The integrated refrigeration and heating machine can realize continuous temperature control from -150℃ to +350℃, and there is no need to replace the temperature medium when switching between heating and cooling, and it can directly perform refrigeration from high temperature, which significantly improves the efficiency of the experiment. The circulation pump is matched with other experimental instruments, which can not only provide high-temperature experiments for instruments that need high-temperature heating, but also provide low-temperature liquid for instruments that need to be cooled, realizing multiple purposes of one equipment. So how should customers choose a cooling and heating all-in-one machine that suits their needs?

When purchasing a cooling and heating integrated machine, a variety of factors should be considered, such as heating power, circulation pressure, cooling capacity, flow rate, etc., and various working conditions require different models of the corresponding cooling and heating cycle integrated machine. If the model of the cooling and heating cycle machine is not selected properly, it will slightly affect the running time of the equipment and increase the cost of use. In severe cases, the equipment cannot be operated and used normally, making the equipment useless to purchase. So the first thing we have to do is to figure out how much low temperature we are using and the required capacity. These two values ​​are also important factors affecting the price of the cooling and heating all-in-one machine, so as to avoid the occurrence that the purchased equipment cannot reach the operating temperature, or the power supply is excessive. resulting in a waste of resources. The second is the power of the device. Many users only consider the heat dissipation and cooling of the power supply when purchasing the power supply, but do not care about the power of the water pump. If the power of the pump is lower than the flow rate, it cannot meet the requirements of use. If the power of the water pump is too large, we don’t need that much power at all, which will cause energy loss and increase the cost of use.

When choosing a high and low temperature all-in-one machine, the following factors should be considered:

1. Determine the basic requirements of the reactor during the temperature control process of the reactor

Users have different requirements for temperature control of reactors, material, quantity, inlet temperature, inlet temperature, and precision requirements. Therefore, the corresponding models and sizes also have certain differences. Users need accurate process data, and choose suitable ones based on these data. model.

2. Determine the model of the high and low temperature all-in-one machine

The heat transfer oil of the high and low temperature all-in-one machine is generally a special heat transfer oil, and the type of reaction medium can be determined according to the temperature requirements of the reaction kettle. According to their own site conditions, make supporting preparations. For some special environments, the isolated explosion-proof type can also be customized according to the corresponding requirements, and there are corresponding explosion-proof grades.

3. Determine the parameter configuration of the high and low temperature all-in-one machine

After the user provides the manufacturer with accurate operating data, the manufacturer will provide the corresponding cooling and heating temperature control scheme after calculation. In the scheme, the model and parameter configuration will be selected. The user can see the brand of each accessory in the parameter configuration. After the calculation, the corresponding cooling and heating control scheme will be provided. Some accessories have a variety of brands to choose from. If users have requirements, they can contact to modify. Generally, it is a standard configuration, but it can also be customized. There are many factors to be considered in the selection of the integrated cooling and heating cycle machine. The location and environment of the integrated cooling and heating cycle machine should also consider the size and size, and reserve a corresponding ventilation position for placing the equipment.
