Valve for an indoor temperature regulating system and an air temperature conditioning unit comprising such valve

A valve (1) for an indoor temperature regulating system wherein said valve (1) comprises a fixed valve housing (2) having a main body (4) provided with at least six valve connections (201-206, 205′, 206′) and a valve selector (3) being moveable relative the valve housing (2) for selectively connecting said valve connections (201-206, 205′, 206′) such that the valve (1) may be switched by moving the valve selector (3) to provide a circulating flow in a first mode (I), in which a first fluid source F1, connected to the first valve connection (201) and the second valve connection (202), is connected to a treatment unit (T) connected to the fifth valve connection (205, 205′) and the sixth valve connection (206, 206′), and a second mode (II), in which a second fluid source (F2), connected to the third valve connection (203) and the fourth valve connection (204), is connected to the treatment unit (T) connected to the fifth valve connection (205, 205′) and the sixth valve connection (206, 206′) wherein

• said valve selector (3) comprises a disc plate (67) having a lower disc plate portion (6) provided with openings (601-606, 605′, 607″, 609, 610) and said valve main body (4) is provided with valve openings (401-406, 402′, 404′, 405′, 406′, 402″, 404″) being connected via channels to said valve connections (201-206, 205′, 206′), said valve selector (3) and valve main body (4) being designed such that they may slide against each other, said valve (1) being designed such that
• in the first mode (I) the first valve opening (401), connected to the first valve connection (201), is in register with a lower disc plate opening (601, 610) and the fifth or sixth valve opening (405, 405′ or 406, 406′), being connected to the fifth valve connection (205, 205′) respectively the sixth valve connection (206, 206′), is in register with a lower disc plate opening (602, 610) such that a first flow path from the first valve opening (401) to either of the fifth or sixth valve opening (405 or 406) connecting the first fluid source F1 with the treatment unit T is enabled, and
• the second valve opening (402, 402′, 402″), connected to the second valve connection (202), is in register with a lower disc plate opening (605, 605′, 607″, 609) such that a second flow path from the second valve opening (402) to the other one of the fifth or sixth valve opening (405 or 406) connecting the first fluid source F1 with the treatment unit T is enabled, and
• in the second mode (II) the third valve opening (403), connected to the third valve connection (203), is in register with a lower disc plate opening (601, 610) and the fifth or sixth valve opening (405, 405′ or 406, 406′) is in register with a lower disc plate opening (602, 610) such that a first flow path from the third valve opening (403) to either of the fifth or sixth valve opening (405 or 406) connecting the second fluid source F2 with the treatment unit T is enabled, and
• the fourth valve opening (404, 404′, 404″), connected to the fourth valve connection (204), is in register with a lower disc plate opening (606, 605′, 607″, 609) such that a second flow path from the fourth valve opening (404, 404′, 404″) to the other one of the fifth or sixth valve opening (405, 405′ or 406, 406′) connecting the second fluid source F2 with the treatment unit T is enabled.
