Problems solved by technology

[0004] It is well known that electric heating devices have a coefficient of performance equal to 1, while thermal loops operating in heat pump mode have a coefficient of performance that is generally greater than 1, but decreases significantly as the temperature of the external environment into which the heat is delivered decreases

Embodiment Construction

[0039] figure 1 A first air conditioning system is shown diagrammatically in which the method according to the invention can be carried out.

[0040] The air conditioning system comprises a thermal loop 1 comprising at least one external heat exchanger 10 , internal heat exchanger 11 , compressor 12 , expansion device 9 and evaporator 13 . The thermal loop is of the air-air type. By "air-to-air" we mean that the heat generated by the thermal loop 1 is transferred directly to the air flow through the air conditioning system. The heat loop operates according to a so-called "heat pump" mode. By "heat pump" we mean that the heat loop generates calories in order to heat the air flow through the air conditioning system. The internal heat exchanger 11 operates as a condenser in this heat pump mode.

[0041] The air conditioning system also includes a supplemental electric heating device 2 that heats the air flow through the air conditioning system. The air conditioning system fu...

Abstract

The method involves determining air flow on an internal heat exchanger (11) or a water-air exchanging radiator. A total heating capacity is calculated from temperature set point, temperature of the air flow and the air flow on the exchanger. A heating capacity of an air-air type thermal loop (1) is determined. The heating capacity of the thermal loop is compared with the total heating capacity. A heating capacity of a complementary electric heating device (2) is adjusted by balancing the heating capacity of the loop if the heating capacity of the loop is less than the total heating capacity. Independent claims are also included for the following: (1) a computer program comprising a set of instructions to implement an air-conditioning system controlling method (2) a computer readable recording medium comprising a computer program having a set of instructions to implement the air-conditioning system controlling method.

Description

technical field [0001] The present invention relates to the general field of control methods for motor vehicle air conditioning systems. More specifically, the invention relates to a control method for an air-conditioning system comprising a thermal loop operating according to a so-called "heat pump" mode, the thermal loop comprising at least one external heat exchanger, an internal heat exchanger or a water-air exchange radiator, compressor and evaporator, wherein the thermal loop provides the heating capacity of the thermal loop, and supplementally, the air conditioning system includes electrical heating means The unit provides supplemental heating capacity for the electrical unit. The air conditioning system according to the invention also comprises a control device in which the method according to the invention is carried out. Background technique [0002] In such air conditioning systems, which are commonly used in hybrid or electric vehicles, the full heating capacit...
