The Features Of The Vertical Condenser And Shower-Type Condenser

Vertical shell and tube condenser


The main features of the vertical condenser are:
1)    Due to the high cooling flow and flow rate, the heat transfer coefficient is high, generally about K = 600 ~ 700 (kcal / m2? H? ℃).
2)    Vertical installation covers small areas, and can be installed outdoors.
3)    Cooling water flow directly and have high flow rate, so not need high water quality, the general water can be used as cooling water.
4)    Scales in pipe can be easy removed, and do not have to stop the refrigeration system work.

5)    But in the vertical condenser, the rise temperature of cooling water is generally only 2 ~ 4 ℃, logarithmic average temperature difference is generally about 5 ~ 6 ℃, so need much water. And because the equipment is placed in the air, the tube is susceptible to corrosion and is easier to find its leaking.

Shower type condenser

The main advantages of the shower-type condenser are:
1)    simple structure, easy to manufacture;
2)    easy to find ammonia leakage, and easy maintenance;
3)    easy to clean;
4)    low water quality requirements
The main drawbacks are:
1)    low heat transfer coefficient is low;
2)    high consumption is high;
3)    large covered areas.
The shower-type condenser take away the condensation heat by water temperature rising and water evaporates in the air. This condenser is mainly used in large and medium-sized ammonia refrigeration system. It can be installed in the open air, can also be installed in the cooling tower below, but should avoid direct sunlight.

Safety Considerations for Plate Heat Exchanger Design

图片
Hofmann During the process, there are some safety considerations you should notice: 1. Design specifications. The design specifications of heat exchangers include the types of working fluid and flow, import and export temperature, working pressure and heat exchanger efficiency. Aerospace heat exchangers should also include permissible pressure drop, size and quality. 2. Overall arrangement. First you should choose the type and structure of heat exchangers, the form of fluid flow and the materials, and then choose the type of heat surface, to consider the operating temperature and pressure, etc. 3. Heat design. The thermal design of the heat exchanger includes heat transfer calculation, flow calculation and determination of size. In addition to technical performance indicators, thermal design also need heat transfer characteristics (including heat transfer characteristics, flow characteristics and structural parameters) and fluid and material thermal activity p

Plate Heat Exchanger 2.1 Improve heat transfer efficiency Plate heat exchanger is a wall-type heat transfer heat exchanger, hot and cold fluid are transferred through the heat exchanger plate, fluid and plates are directly in contact with each other, and the heat transfer mode is conduction and convective heat transfer. The key to improve the heat transfer efficiency is to improve the heat transfer coefficient and logarithmic mean temperature difference 。 1). Improving the heat transfer coefficient of the heat exchanger is at the same time to improve the heat and heat on both sides of the plate surface heat transfer coefficient, reduce the thermal resistance of the dirt layer, choose high thermal conductivity of the plate, reduce the thickness of the plate in order to effectively improve the heat transfer. a. Improve the surface heat transfer coefficient of the plate Since the ripple of the plate heat exchanger can make turbulence of the fluid at a small flow rate
