Embodiment Construction

[0012] In the method according to the invention, the cooling compressor 1 (water cooler) generates cooling water for the main circulation circuit 2 at a temperature of 12 degrees Celsius. The supply air cooling radiator 3 receives cooling water from the main circulation circuit 2 via the valve 5 and cools the supply air to the desired temperature.

[0013] The indoor unit, eg the cooled girder 4, receives the cooling water from the main circulation loop 2 via the valve 6 and mixes it typically to a temperature of 15 degrees Celsius. In normal operating conditions, water at 12 degrees Celsius does not remove moisture from the supply air (drying does not occur). It takes a lot of energy to extract water from the air (drying). The 12°C water cooler consumes less electricity because no drying occurs. It is therefore advantageous from an energy saving standpoint to orient the system so as to use hotter water, say 12 degrees Celsius, without drying out. In this case, the electric...

Abstract

Method for cooling supply air in the cooling system of a building, in which method the cooling water in the main circulation circuit (2) is cooled with a cooling compressor (1), and in which method cooling water is taken to the cooling radiator (3) from the main circulation circuit (2) for cooling the supply air, and in which method cooling water is taken to the room unit, such as to the chilled beam network (4) from the main circulation circuit (2) and mixed to the desired temperature, e.g. approx. 15 DEG C. The invention is implemented such that in an operating situation the cooling water of the main circulation circuit (2) is cooled to a temperature of over 7 DEG C, preferably to a temperature of approx. 12 DEG C, and such that in an exceptional situation such as when the supply air is humid, the temperature of the room unit, such as of the chilled beam network (4), is raised higher to prevent condensation and at the same time the temperature of the water of the main circulation circuit (2) is reduced lower.

Description

technical field [0001] The invention relates to a method for cooling supply air in a cooling system of a building, in which method the cooling water in the main circulation circuit is cooled by a cooling compressor, in which method the cooling water is sent from the main circulation circuit to the cooling A radiator for cooling the supply air and in this way cooling water from the main circulation loop to the indoor unit, for example to the beam grid to be cooled, and mixed to the desired temperature, for example about 15 degrees Celsius. Background technique [0002] The cooling of the air conditioner is usually achieved by using a separate water cooler, the task of which is to generate low temperature water for cooling in the air conditioner. Water at a temperature of 7°C for cooling the building's supply air (which may be outside air, recirculated air or a mixture thereof), usually used in cooling radiators or in corresponding equipment for cooling ventilation supply air....
