What are the main components of an air source heat pump?
3. Compressor: it can raise the low-pressure gas to a kind of driven fluid machinery, which is the heart of the air heat pump;4 expansion valve: expansion valve is an important part of the air source heat pump, generally installed in the storage tank and evaporator. The liquid refrigerant expansion valve temperature and pressure through the throttle to steam at low temperature and low pressure, then the refrigerant in the evaporator to absorb heat to the cooling effect, the valve valve to control the flow through the evaporator superheat change at the end of the expansion, to prevent the emergence of the evaporator area use and knock phenomenon.
Extension of knowledge point:Air source heat pump is a device that uses air as a high grade (low grade) heat source for heating (cooling). Air as a low-grade heat source, can be inexhaustible, inexhaustible, everywhere, free access. Air source heat pump installation flexible, easy to use, relatively low initial investment, and more suitable for household installation. The working principle is as follows:
The air heat pump consists of the following parts:1: evaporator: evaporator is an important part of air source heat pump, low temperature condensation "liquid" through the evaporator, and the outside heat exchange of the air, "gas" heat absorption, to achieve the effect of refrigeration;2 condenser: it can transfer the heat in the tube to the air near the pipe in a very fast way;
