Constant temperature with a cooling system with the development tank

Pa; P, and an indoor air vapor pressure, Pa; B,ed hardy clothing, B a standard atmospheric pressure, respectively and the local atmospheric pressure, Pa; v the latent heat of vaporization of water. 1/Kg; Q a heat transfer, w. ② glass tank for the environment around the surface of the heat A, Q and the surface radiation heat transfer of radiation heat transfer is calculated the same. B, natural convection heat transfer Q2c and natural convection heat transfer surface of the formula the same. Only because of convective flow in different forms and the selected C, n may vary. ③ glass tank at the bottom of the heat exchanger and the environment A, the surface radiation heat transfer and heat radiation for the same formula. B, natural convection heat transfer \ Only because of convective flow in different forms and the selected C,air jordan shoes cheap, n may vary. (2) the amount of cooling loss calculation of cold water tank cooling tank of cooling loss calculation and the calculation of similar glass fish tank load. In order to reduce cooling loss, and its size should be as small as possible in order to accommodate the cooling coil can prevail. However, the size of the cooling coil depends on the total cooling consumption, therefore, with the preparation of the cooling load calculation procedure to determine the size of the cooling water tank and cooling consumption. (3) oxygen pump air cooling consumption is difficult due to the cold calculation to determine, so the calculation of the total people than the total amount of the correction factor in the cold. ( 4) to determine the total load () 0Q0 =} (+ Q +%++++ Q) w Bu correction factor, take the tank} = 1.154 temperature structural design of the overall structure of 4.1 with refrigeration unit,air jordans, cooling tank, pumps, tanks, automatic integration of the structural design of oxygen equipment, not only compact and improve the reliability of the device. And the transportation is convenient. 4.2 to determine the tank size and the automatic setting of oxygen equipment and fish tank the size of the main dimensions, stocking a large number of tanks on the surface of the water, the water depth may be appropriate to larger, because the large area of water. Dissolved Oxygen strength. But the water generally should not be too deep, hollow of a tree to prevent severe hypoxia and deep dyed 5. Fish tank water depth less than 500 mm. In order to increase the oxygen content of water, return to the cold water tank in the loop before setting up a water oxygen device, so that the water each time to go through a process of enhanced oxygen. 4.3 determine the size of the cooling tank cooling tank size is determined by the total load of the device. But it affected the size of the total cooling load, the design to accommodate a standard cooling coil, through a computer program by its basic dimensions. 4.4 refrigeration equipment and the choice of control determined according to the calculation of cooling load, use the advanced compact Panasonic rotary compressor (Model 2S3). L8 cooling agent for the R22; and using air -cooled condenser, to save water, simplifying the system. Since most fish for narrow temperature animals, they can easily result in large temperature difference between infection and even death, therefore, must be precise temperature control thermostat, so the use of temperature control Technology Co., Ltd. Taiwan proudly produced fishpond special temperature control Instrument selection of 45 water filter surface exposed to the environment, but the fish continue to carry out metabolism,ugg prezzo, plus put food scraps, for the propagation of harmful bacteria to create the conditions for the survival of the fish caused a great deal of prestige Association. Therefore, set the pump at the filter pump, filter materials, use non-toxic and good glass wool filter performance, without adversely affecting its water quality. 5, the conclusion 5l tank with a constant temperature cooling system is designed to fish safety through the summer, and in other seasons, but also increase the heater thermostat to keep the fish tank water temperature. Optimum temperature is 52 normal physiological activity of fish Sheng important conditions, however, fish health , but also on many other conditions. For example, the oxygen in the water environment, bacteria, insects and other standard tank can not fully meet these conditions, therefore, that the fish tank and could only prolong life, to make the fish do not get sick. Must also take some other measures, such as frequently changes the water. 53 selected water source, if the choice of tap water. Should allow the standing water in containers more than three days, the chlorine completely escape the water (also called \ caution. References 1.
