摘要:
An air-conditioning system is designed at least for an air-conditioning mode for cooling a thermal control medium (13) and a heat-pump mode for heating the thermal control medium. The system comprises a refrigerant circuit with a compressor (1) and an evaporator (8), a coolant circuit with a heat-generating unit (10) to be cooled and a heater (12) for heating the thermal control medium, and also a first refrigerant/coolant heat exchanger (3) functioning on the refrigerant side as a condenser/gas cooler. The evaporator is formed by a second refrigerant/coolant heat exchanger (8). A cooling body (14) for cooling the thermal control medium is connected downstream of heat exchanger (8) on the coolant side.
摘要:
An air conditioning system has a refrigerant cycle, a coolant cycle, a refrigerant/coolant heat exchanger, coupling these cycles so as to transfer heat, and valve for operating mode-dependent control of the refrigerant flow, whereby the air conditioning system can be operated not only in air conditioning mode but at least also in a heat pump or reheat mode. An internal combustion engine exhaust gas/coolant heat exchanger is connected upstream in series to the refrigerant/coolant heat exchanger in the coolant cycle at least in the heat pump mode; and/or in the reheat operating mode the refrigerant/coolant heat exchanger functions as a condenser/gas cooler, connected upstream in series on the coolant side to the supply air/coolant heat exchanger. In addition or as an alternative, a drying operating mode can be provided for drying the supply air/refrigerant heat exchanger with reversed air conveying direction.

The invention relates to an air-conditioner having a heat exchanger, such as an evaporator, for example, with a reservoir for a cold storage medium.

In a condenser for an air-conditioning system, in particular for an air-conditioning system of a motor vehicle, there is provision for a collector (15) to be formed from a plurality of series-connected tubes (18) which extend between header tubes (10, 11) and the cross section of which is a multiple of the cross section of the flat tubes (13).
摘要:
A desorbable sorption filter, in particular for a heating or air-conditioning system of a motor vehicle, has a metallic support (12) which can be heated by flow of current and an adsorber (14) mounted at or on the support (12). To provide an improved, directly heatable sorption filter which particularly enables inexpensive production and good electrical and thermal conductive contact without the use of adhesives, it is proposed for the adsorber (14) to be of planar design and to be mechanically connected to the support (12, 112) by means of holding elements (26) formed integrally on the support (12, 112).
