Definitions

  • the present invention relates to a water cooling machine, intended to constitute a complement to the air conditioning machines in the refrigerated water condensing equipment, supplying precisely the condensation water.
  • the object of the invention is to eliminate, in this type of installation, the recovery towers, which are replaced by the machine of the invention, eliminating in parallel the problems inherent to said recovery towers, specifically noise pollution, water consumption and the proliferation of microorganisms harmful to human health.
  • recovery towers are used, usually located in the attics of buildings and consisting of water tanks that by means of fans, manage to lower the temperature to a value of the order of 3 to 5 degrees, using this chilled water, through the corresponding filter, to feed the air conditioners, or refrigerators existing in the different units of such buildings.
  • the water chiller machine that the invention proposes solves in a fully satisfactory way the problem described above, in each and every one of the different aspects mentioned.
  • the machine presents as one of its essential characteristics the one that uses a gas cooling circuit for water cooling, in which as a noise-generating operating elements exclusively a compressor and an axial fan participate, determinants of an acoustic contamination extraordinarily lower than that of the classic recovery towers.
  • said cooling circuit through a tubular evaporator, cools water in a closed circuit, which on the one hand eliminates the classic consumption and on the other hand isolates it from all types of germs in Pathological special.
  • a plurality of tubes participate through which the gas corresponding to the refrigeration circuit circulates, bathed by the water that arrives hot to said evaporator and that leaves cold, with the help of a circulating pump that sends the water towards a tank of inertia, where the mixing of the water from the condensation of the air conditioner in question is carried out, with which it comes from the chiller, controlling the mixture with a valve that allows to reach a setpoint temperature, to that water can be used again in condensation.
  • the cooling machine will be equipped with other typical accessories for its correct operation, such as boiler, filters, expansion valves, thermostats, pressure gauges, thermometers, etc., as will be seen later.

  • Figure 2. Shows a cross-sectional detail of the tubular evaporator that participates in said machine.
  • the water chiller that the invention proposes is constituted from a compressor (1), framed by a low pressure pressure switch (2) and a high pressure pressure switch (3), compressor connected to a condenser (4), assisted by an axial fan (5) and through a boiler (6), a filter drier (7), a liquid sight glass (8) , a solenoid valve (9) and an expansion valve (10), constitute a high pressure or liquid line, supply the gas in liquid phase to the tubular evaporator (11), specifically through a plurality of tubes (12) bathed by the water to be cooled, as seen in figure 2, producing in said evaporator (11) a phase change in the refrigerant fluid, which goes back to the gaseous state, to return to the compressor (1) and from there to the condenser (4), where it becomes liquid again.
  • the evaporator (11) has a hot water inlet (13), located at the bottom of it, and a cold water outlet (16), in which, through an anti-ice thermostat (17) and a discharge thermostat (18), a circulating pump (19) is established that supplies the cold water to an inertia tank (20), optionally replaceable by a exchanger, inertia tank where the mixing of the water from the evaporator (11) of the machine with the water from the condensation of the air conditioner occurs, which accesses the inertia tank (20) through the conduit (21 ) provided with an automatic loading valve (22) and a check valve (23), achieving in the inertia tank a temperature between 7 and 12 ° C and from where the cold water returns again to both the tubular evaporator (11) through the conduit (24), as with the air conditioner through the conduit (25), thermometers (26) and manometers (27) being provided at all points where it is necessary or convenient to control the temperature and pressure, and especially a set-up thermostat (28) in the outlet line

Abstract

L'invention concerne une machine de refroidissement de l'eau spécialement conçue pour former un complément des machines d'air conditionné dans les équipements frigorifiques condensés par eau en remplacement des tours de récupération. Elle est formée d'un circuit de refroidissement au gaz destiné à refroidir l'eau, qui utilise un compresseur (1), un condensateur (4) assisté par un ventilateur axial (5), un accumulateur hydraulique (6) et un évaporateur tubulaire (11), assistés par les compléments traditionnels, tels que pressostats, filtres, protections, valves solénoïdes et valves d'expansion. L'évaporateur tubulaire (11) tient lieu d'échangeur thermique entre le gaz correspondant au circuit de refroidissement et l'eau à refroidir, l'évaporateur (11) étant en rapport avec un dépôt d'inertie (20) dans lequel a lieu le mélange de l'eau réfrigérée provenant de l'évaporateur avec l'eau provenant de la condensation de l'appareil d'air conditionné couplé à la machine de sorte que le dépôt d'inertie conserve l'eau à une température comprise entre 7 et 12 °C et que le refroidissement de l'eau se fasse en circuit fermé. On obtient ainsi un dispositif éliminant les problèmes liés aux tours de récupération, tels que la pollution acoustique, la consommation de l'eau et la prolifération de micro-organismes nocifs pour la santé humaine.
