摘要： The invention provides an absorbing type water cooling-heating apparatus which employs an electrically-operated valve and an improved method of diluting a solution for automatically changing between heating operation and cooling operation only by operating a cooling-heating change-over switch. The apparatus comprises an evaporator for evaporating a cooling medium to cool cooling water, an absorber for causing a solution to absorb steam of the cooling medium evaporated in the evaporator to dilute the solution, a high-temperature regenerator and a low-temperature regenerator for concentrating the dilute solution, fed thereto from the absorber, by forming steam of the cooling medium, a condenser for condensing the steam of the cooling medium, produced in the low-temperature regenerator, into a liquid, a solution circulating pump for circulating the solution, a cooling medium spray pump for spraying the cooling medium, a cooling medium steam pipe connecting the interior of the high-temperature regenerator, in which the cooling medium steam is contained, to the interior of the evaporator in which the cooling medium is sprayed, a throttle device provided in the cooling medium steam pipe, an electrically-operated valve provided in the cooling medium steam pipe, and a cooling-heating change-over switch connected to the electrically-operated valve for switching the electrically-operated valve when changing the operation of the apparatus between a cooling mode and a heating mode.

摘要： A method of manufacturing a fan guard from a plate member wherein inward slits, each having at least a radial slit section are formed in a first section of the plate member located between a central section and a ring-like section radially outwardly spaced therefrom of the plate member such that the radial slit sections extend from the central section to the ring-like section in circumferentially spaced relation to each other. Radially outward slits, each having at least an arcuate slit section, are formed in a second section of the plate member located between the ring-like section and an outer peripheral section of the plate member such that the arcuate slit sections extend from the ring-like section to the outer peripheral section in circumferentially spaced relation to other. Portions each extending between the adjacent two radial slit sections are bent to form louvers. The central, first and ring-like sections are offset from the outer peripheral section while rotating the central, first and ring-like sections relative to the outer peripheral section, to twist portions extending between the adjacent two arcuate slit sections to form louvers.
