At present, there are many types of heat pump water heaters on the market, mainly three series of solar boost type, water source and air source. The solar booster heat pump is a heat pump technology used in combination with heat pump and solar energy technology; the water source heat pump uses a certain temperature water source (above 20 ° C) as a heat source to use refrigerant as a medium to absorb heat from the water source and compress it through a compressor. Heating, exchange heat with cold water through a heat exchanger to achieve heating and hot water production. The water source heat pump must have a certain temperature and flow of water; the air source heat pump uses a similar method of water source heat pump to obtain heat from the air to heat the water. Among the three heat pumps, the air source heat pump is subject to the least restrictions and the development space is the largest. In this health care, the air source heat pump water heater is analyzed and discussed. The heat pump can be divided into the following types according to the source of the heat source: water source heat pump, ground source heat pump, air source heat pump, dual source heat pump (water source heat pump and air source heat pump combined) Heat pumps can be divided into low temperature heat pumps and ordinary heat pumps according to the type of working environment temperature. The heat pump can be divided into: medium temperature heat pump (50-70 degrees) high temperature heat pump (80-90 degrees) according to the type of heat generation temperature. Wireless Smart Pressure Transmitters
The Wireless Pressure Transducer is a cost effective replacement to a traditionally wired pressure transducer that offers the advantages of a low-cost installation in inaccessible and expensive installation environments. The wireless pressure sensor manufactured for simple measurements on a variety of applications.
The Smart Pressure Transmitter is easy to install and operate. Smart transmitters operate differently than analog transmitters. A smart transmitter uses a microprocessor that contains information about the sensor`s specific characteristics in response to pressure and temperature inputs.
