What is the introduction of hot and cold dual purpose two temperature control unit?

Glad Caedley chiller for you.

The dual-temperature control mold temperature machine is a kind of conversion of electrical energy into heat energy to heat the material to be heated. In the operation, the low-temperature fluid medium enters its inlet under the pressure effect through the pipeline, takes away the high-temperature thermal energy that occurs in the operation of the electric heating element, and increases the temperature of the heated medium.

During the normal operation of the dual-temperature control mold temperature machine, it is forbidden to add new heat transfer oil to the heating system. After the system is started, if the pressure difference between the inlet and outlet of the heat transfer oil in the circulating system fluctuates greatly, the temperature difference exceeds the limit value, and the flow rate is lower than the set value, the system can not be put into normal operation. It is necessary to adhere to the guidelines for on-duty patrol inspection, and the personnel on duty should check the key parts of the system, such as circulating pumps, high-level tanks, liquid level gauges, pressure gauges, temperature control surfaces, flow meters, bypass filters, etc., and clean up abnormalities in time.

When inspecting or inspecting the heat conduction oil furnace, a 12V low-voltage explosion-proof lamp should be used. It is necessary to formulate emergency measures and plans to deal with power outages in Russia, and really protect the furnace tubes and heat transfer oil. In case of a power outage in Russia, the coal-fired heat transfer oil furnace should open the furnace door and stop heating.

Put the cold oil from the high tank into the low tank through the furnace tube, and use a hand pump to pump the oil from the low tank into the high tank for circulation, so as to reduce the temperature of the system. If a standby oil circuit or self-provided generator is set up to connect the circulating pump, the circulation of the heat transfer oil system is very good.

The outlet of the dual-temperature control mold temperature machine obtains the high-temperature medium required by the technology. The internal control system of the electric heater actively regulates the output power of the electric heater according to the temperature sensor signal of the output port, so that the medium temperature of the output port is uniform; Prevent the over-temperature of the heating material from causing coking, deterioration and carbonization, and cause the heating element to burn out when it is severe, and effectively extend the service life of the electric heater. In order to ensure the safe and normal operation of the heating equipment system of the heat conduction oil furnace, the equipment operation manager should pay attention to the key.

The working principle of the integrated cooling and heating machine is that the pump drives the heat transfer medium (usually water or oil) from the oil tank equipped with the built-in heater to the temperature control equipment, and then from the temperature control equipment back to the oil tank. The controller adjusts the temperature of the thermal fluid according to the temperature measured by the temperature sensor or the internal temperature of the temperature control equipment, so as to adjust the temperature of the temperature control equipment.

The all-in-one cooling and heating machine is divided into two parts: the heating part and the cooling part. The temperature control is accurate, and it is widely used in injection molding, chemical industry, rubber extrusion, reaction kettle, blow molding and other industries.

The integrated cooling and heating machine can realize mutual switching, speed up the production progress, reduce energy consumption, improve the molding efficiency of the product, suppress the defects of the product, and reduce the generation of defective products. Computer touch control, automatic calculation, multi-point temperature control unit can be customized. It can automatically and accurately control the temperature, and the set temperature can be quickly reached, and the set value and actual value are displayed separately.

Isolated electrical control box, extend the service life of electrical appliances, pipeline explosion-proof device, built-in safety protection, low noise, high temperature resistance, anti-corrosion and anti-rust, unique heating design, power-saving and durable, suitable for use in different temperature control places.

Generally, it is adjusted with PID.

This adjustment method is easy to achieve, the control accuracy is relatively high, and the control objective is strong. As long as the design is reasonable, the temperature control realization cycle is short.

The combined heating and cooling rubber pump unit has some advantages: 1. Energy saving, free heat supply while refrigeration; Or at the same time of heating, it provides free cooling capacity, and Liang Ye has a high energy utilization rate. 2. Environmental protection, no exhaust gas, waste liquid, waste residue discharge in the whole refrigeration or heating process, and truly zero emission.

3. Save time and labor. Fully intelligent temperature control technology, automatically adjust the energy of the unit without manual intervention.

The refrigeration and heating machine is also called the high and low temperature machine, the refrigeration and heating machine, the refrigeration and heating circulation device, with a wide working range, is a common high and low temperature control system in the pharmaceutical, chemical, biological and other industries, which can refrigerate and heat the temperature control for the reactor, tank, reactor, fermentation tank, extraction, distillation, etc., and provide heat and cold sources.

Zhengzhou Great Wall science, industry and trade cold and heating machine use characteristics.

1. Wide temperature control range: -120 +250.

2. The pre-cooling system, refrigeration system and heating system can be used together.

3. Rapid heating or cooling.

4. The cooling rate is large, and it can be forced to cool down quickly.

5. Fully closed circulation system, heat conduction fluid is not easy to volatilize and oxidize at high temperature; It is not susceptible to environmental conditions at low temperatures, which can extend the service life of the heat transfer fluid.

6. The refrigeration heat exchanger adopts a fully brazed plate heat exchanger, which occupies a small space and has high heat exchange efficiency.

7. Liquid level display function, real-time monitoring of liquid level, to avoid lack of heat-carrying fluid.

8. Over-temperature protection, leakage protection, over-current protection and other protection functions to fully ensure the safety of users and equipment.

9. According to the needs of users, two types of pre-cooling models can be provided: air-cooled and water-cooled.

The cooling and heating machine is also the meaning of the high and low temperature integrated machine, and it is also the refrigeration and heating temperature control system, which controls the high temperature and low temperature of the material.

At present, the long-term use of ** air conditioning unit, but ** air conditioning installation is generally larger than the cost-effective, if the company area is small, you still have to consider something else.

How many air conditioners to install, how much to install one, I'll come.

Bottled water is placed above the machine, which is used in conjunction with bottled water. Bottled water dispenser appeared before the middle of the 20th century, this water dispenser is designed as a special connector on the top of the fuselage to place the bucket, the most ** foreign water dispenser puts the bottled water in the lower part of the machine, sucked in by the suction pump, this way is safer and more hygienic than the conventional water dispenser, due to the different water dispensers, there are many kinds of barrel specifications. In the U.S. and China, most 5-gallon drums are used, while the standard size in other countries is liters (also known as 19 or 20 liters).
