The invention discloses a refrigerating and heating carpet, which is applied to household rooms and various halls. The refrigerating and heating carpet consists of fuzzy
fiber, a
copper pipe, an expansion valve, a compressor and an external unit, wherein the entire carpet is braided to a required size by using organic fuzzy fibers; a layer of
copper pipe loop is inserted into the middle of the carpet, and is distributed by folding in a reciprocating way in the carpet plane as shown in the attached drawing of the specifications; the two ports of the
copper pipe are connected with the expansion valve and the compressor outside the carpet; the expansion valve and the compressor are connected with the external unit; the external unit is arranged outside a room, and is a
heat exchanger with a fan; during working, the power supply of the carpet is switched on, so that the copper pipe, the expansion valve, the compressor and the external unit constitute a
heat pump working unit; during heating, the compressor is used for driving working mediums (R134a and the like) to circulate physically in a
system, be evaporated for absorbing heat in the external unit and be liquefied for releasing heat in the copper pipe of the carpet; the refrigerating process is reverse to the heating process; and the carpet distribution area is relatively wide and is equivalent to the floor area of the room, so that the
room temperature convection effect is not remarkable, and the refrigerating or
heating effect is extremely mild. Compared with an ordinary carpet, the refrigerating and heating carpet has the advantages of comfortable and attractive effects, refrigerating or heating function, mild acting effect and high comfort.
