can be used to a high degree.

Description

technical field [0001] The invention relates to a seafood breeding method and equipment, in particular to a temperature control method for multi-temperature and multi-control constant temperature cultivation and a multi-temperature and multi-control seafood constant temperature machine. Background technique [0002] Seafood constant temperature machine, also known as seafood machine or seafood chiller, is used in temperature control systems such as seafood farming. , thermostat, four-way valve and other components. Its working principle is that the sensor senses the water temperature signal and transmits it to the thermostat to start cooling or heating. The four-way reversing valve is used to switch the direction of the refrigerant and exchange the condenser. And the position of the evaporator, so as to achieve the purpose of cooling or heating switching. The seafood machine is widely used in the cooling and heating of seafood pools and fish tanks. It is a water temperature...

AI Technical Summary

Problems solved by technology

The problems caused by such a large number of seafood thermostats are: high requirements for installation space; multiple sets of noise are generated at the same time, and the heat generated is large, resulting in poor heat dissipation and affecting the ambient temperature; installation is cumbersome

What's more important is that the power of the compressor is not fully utilized, resulting in waste of power and high cost of use. The power of the seafood thermostat in the existing market exceeds 1p. Generally, the power of 1 horsepower thermostat can control the water volume of 1 ton, but a fish tank The total amount of water generally does not exceed 400 kg, and the power of the seafood thermostat is less than half. For example: the cooling capacity of 1 compressor is 2500 kcal / h, and the cooling capacity required to reduce 1 °C per kg of water is 1 kcal / h. Assuming that there is 400 kg of water in the fish tank, from normal temperature 25 ℃ to 16 ℃, the temperature difference is 9 degrees, the required cooling capacity is 400 kg × temperature difference 9 ℃ = 3600kcal / h, such as 4 hours to reduce the temperature of each fish tank to the required temperature , as long as the cooling capacity of each cylinder is about 900kcal / h, which is equivalent to a 0.36p compressor

[0004] The problem still exists in the existing constant temperature seafood machines is that the reversing valve is used for heating, that is, the direction of the refrigerant is switched by using a four-way reversing valve, and the positions of the condenser and the evaporator are exchanged, so as to achieve the purpose of switching between cooling and heating

In winter, when the outdoor temperature is too low, its heating effect is extremely poor. In order to keep the temperature constant, the seafood thermostat changes with the weather, cooling in hot weather and heating in cold weather. The compressor is basically in a long-term working state, which also affects the compressor. service life of
